Benefits of Positive Input Ventilation

PIV systems help stop condensation and mould growth in new and existing homes by providing fresh filtered air from a central location in the home.

  • Eliminates condensation & mould growth

  • Stops streaming windows

  • No need for window vents if air-tightness is above Level 5

Health Benefits

With improved building features in our homes such as increased insulation and double/triple glazing, ‘natural ventilation’ is reduced.
A PIV system promotes free air circulation in the home, providing a significant improvement in the health of asthma sufferers and general indoor air quality.

Eliminates condensation, mould growth and musty odours

Poor ventilation causes streaming windows, musty odours, dampness, condensation, mould growth and excessive carbon dioxide in the home.
A PIV system provides whole home ventilation and condensation control, working to eliminate surface condensation, which causes mould growth.

Helps cut down your fuel bills

Warm air within the home accumulates at ceiling level, this air can be up to 7°C higher than the air at floor level. The PIV unit helps to redistribute this heat around the home and thus reduce space heating costs. Also, by installing a Positive Input Ventilation (PIV) system and providing fresh filtered air into the home, humid air is displaced without opening windows and thus making significant savings to the occupier.

Energy Efficient

Powered by an Ultra Low Watt Brushless DC Motor, the Axco positive ventilation units utilise the latest technology to ensure minimum energy consumption and long term trouble free life, achieving up to 80% more efficiency than a traditional AC fan.

L. Kirk, Ballyclare - Customer Review

"Couldn't have had better service from the moment I phoned until our PIV system was fixed. We had the PIV system for approximately 8 years (fitted by Housing Ex) and didn't realise just how good it was until it stopped working! Within 5 days of the PIV being off we had black spots starting in the bedrooms and lots of condensation on the windows. BEAM came out and fixed the system quickly and we have dry windows every morning and no more damp. Personally think that one of these systems should be fitted by all home owners and landlords."
