PIV

Positive Input Ventilation (PIV) is a tried and tested method of dealing with condensation and mould in the UK’s housing stock. It is estimated that PIV units have been installed in over one million homes since it was first introduced back in the 1970’s. Tens of thousands of PIV units continue to be installed every year and is often the first choice of ventilation for many landlords wishing to provide adequate ventilation for their tenants.

Leading British ventilation manufacturer Vent-Axia has put its Lo-Carbon PoziDry Pro™ Positive Input Ventilation (PIV) to the test in a real home environment. The PoziDry Pro was installed in a 3-bed home in Reading which suffered from an ongoing condensation and mould problem. Air quality data from before and after the PIV installation showed a sharp decline in both total volatile organic compound (VOC) levels and mould VOC levels after the system was installed, whilst also successfully tackling condensation and mould.

Airtech, the ventilation specialists, is supporting UK Radon Awareness Week (4-10 November 2019.) Run by the UK Radon Association, this year the campaign is focusing on recent research from Public Health England (PHE) and University College London (UCL) that reveals that home energy efficiency measures, such as double glazing and insulation, are linked to increasing indoor radon levels. This in turn is raising the risk of lung cancer caused by exposure to the gas. Since landlords have a Duty of Care under the Homes Act to provide a safe home, radon is therefore a major consideration for social housing providers.

Vent-Axia is delighted to announce that its ground-breaking Lo-Carbon PoziDry Compact Pro Positive Input Ventilation (PIV) unit has been announced as a finalist at The Electrical Industry Awards 2019. This innovative product combats condensation in mould even in the smallest of homes and has been shortlisted in the ‘Residential/Domestic Product of the Year’ category at these prestigious awards.

Offering a totally new way of thinking about Positive Input Ventilation (PIV), Vent-Axia’s innovative new Lo-Carbon PoziDry Compact Pro is the ideal solution for combating condensation and mould in problem properties without a loft. Ultra small and light, the unit can fit in the smallest of spaces and a removable inner cartridge makes installation and maintenance a breeze.
Vent-Axia has spent considerable R&D time thinking outside the box to come up with an innovative solution inside the box. The unique PoziDry Compact Pro has been designed to be the smallest on the market, making it easy to install even in the tiniest apartments. Half the size of conventional boxed PIV units the PoziDry Compact Pro is still powerful enough to effectively tackle condensation and mould. With the unit’s cross section measuring only 200mm by 200mm the PoziDry Compact Pro is so small that it can fit inside the decorative boxing that is used to cover its ducting.

The twin blight of condensation and mould causes damage to property and ill health for residents and can be an every-day problem for many housing association landlords.

Vent-Axia’s next generation PoziDry Pro™ Positive Input Ventilation (PIV) unit has been updated to include a Radon mode to help tackle the problem of radon gas in affected areas.
