Axco Loft Mounted Positive Input Ventilation (PIV)
An Axco loft mounted Positive Input Ventilation system gently ventilates the home by drawing fresh air from the roof space, delivering it to the property via the innovative diffuser.
Product Suitability
Improves Indoor Air Quality
Fresh, filtered air is constantly supplied into the home.
Suitable for New & Existing Homes
Easy to install and meets Building Control ventilation requirements.
Stops Streaming Windows
Moisture laden air is diluted and displaced through natural leakage points.
Improves Indoor Air Quality
Designed to run continuously, the loft mounted unit dilutes, displaces and replaces moisture laden air with fresh filtered air, forcing contaminants out of the property through natural cracks and leakages.
- Reduces condensation & mould
- No need for trickle vents
- Removes musty odours
Energy Efficient
The loft mounted PIV unit takes maximum advantage of the benefits of solar gain from within the loft space. Temperatures in the loft space are on average 3oC higher than outside, and as the loft mounted unit draws fresh air from the loft and delivers it into the property.
- Relative saving of around 150 Watts of heat energy per day
- Integral pre-heater tempers air when it drops below 10 degrees
- Ultra Low Watt brushless DC motor

Frequently Asked Questions
Here are some answers to your most frequently asked questions about our mechanical ventilation 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 – check out our top tips for reducing condensation in your home.
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).
Does the unit need serviced?
There are no service requirements for a PIV system, although we recommend changing the filter every 5 years.
