What is PPV?
Positive Pressure Units
Product Range
Also know as Positive Input Ventilation (PIV),
positive pressure fans draw fresh air from the
atmosphere, filters it and pushes into the dwelling
via a diffuser. All stale air in the property is forced
out through the natural forms of ventilation, such
as window mounted trickle vents.
Vent-Axia have two versions of a positive pressure
unit, one for loft mounting and a compact version
for properties without loft space that can be
discreetly mounted in a number of locations.
This entire design is a result of close consultation
with the public sector authorities. This valuable
feedback has resulted in special attention to
key design features such as robust construction,
longer life filters, user friendly operation, reliable
controls and wiring flexibility. Both versions can
be used for air replacement in conjunction with
an extract fan.

For controlling condensation particularly in the
refurbishment sector, the Vent-Axia PoziDry offers
a quick and simple solution. An out of sight loft
mounted positive input fan draws in fresh air from
the atmosphere, filters it and pushes it through a
ceiling mounted diffuser normally located over
the main stairwell of a two story dwelling or in
the main hall of a bungalow.

PoziDry Compact
The fresh, filtered airflow passes along the
ducting and terminates on an internal wall with
a discreet grille. This directs the airflow upwards
where the incoming air mixes with the warm air
that gathers at ceiling height.
The system automatically provides fresh,
tempered airflow into the home. There is minimal
power consumption and costs as little as one
penny a day to run. Creating an environment
where the damaging effects of condensation find
it hard to exist, benefits both the occupants and
the structure of the home.
The PoziDry Compact unit is easily installed discreetly above a cupboard in a kitchen

For those properties that do not have a loft,
Lo-Carbon PoziDry Compact provides an easy
to install solution. The wall mounted unit that can
be fitted in a number of locations around a single
floor flat or apartment.
Air is drawn into the PoziDry Compact unit via an
external inlet and through a short length of duct.
The specially developed fan/motor assembly
(using the LoWatt DC motor technology) draws
the air through an integral, high capacity,
washable filter. The backward curved impeller
guarantees increased efficiency, lower sound
levels and better performance.

The robust construction of the Lo-Carbon PoziDry
features a specially developed Lo-Carbon DC fan/
motor arrangement quietly delivers incredibly low
running costs. The Lo-Carbon PoziDry uses a sensor
to monitor the temperature in the loft, automatically
adjusting the air volume when necessary. ‘Trickle’
speed is automatically selected when the ambient loft
temperature is up to 18°C. ‘Normal’ is automatically
selected when the ambient loft temperature is
between 18 and 27°C.
The unit includes a filter with up to 5 years
maintenance free to reduce the number of call outs
needed throughout its life span.

Installation
It is simply installed, out of sight in the loft space it can
be suspended from a roof bean or be floor mounted,
with a purpose-designed diffuser normally located
over the stairwell of a conventional two story dwelling
or in the main hall of a bungalow. The Lo-Carbon
PoziDry is set to the appropriate speed at installation
based on the size of the dwelling, providing positive
pressure input ventilation. Background ventilation
openings provide the exhaust points.
If the ambient loft temperature exceeds 27’C, the
Lo-Carbon PoziDry will automatically switch to
standby (no airflow). The standby power consumption
is 2W.
In the case of the integral 500W heater version,
the heater element is automatically activated when
necessary and tempers the supply air to 10°C. Can
be used for air replacement in conjunction with an
extract fan.
The Lo-Carbon PoziDry uses a sensor to monitor the
temperature in the loft, automatically adjusting the air
volume when necessary.
‘Trickle’ speed is automatically selected when the
ambient loft temperature is up to 18°C.
The unit includes a time elapsed meter to enable
precise running information
Speed Control
With selection of 2 of 6 speeds available up to
50l/s, the unit is suitable for houses up to 400m3.
Heater
An optional comfort heater is available for operation
when the incoming air temperature becomes low.
Motor
The electronically controlled DC motor is manufactured
with long life ball bearings and is fitted with Standard
Thermal Overload Protection (S.T.O.P.). Suitable for
ambient operating temperatures of -25˚C to +40˚C.
For complete peace of mind the Vent-Axia Lo-Carbon
PoziDry is backed by a 5 year guarantee.
