Why compressed air drying?
Compressed air
Compressed air treatment
is energy in the form of compressed ambient
air. Compressed air is permanently trying to
expand back to atmospheric pressure and
thus performs work during the expansion
process. Besides electrical energy compressed air is one of the most important
forms of power for industrial production
processes and is widely used thanks to
numerous advantages:
removes the unwanted contamination and
provides the purity of the compressed air
required for the application, e.g. standard
instrument air, technically oil-free compressed air up to sterile ultra-pure air or
medical breathing air. Many industries have
a specific air quality requirement governed
by best practice or legislation.

Can be produced locally and on demand
Can be stored easily and without losses
Can be transported easily
High amount of energy per volume
Can be easily converted to other forms of
energy, e.g. blast air, fast linear movement
with increased force, rotary movement
with increased torque, in a space-saving
way
· Versatile applications
The compressed air contains contamination
and moisture from the ambient air which
are concentrated according to the operating
pressure. Oil-lubricated compressors will
add amounts of oil to the compressed air.
When the compressed and hot air is cooled
down to an appropriate operating temperature, larger amounts of water will condense
(condensate).
Untreated contamination in the compressed
air would contaminate and damage the
compressed air system, the compressed air
consumers and the products that come into
contact with the compressed air.
The aim of compressed air treatment is to
ensure continuous and trouble-free operation of applications using compressed air,
to minimise downtimes, unscheduled maintenance and repair work, and to remove
specific contamination that may be harmful
to the product.

COMPRESSED AIR TREATMENT
And, most of all, compressed air treatment
actively contributes to environmental protection as well as to occupational health and
safety. Liquid oil droplets, finest oil mist, oilcontaminated solid particles and gaseous,
foul-smelling oil vapour, i.e. contamination
which occurs on site during compressed air
production, can be completely eliminated
and thus will not contaminate the local
environment.
The compressed air treatment system comprises several consecutive treatment components, referred to as treatment chain,
which treat the compressed air in stages in
order to achieve the required purity.
Compressed air drying
is an elementary key component in the
treatment chain. The task of compressed air
drying is to reduce the amount of moisture
contained in the compressed air to a defined
residual value.
At the outlet of a compressor there is 1000
times more moisture in the compressed air
compared with the sum of all other contaminants. The compressed air is 100% saturated with water moisture which means that
even the slightest temperature reduction of
the compressed air on its way to the compressed air consumers causes water condensation and thus the formation of condensate
within the compressed air.
Compressed air dryers thoroughly eliminate
the moisture and thus produce dry, undersaturated compressed air in which no further condensation can occur – neither within the compressed air system nor at the
compressed air application.
Moisture in the ambient air is vital for us and fundamental for our life. In compressed
air, however, moisture is a “contaminant”, especially when it condenses into liquid
water in the compressed air or leads to a build-up of ice, and therefore it must be
separated.
Compressed air is ambient air that has been drawn in and compressed by a compressor. As a result, the compressed air also contains moisture from the ambient air
which varies according to seasonal and meteorological fluctuations. What is more,
the compression results in compressed air that is normally 100% saturated with
moisture when it exits the compressor (100% RH).
The maximum amount of moisture that the compressed air can hold depends on
the temperature and is shown by the vapour pressure curve or moisture table. The
higher the temperature, the more moisture the compressed air can hold. If, when
cooling, the amount of moisture in the compressed air is higher than the maximum
possible amount for the reduced temperature, the excess moisture will condense as
liquid water. Condensate arises in the compressed air.
The moisture-saturated compressed air at the outlet of the compressor is warmer
than the ambient air and cools on its way through the “cold” pipelines. Condensate
arises in the compressed air. In the case of outdoor installations (seasonal cold
temperatures) and the use of compressed air by the application itself (expansion
cooling), the compressed air cools again and further condensate arises, sometimes
even until ice is formed.

Typical contaminations in compressed air
Compressed air dryers remove the moisture and create dry, undersaturated compressed air.
Different dryer types create different degrees of dryness.
It is useful to state the degree of drying of the compressed air as the pressure dew-point in °C.
If the compressed air temperature is higher than the pressure dew-point,
then no condensate will form and the compressed air is and will remain dry.
The different dryer types and the compressed air dryer models available from FST
GmbH will be described in more detail in
this brochure. The foldout application and
the compressed air purity guide can be used
as additional assistance in determining an
optimised and individual system solution.

+7°CÙ+3°C
Pressure dew-points down to +3°C can be achieved with refrigeration dryers.
Fields of application:
The areas of application for compressed air dried with refrigeration dryers are generally frost-free
indoor installations and compressed air applications with low requirements in terms of the degree
of dryness, such as instrument air, blast air, pneumatic tools. Refrigeration dryers are usually used
to centrally prepare the compressed air to a “basic degree of dryness”, which is suitable for most
installed compressed air applications. Higher degrees of dryness are created for individual applications in a decentralised process and thus only produced in the required amounts.

Refrigeration dryers promote premature condensation of the moisture contained in the compressed air by actively cooling it. The condensate that forms is collected in the refrigeration dryer
and drained off. The compressed air is then brought to a undersaturated state through warming
and thus dried.
Refrigeration dryers are suitable for continuous operation and are available for all volume flow
ranges. The pressure range usually extends to 16 bar, however special versions are also available
for higher operating pressures.

Pressure dew-points down to -70°C can be achieved with adsorption dryers.
Fields of application:
The areas of application for compressed air dried with adsorption dryers are generally outdoor
installations that are at risk of frost and compressed air applications with very high requirements
in terms of the degree of dryness, such as process air in the food, electronic, pharmaceutical,
chemical, measuring and process technology industries. Adsorption dryers are used both in
centralised and decentralised compressed air treatment due to their unrestricted scalability.

Adsorption dryers remove the moisture directly from the compressed air. The desiccant used in
adsorption dryers binds the water molecules and completely separates the moisture from the
compressed air. In order to enable continuous operation, adsorption dryers consist of two vessels
filled with desiccant, which are alternately used to dry the compressed air (adsorption) and regenerate the desiccant.
Adsorption dryers are suitable for continuous operation and are available for all volume flow and
pressure ranges. Adsorption dryers also offer different regeneration types for efficient compressed
air drying in the various performance ranges.

Pressure dew-points down to -40°C can be achieved with membrane dryers.
Fields of application:
The areas of application for compressed air dried with membrane dryers are compressed air applications with increased requirements in terms of the degrees of dryness and low compressed air
demands (< 50 m³/h), such as measuring technology and test stations. Membrane dryers are only
used to dry low volume flows due to their mode of operation and ratings.

Membrane dryers consist of a variety of hollow fibre membranes which only allow water molecules to diffuse through them. Expanded, compressed air from the membrane dryer outlet is led
to the outside of the hollow fibres and removes the moisture from the compressed air flowing
through the hollow fibres. The membrane dryer technology enables small, compact designs and
does not require any electricity.

Refrigeration dryers consist of two heat exchangers and a controlled refrigerant circuit.

During the entire cooling process, moisture in the compressed
air precipitates in the form of condensate which is centrally

air in counterflow direction and thus brought to an undersaturated state. Provided that the compressed air temperature
does not fall below the pressure dew-point, no more condensate can arise.
Control types
To prevent the refrigeration dryer from freezing when being operated at partial load, the cooling capacity generated by the refrigerant circuit
needs to be controlled.
Hot gas bypass control
DFX series
2-point control
DFE series
Cascade/speed control
DFL series
In the case of hot gas bypass control, the
cooling capacity is controlled by means
of a simple, mechanical proportional
controller. Depending on the load of
the refrigeration dryer, the proportional
controller redirects part of the cooling
capacity and thus controls the cooling
energy supplied to the refrigerant-to-air
heat exchanger.
In the case of 2-point control, the refrigerant circuit is combined with a thermal
mass storage system. Depending on the
load of the refrigeration dryer, the refrigerant circuit is switched on and off to
control the cooling capacity. The thermal
mass storage smoothes the temperature
gradation and ensures suitable switching
intervals.
In the case of cascade control, the cooling
capacity generated by the refrigerant
circuit is controlled by switching the refrigerant compressors on and off.
The hot gas bypass control enables compact refrigeration dryer designs and is
useful for refrigeration dryers in the lower
to mid performance range due to its
simple construction.
Significant energy savings can be gained
with 2-point control, depending on the
load of the refrigeration dryer. The 2-point
control is useful for refrigeration dryers in
the mid and high performance ranges.
In the case of speed control, the refrigerant compressor in the refrigerant circuit is
controlled with variable speed, the cooling
capacity is thus controlled directly in proportion to the load of the refrigeration dryer.
Significant energy savings can be gained,
depending on the load of the refrigeration
dryer. The cascade/speed control is useful
for refrigeration dryers in the high performance range.

“Energy guzzlers”
“Energy savers”
High differential pressure
Elaborate piping, insufficiently dimensioned pipeline cross-sections
or heat exchangers create high pressure loss. The air compressor
has to compensate for the pressure loss with high, additional
energy input.
Low differential pressure
Fully-integrated, generously sized heat exchangers and connection
cross-sections ensure low pressure loss. The lower the pressure
loss, the lower the operating pressure of the air compressor and
thus the lower its power consumption.
High thermal losses
Due to insufficient or incomplete insulation, cold is lost to the environment. This cold is no longer available for the drying process and
must be generated by the refrigerant compressor using additional
energy input.
Low thermal losses
High-quality and complete insulation minimises thermal losses.
The cold capacity generated by the refrigerant circuit is completely transferred to the drying process and used with maximum
efficiency.
Time-controlled condensate drains
Time-controlled condensate drains discharge the condensate at
fixed, pre-set intervals. The amount of condensate arising in compressed air systems varies greatly, depending on the operating conditions. With time-controlled condensate drainage, condensate
backflow arises if the intervals are too long or a high amount of
compressed air is lost if the intervals are too short. This is compressed air which has been generated by the air compressor using
a large amount of energy.
Level-controlled condensate drains
Level-controlled condensate drains measure the accumulated condensate via an integrated level measurement system and discharge
the condensate in an automatic, loss-free, electronically controlled
and monitored way.

Control types
In fixed cycle adsorption dryers work with fixed cycle times under the assumption of permanent full load, regardless of the inlet conditions.
The adsorption and regeneration phases are equally as long.

Variable cycle with dew-point dependent control
Images show an example of a heatless adsorption dryer
Adsorption dryers consist of two pressure vessels, which are both filled with desiccant and are alternately operated via switch-over. The
compressed air to be dried flows through a vessel where the moisture is thoroughly removed by the desiccant (adsorption). At the same time,
the moisture stored in the desiccant in the second vessel is removed (regeneration). If the desiccant in the vessel in which adsorption takes place
is saturated with moisture then the vessels are switched and the process begins again. One complete run of adsorption and regeneration in a
vessel is called a cycle, and the time required is the cycle time.
In variable cycle with dew-point dependent control, a dew-point sensor detects the pressure dew-point at the outlet of the adsorption dryer and
extends the adsorption time according to the actual inlet conditions. The extended adsorption time results in energy saving phases, in which no
regeneration energy is required. In this way, energy savings of up to 90% can be achieved.

Heatless regeneration
DPS, DHM, DHW series
Heat regeneration
DTS series
Regeneration with compressor heat
DTC series
In the case of heatless regeneration, some
of the dried compressed air from the
dryer outlet is taken, decompressed to
atmospheric pressure and fed through
the regeneration vessel in order to regenerate the desiccant.
During heat regeneration, ambient air
is drawn in by a vacuum pump/blower,
heated to approximately 160°C and fed
through the regenerating vessel in order
to regenerate the desiccant.
In the case of heat regeneration utilising
the compressor heat, hot compressed air
from an oil-free compressor is used for
regeneration of the desiccant.
The dried, decompressed and thus extremely undersaturated air extracts the
moisture stored in the desiccant and
discharges it to the environment via a
silencer.
The hot air removes the moisture from
the desiccant and releases it to the
environment at the outlet. If there is no
suitable ambient air available, expanded
compressed air can be used as an alternative.
For DPS series dryers, the change interval
between adsorption and regeneration is
5 minutes at nominal conditions. The
cycle time is therefore 10 minutes.
For DTS series dryers, the change interval
between adsorption and regeneration is
6 hours at nominal conditions. The cycle
time is therefore 12 hours.
The hot, compressed air removes the
moisture stored in the desiccant and is
then led to a condensation cooler. There
the moisture condenses and is drained off
as condensate.
For DTC series dryers, the change interval
between adsorption and regeneration is
3 hours at nominal conditions. The cycle
time is therefore 6 hours.

The compressor synchronisation control is normally used with heatless adsorption dryers and can be used both in fixed as well as variable cycles.
The compressor synchronisation control synchronises the adsorption dryer with the air compressor. If the compressor stops then no compressed
air is generated for drying and the adsorption dryer stops its cycle (standby). Likewise, if the compressor starts, the adsorption dryer continues
its cycle. No regeneration energy is required in the standby phases. This means that considerable energy savings can be achieved.

dew-point dependent control
Take note!
Adsorption dryers are always designed for full load operation, i.e. maximum volume flow,
minimal operating pressure and maximum inlet temperature, in order to ensure the required
pressure dew-point is achieved even at correspondingly high load.
In full load operation, the adsorption and regeneration phases are equally as long. There is a
permanent requirement for regeneration energy.
However, the specified full load operating conditions rarely occur simultaneously, due to:

An adsorption dryer fitted with a dew-point sensor can detect this type of partial load situation
and implement corresponding energy saving phases.
The potential energy savings can be approximately determined with the following diagram
using the example of a heatless adsorption dryer.
The actual energy requirement and thus the actual energy saving results from the product of the
individual saving values per parameter, in our example
“Energy guzzlers”
“Energy savers”
„Cheap“ desiccant
Large amounts of regeneration air for heatless adsorption dryers
and high regeneration temperatures for heat regenerated adsorption dryers require a large amount of energy for regeneration.
High-quality desiccant
High quality desiccants result in stable, low pressure dew-points
with minimum energy input for regeneration and at the same time
they normally provide distinctly better long-term stability and a
longer service life.
Short cycle times
The shorter the cycle time, the more often pressurisation of
the regenerating vessel is required and the higher the compressed
air consumption. Short cycle times are normally determined
by the desiccants themselves or through reduced amounts of
desiccant.
Long cycle times
Long cycle times keep the number of pressurisation phases, and
thus the compressed air consumption, to a minimum, through
the use of high-quality desiccant in appropriate quantities.
Operation without dew-point dependent control
Without dew-point dependent control there is a permanent
requirement for regeneration energy regardless of the load of
the adsorption dryer. As adsorption dryers normally work with
varying volume flows, operating pressures and inlet temperatures
in partial load mode, the energy saving potential is not utilised.
Operation with dew-point dependent control
Dew-point dependent control facilitates energy saving phases
without the need for regeneration energy of up to 230 minutes

are typically achieved with dew-point dependent control.
Regeneration process with purge air requirement
Some regeneration processes for heat regenerated adsorption dryers require purge air. Purge air is large amounts of dry compressed
air, which is required over long periods to support the cooling
phase. The air compressor uses a large amount of additional energy
input to generate the purge air.
Regeneration process without purge air requirement
Regeneration processes that do not require purge air are available,
e.g. fast cooling with vacuum or fast closed loop cooling. Compressed air is not required throughout the entire regeneration
phase.
Only „standard solutions“ available
If heat regenerated adsorption dryers do not have the option to
use the customer‘s alternative energy sources, e.g. hot steam, hot
water, cooling water, etc. then the thermal energy required for the
regeneration must be generated using electricity.
Integration of external heat or cold sources
Integration of the customer‘s existing alternative energy sources,
such as hot steam, hot water, cooling water, etc. can result in
enormous energy savings. These cost-effective alternative sources
reduce the energy costs of the adsorption dryer.
Actual energy requirement = 90% x 70% x 50% = 32% , i.e. 68% energy saving
The question of which regeneration type and which control type is the best for a specific application should be answered by means of a professional
profitability calculation. The energy savings and the resulting overall costs or payback periods that can be achieved through individual selection
and design of the dryer are enormous and sometimes amount to values of up to 90%.

All FST adsorption dryers have a free
flow area at the entrance to the desiccant filling, created by a stainless steel
demister/screen placed in the vessel.
Combined with the adsorption flow
direction from bottom to top, the free
flow area ensures optimal air distribution over the entire cross-sectional area
as well as pre-separating liquid contaminants out of the compressed air. The
result is a uniform flow through the
desiccant over the entire filling volume
without any dead spaces or “moisture
clusters” in the desiccant bed.
Heatless adsorption dryers from FST are
filled with robust, durable and high-grade
drying molecular sieve desiccant. With its
large specific surface and high drying capacity, molecular sieve ensures a stable and low
pressure dew-point down to -70°C. This results in long, energy-saving cycle times. Molecular sieve also has the special ability to
achieve stable and low pressure dew-points
even under conditions that are unfavourable
for desiccant, e.g. in the case of low moisture input due to an upstream refrigeration
dryer.
Heat regenerated adsorption dryers are
filled with high-capacity, high-grade drying
silica gel N desiccant. Silica gel N possesses a
comparably large specific surface and drying
capacity as molecular sieve, it also achieves
pressure dew-points down to -70°C, however it possesses a distinctly lower regene-
ration temperature which enables energy
savings of up to 33% to be achieved.
All FST adsorption dryers are filled with a
2-layer desiccant bed, i.e. with an additional
water resistant silica gel WS safeguard layer
at the inlet of the desiccant filling. This reliably prevents degradation of the desiccant
caused by liquid water and ensures continuous, stable operation of the adsorption dryer
as well as long service life of the desiccant.

Regeneration from top to bottom prevents turbulence of the upper, loose
desiccant during depressurisation. This
considerably reduces desiccant abrasion and development of dust during
regeneration.
During regeneration, moisture stored in
the desiccant, is removed from top to
bottom in reverse flow to adsorption
via the bottom, wet and water resistant area at the inlet of the dryer (reverse flow principle). This creates a
highly regenerated layer of desiccant at
the outlet of the dryer, which ensures a
stable and low pressure dew-point for
the next switch-over.
The reduced desiccant abrasion and the
discharge of moisture via the water resistance area also extends the service
life of the desiccant and thus the performance stability of the entire adsorption dryer.

Individual valve control
Each valve is controlled individually
with a time-delay, which results in overlap-free switch-over without pressure
peaks between adsorption and regeneration. The flow paths through the
adsorption dryers are always clearly defined. This eliminates possible incorrect
flow from passive devices (e.g. shuttle
valves) and thereby prevents malfunction of the dryer. There is always an un-

dryer even in the event of a malfunction.
Pneumatically driven 4/2-way valves,
which are mechanically connected
with a cardan shaft, guarantee an overlap-free, synchronised switch-over between the vessels. In addition, there is
always an unrestricted flow path for the

of supply voltage. This ensures compressed air supply downstream of the

External heater
In comparison to two internal heaters
integrated in the vessels, an external
heater offers many advantages. The
external heater is located outside the
pressure vessel and can thus be directly
and easily accessed for maintenance
without any height restriction for disassembly. There is no loss of pressure
in the adsorption flow path due to an
inactive heater. The external heater,
located outside the vessel, also permits
compact designs as well as allowing the
pressure vessel to be completely filled
with desiccant. In addition, the external
positioning facilitates integration of
the customer‘s existing heat sources,
such as hot steam or hot water, into the
dryer system and thereby easily and
cost-effectively converts them into
energy savings.

The DTS..BVL series combines the advantages of blower and suction mode and
thus achieves the best possible total
energy balance. Heating is carried out in
blower mode using the blower heat and
thus reduces the energy requirement of
the downstream electric heating by up to
21%. Cooling is carried out through fast
cooling in suction mode without purge air
(see information) and also in closed loop
via a heat exchanger. The cooling phase is
thus independent from ambient air and
climatic conditions. The customer‘s existing cold sources, such as cooling water,
cold water, can be integrated for further
energy optimisation. Through serial heat-

Series DPS 120-630 adsorption dryers can
dry the compressed air to a pressure dewpoint of -25°C, -40°C or down to -70°C. In
doing so, they create dry, thoroughly undersaturated compressed air in which no further condensation takes place and thus no
formation of liquid water can occur at compressed air temperatures above the pressure dew-point. Additionally a separate
downstream activated carbon oil vapour
adsorber can be provided (see DSS series).
Series DPS 120-630 adsorption dryers consist of welded and coated steel vessels,
which are pressure rated up to 11 bar and
generously sized, zinc-coated piping and
classic individual valves for low differential
pressures in this performance range. They
feature a pneumatically controlled 3/2-way
ball valve with full cross section flow as well
as pneumatically controlled angle valves
from well-known manufacturers. The valves
are individually controlled with a time delay
which means there is no overlap. The dryers
are operated with a 2-layer desiccant bed,
consisting of 20% water resistant silica gel

carbon. Flow distributors or stainless steel
demister at the inlet and stainless steel
screens or stainless steel demister at the
outlet ensure uniform flow and reduced
abrasion of the activated carbon.
Series DSS activated carbon oil vapour adsorbers reduce the oil vapour content of the
compressed air to low residual levels. Oil
vapour is the second largest vapour phase in
compressed air and, like moisture, is highly
likely to condense – in the case of oil vapour
it condenses to form liquid oil. High-grade
removal of oil vapour using an activated
carbon oil vapour adsorber reliably prevents
condensation processes during the cooling
of compressed air and thus the formation
of liquid oil. In addition, activated carbon oil
vapour adsorbers remove a variety of other
hydrocarbons, odours and flavours.

adsorbers consist of a powder-coated aluminium profile body, which is pressure-rated
up to 16 bar and on which two end plates are
mounted. Series DSS 10-100 and DSS 120630 activated carbon oil vapour adsorbers
Series DSS activated carbon oil vapour
adsorbers are fitted with an oil indicator
as standard, the DSS 10-630 models also
feature a vessel pressure gauge. The oil indicator‘s control point is approximately 15%
before the activated carbon filling needs to
be replaced in order to ensure sufficient
lifetime reserve until the activated carbon is
replaced.

Series DTS..V adsorption dryers can dry the
compressed air to a pressure dew-point of
-25°C, -40°C or down to -70°C. In doing so,
they create dry, thoroughly undersaturated
compressed air in which no further condensation takes place and thus no formation of
liquid water can occur at compressed air
temperatures above the pressure dew-point.
Additionally a separate downstream activated carbon oil vapour adsorber can be
provided (see DSS series).
Series DTS..V adsorption dryers consist of
welded and coated steel vessels, which are
pressure-rated up to 11 bar, and generously
sized, zinc-coated piping. The flow paths are
switched over via pneumatically controlled
4/2-way plug valves, which are mechanically
connected to each other via a cardan shaft
regenerating adsorption dryers and enables
both independent operation of the dryer as
well as integration into the control system

of 30% water resistant silica gel WS and 70%
high-grade drying silica gel N. The regeneration takes place with ambient air, which is
drawn in by a vacuum pump, warmed in
an electric heater and fed through the desiccant (heating). Cooling is carried out in a
similar manner with the electric heater
switched off – without the need for purge
air.
Further energy savings can be made through
integration of the customer‘s alternative

Series DM membrane dryers can dry
small amounts of compressed air to
pressure dew-points down to -40°C. In
doing so, they create dry, thoroughly
undersaturated compressed air in
which no further condensation takes
place and thus no formation of liquid
water can occur at compressed air
temperatures above the pressure dewpoint.
The pressure dew-point achieved by
the membrane dryer is dependent on
the inlet temperature and the set
amount of purge air. From an energy
point of view, the maximum pressure
dew-point reduction should be 30°C.
For example, at an inlet temperature of
20°C, a pressure dew-point of -10°C is
achieved.
Series DM membrane dryers consist of
hollow fibre membrane bundles, which

Series FCA point of use dryers can dry
small amounts of temporarily required
compressed air to pressure dew-points
down to -40°C. In doing so, they create
dry, thoroughly undersaturated compressed air in which no further condensation takes place and thus no formation of liquid water can occur at
compressed air temperatures above
the pressure dew-point.
water molecules and therefore moisture can diffuse through the fine pores
of these bundles. Expanded, dry
compressed air (purge air) from the
membrane dryer outlet is led to the
outside of the hollow fibres and
removes the moisture from the compressed air flowing through the hollow
fibres by the means of diffusion.
Solid and oily contaminants must be
kept away from the sensitive hollow
fibre membranes. If the compressed air
purity at the membrane dryer inlet is
not sufficient, then a suitable pre-filter
must be used.
Series FCA point of use dryers are also
used when sensitive applications with
high requirements in terms of the degree of dryness of the compressed air
need to be protected against unexpected moisture appearance (safety level
for adsorption dried compressed air).
Series DM membrane dryers are compact, fully integrated compressed air
dryers. The DM-SWC series also have
a 3 stage purge air setting option for
achieving different pressure dewpoints.
removed from it by the desiccant (adsorption). The integrated dust filter
collects any abrasion particles from the
desiccant. Downstream dust filtration
is not required.
Oily contaminants would stick to the
desiccant and therefore need to be
kept away from it. If the compressed air
purity at the point of use dryer inlet is
not sufficient, then a suitable pre-filter
must be used.
The optional moisture indicator approximately determines the degree of
dryness of the compressed air and thus
when the desiccant cartridge needs to
be replaced.
Series FCA point of use dryers consist
of housings which are pressure-rated
up to 16 bar and a desiccant cartridge
with integrated dust filter. As the compressed air flows through the desiccant
cartridge, the moisture is thoroughly
