Compressed air drying

Compressed air drying If compressed air simply is to be dry Good to know What is …? 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.

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. Dust 0.001 g 1 mg Hydrocarbons 0.01 g 10 mg Moisture 40 g 40,000 mg 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.

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. ͻ ŽŵƉƌĞƐƐĞĚĂŝƌĚƌǇŝŶŐŝŶĐĞŶƚƌĂůĐŽŵƉƌĞƐƐĞĚĂŝƌƚƌĞĂƚŵĞŶƚ to a “basic degree of drying”, suitable for all volume flow ranges Refrigeration dryers promote premature condensation of the moisture contained in the compressed air by actively cooling it.

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.

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.

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.

The adsorption and regeneration phases are equally as long. Adsorption Regeneration Adsorption Regeneration Fixed cycle Vessel 1 Adsorption Regeneration Vessel 2 Regeneration Adsorption 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. Vessel 1 Adsorption Regeneration Vessel 2 Regeneration Energy saving phase Energy saving phase Adsorption ZĞŐĞŶĞƌĂƟŽŶƉƌŝŶĐŝƉůĞƐ 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. ŽŵƉƌĞƐƐŽƌƐǇŶĐŚƌŽŶŝƐĂƟŽŶ 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.

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: ͻ ^ĞĂƐŽŶĂůĂŶĚŵĞƚĞŽƌŽůŽŐŝĐĂůĨůƵĐƚƵĂƚŝŽŶƐŽĨƚŚĞŝŶůĞƚƚĞŵƉĞƌĂƚƵƌĞ ͻ &ůƵĐƚƵĂƚŝŽŶƐŽĨƚŚĞŽƉĞƌĂƚŝŶŐƉƌĞƐƐƵƌĞǁŝƚŚŝŶŝƚƐƉƌĞƐƐƵƌĞͲďĂŶĚ ͻ sĂƌǇŝŶŐǀŽůƵŵĞĨůŽǁƐĚƵĞƚŽƌĞƋƵŝƌĞŵĞŶƚĨůƵĐƚƵĂƚŝŽŶƐ 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 ĨŽƌŚĞĂƚůĞƐƐĂĚƐŽƌƉƚŝŽŶĚƌǇĞƌƐ;ϵϲйͿĂŶĚƵƉƚŽϴϰŚŽƵƌƐĨŽƌŚĞĂƚ ƌĞŐĞŶĞƌĂƚĞĚĂĚƐŽƌƉƚŝŽŶĚƌǇĞƌƐ;ϴϴйͿƉĞƌĐǇĐůĞ͘^ĂǀŝŶŐƐŽĨϮϬͲϳϬй 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%. 14 ŶĞƌŐǇĞĨĨŝĐŝĞŶƚĂĚƐŽƌƉƚŝŽŶĚƌǇĞƌƐĂůƐŽŽĨĨĞƌƚŚĞůŽǁĞƐƚƚŽƚĂůĐŽƐƚƐ͕ǁŚŝĐŚĐŽŵƉƌŝƐĞĞŶĞƌŐǇ;шϴϬйͿ͕ŵĂŝŶƚĞŶĂŶĐĞĂŶĚŝŶŝƚŝĂůŝŶǀĞƐƚŵĞŶƚĐŽƐƚƐ͘ In addition, the criteria of operational reliability, durability, long-term stability and easy maintenance, which influence the total cost, should be evaluated. 15 Overview The advantages at a glance ĚƐŽƌƉƟŽŶĚƌǇĞƌĂůůƐĞƌŝĞƐ WƌĞƐƐƵƌĞǀĞƐƐĞůƐD/E'ZDEzǁŝƚŚŚŝŐŚͲƋƵĂůŝƚǇĐŽĂƟŶŐ The pressure vessels of FST adsorption dryers are manufactured in Germany and have been produced under a certified quality management system. The pressure vessels are designed, manufactured and inspected according to recognised regulations and standards (AD2000 Codes, Directive 97/23/ EC) and comply with the highest and latest safety standards. The high-quality, durable coating of the pressure vessel also ensures a long service life and the safe operation of the adsorption dryer.

Fully galvanised piping rounds off FST‘s claim of high-quality and long life adsorption dryers. International approvals such as ASME (USA), GOST (Russia), SQL (China stamp), AS1210 (Australia), etc. or application-specific approvals such as DNV (Det Norske Veritas), Germanischer Lloyd, etc. are available. 9 Maximum operational reliability 9 Rugged design and long life ^ƚĂŝŶůĞƐƐƐƚĞĞůƐĐƌĞĞŶĂŶĚĂĚƐŽƌƉƟŽŶĨƌŽŵďŽƩŽŵƚŽƚŽƉ 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 regeneration 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. 9 Maximum operational reliability total operating costs 9 –Minimum High-quality, consistent performance and long life desiccant bed – Efficient and effective drying – Energy efficient regeneration principles – Low maintenance costs Desiccant type Specific surface Required temperature for heat regeneration Energy requirement for desorption of water Molecular sieve ϴϬϬŵϸͬŐ ϮϭϬΣ ϭ͘ϮŬtŚͬŬŐ Silica gel N ϳϱϬŵϸͬŐ ϭϲϬΣ Ϭ͘ϴŬtŚͬŬŐ Silica gel WS ϲϱϬŵϸͬŐ ϭϲϬΣ Ϭ͘ϴŬtŚͬŬŐ Activated alumina ϯϱϬŵϸͬŐ ϭϴϬΣ ϭ͘ϭŬtŚͬŬŐ 16 total operating costs 9 Minimum – High-quality, consistent performance and long life desiccant bed – Efficient and effective drying – Low differential pressure 9 Easy maintenance Pre-separation of liquid contaminants reduces the liquid condensate load of the desiccant and also reduces blockage of the desiccant through oily contaminants in the compressed air.

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. total operating costs 9 Minimum – High-quality, consistent performance and long life desiccant bed 17 Overview The advantages at a glance ,ĞĂƚƌĞŐĞŶĞƌĂƚĞĚĂĚƐŽƌƉƟŽŶĚƌǇĞƌ 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- Mechanically linked 4/2-way valves restricted flow path for the compressed air, even in the case of loss of supply voltage. This ensures compressed air supply downstream of the adsorption 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 compressed air, even in the case of loss of supply voltage. This ensures compressed air supply downstream of the adsorption dryer even in the event of a malfunction. 9 Maximum operational reliability 9 Maximum operational reliability total operating costs 9 Minimum – Low differential pressure 9 Rugged design and long life 9 Easy maintenance W^ϭͲϴǁŝƚŚůŽŽƐĞĚĞƐŝĐĐĂŶƚĮůůŝŶŐ Even the smallest DPS series have loose desiccant filling.

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.

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.

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 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.

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.
