Vant Axia Pozidry Pro with Heater - 476311


The perfect solution for hard to cure mould and condensation properties. Improving indoor air quality and preventing moisture build-up within the home. Backed up with a 5 year maintenance free guarantee.

PoziDry Pro™ improves indoor air quality and quickly eradicates conditions that lead to mould growth, reducing the risk of health issues in the home. The unit is unobtrusive, near silent running and has low operating costs

Loft mounted positive input fan draws fresh air from atmosphere, filters it and pushes into the dwelling via a ceiling mounted diffuser. All stale air in the property is forced out through the natural forms of ventilation, such as window mounted trickle vents and bathroom extractor fans

The 500W heater is fully flexible and has the option to be installed at diffuser level to reduce heat loss through the ducting. This means more heat enters the habitable areas of the house. Smart Sense controls allow the Pozidry Pro to be adjusted fully when the heater is activated making it adaptable for all lifestyles.


The Lo-Carbon PoziDry pro uses a sensor to monitor the temperature in the loft, automatically adjusting the air volume when necessary. The unit will continuously ventilate silently in the background whilst in ‘Trickle’ mode. Once the unit automatically senses excess heat being lost into the loft the airflow will increase to ‘Normal’ mode to recover heat that would otherwise be lost through the roof. During summer months should the loft exceed 27°C the unit will enter ‘stand-by’ mode in order stop the circulation of warm air allowing for a more comfortable living environment.

PoziDry Pro Heater models automatically turn on the 500W heater to boost air temperature by 10°C during colder months. Under assessment with BBA.


Up to 5 year maintenance free G4 filter as standard Standard (PM10 filtration) which filter out many every day pollutants such as pollen & dust.

Optional F7 filters are available (PM2.5 Filtration) removing tobacco smoke, diesel particulates, spores and a number of bacterias


The unit can be controlled by Smart Sense™ Technology – Easy set up and smart data logging capabilities all accessed via the intuitive 3 button menu on the unit

Speed control selection is easy. Once house size is selected based on number of bedrooms, PoziDry Pro automatically selects the correct Trickle and Normal speeds. Should you need to adjust speed manually this can be done easily.

Data Logger allows the unit to record how long it has been running in each of its speeds. It also measures the number of days the product has been switched on to provide precise running information. Smart Sense technology can also record the duration of heater activity and energy used


The Lo-Carbon PoziDry Pro features a specially developed Lo-Carbon DC fan/motor arrangement which runs quietly and delivers incredibly low running costs of less than £3 per year to run, The motor operating tempature is -25/40`c


The Lo-Carbon PoziDry Pro is uniquely flexible in its installation methods, high sided anti vibration legs and a hanging kit both come as standard, allowing the PoziDry Pro to be installed quickly in any sized loft.

The easy carry handle incorporated into the body makes carrying the unit easy and safe; especially useful when lifting the unit through loft hatches.

The unit is supplied with a purpose designed diffuser to be located over the stairwell of a conventional dwelling or in the main hall of a bungalow.

Using Smart Sense technology the unit is easily set to the appropriate speed at installation based on the size of the dwelling. Background ventilation openings provide the exhaust points.

En-suites and utility areas should be serviced by continuous mechanical extract ventilation
