Vent-Axia launches new Pozidry PIV units for social housing sector

Vent-Axia, the market leader in social housing ventilation, has introduced the Lo-Carbon™ PoziDry and PoziDry Compact – four cost-effective and quiet-running Positive Input Ventilation (PIV) units designed to meet the precise refurbishment requirements of public sector housing specifiers.

The PoziDry and PoziDry Compact provide an especially quick and simple to install solution to control condensation and reduce the time and cost of maintenance caused by excessive damp and mould growth.  PIV, or Positive Pressure Units (PPU), work by drawing in fresh air from outside, filtering it, then pushing it into the dwelling via a central diffuser, typically located over the stairwell or hallway. Stale air can be forced out of the property either through window trickle vents or using an extract fan.

“Condensation and the damage it causes to the homes of tenants remains a major headache for social housing providers” says Joanna Smith, Product Marketing Manager - Refurbishment at Vent-Axia. “Our new PoziDry units will help solve these problems, by offering discreet, continuously running ventilation that is incredibly low cost to install and run. It’s the ideal choice for properties where installation space is limited, but where effective ventilation, fabric protection and reduced carbon emissions are still top priorities”. 

The PoziDry is designed for out-of-sight loft installation and available to suit air volumes up to 50l/s or floor areas up to 150m2. For properties with no loft space, the PoziDry Compact is small enough to fit within a kitchen cupboard or other convenient location, meeting air volume requirements up to 34l/s or floor areas up to 100m2. Both units are available with or without a heater for comfort.

Following close consultation with housing providers, both units have been developed to include Vent-Axia’s latest DC motor technology and backward curved impeller fan arrangement. This delivers outstandingly high energy efficiency and reduced carbon emissions together with ultra-quiet operation when compared to ordinary intermittent fans.  For a PoziDry unit, running continuously (23 hours trickle / 1 hour boost), running costs for a typical dwelling are estimated to be just £3.09 annually – less than one penny per day.

Vent-Axia has also developed the PoziDry and PoziDry Compact to automatically take advantage of ‘solar gain’ by increasing ventilation airflow when the loft temperature is over 19Oc.

Both units are easy to install. The PoziDry is supplied in kit form complete with required ceiling diffuser, flexible duct and worm drive clips whilst the PoziDry Compact features a round to rectangular duct adaptor, and a choice of accessories to speed up fitting time. Each unit can then be set to operate at a choice of 2 to 6 pre-set speeds, appropriate to the size of the home. Both the PoziDry and PoziDry Compact are BEAB approved and supplied with a five year guarantee plus five year maintenance free EU4 filter as standard.

The PoziDry and PoziDry Compact are part of the Vent-Axia Lo-Carbon™ collection of energy saving ventilation solutions. The aim of the Lo-Carbon™ initiative is to offer the latest low carbon ventilation technology which is capable of significantly reducing building energy consumption and carbon emissions.
