What is a Positive Input Ventilation (PIV) System?
Suitable for new builds & existing properties and apartments, this condensation control unit ventilates buildings by bringing filtered air in through a central location.
How a PIV System Works
The PIV unit draws fresh filtered air into the building and gently ventilates from a central position on the landing or central hallway. Stale, moisture-laden air is diluted, displaced and replaced with subtle fresh filtered air forcing contaminants out of the property through leakages or extract points in wet rooms (if applicable).
Benefits of Positive Input Ventilation
Improved indoor air quality
A PIV System constantly supplies clean, fresh, filtered air into the property, so there is no need to open windows which often allow dust and other pollutants inside.
Health benefits
A PIV system promotes free air circulation, providing a significant improvement in the health of asthma and allergy sufferers.
Eliminates condensation, mould & musty odours
A PIV system provides whole home ventilation and condensation control, working to eliminate surface condensation, which causes mould growth.
Help cut down your fuel bills
Warm air within properties 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.
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.

Frequently Asked Questions
Here are some answers to your most frequently asked questions about our Positive Input Ventilation (PIV) Systems.
How does a Positive Input Ventilation (PIV) System work?
A loft PIV unit draws air from the loft space and once passed through the filter on the unit, pushes the clean air into the house via a ceiling diffuser, typically located in a central location (I.e hallway or landing area). If you have a warm roofspace, an Airsource PIV unit may be required, which draws air in from outside.
Will a PIV System help with mould/condensation in my home?
A PIV system promotes free air circulation and eliminates or reduces surface condensation, which causes mould growth. However, you may need to take other steps to help reduce condensation.
What if my home doesn't have a loft space?
A Wall Mounted PIV is suitable for apartments/flats which do not have a loft space.
Is it expensive to run?
Because of the low energy fan inside, a PIV unit is inexpensive to run (approximately the equivalent of a 60w lightbulb).
