PIV unit for flats & unvented attics

How does the Flatmaster PIV work?

The Flatmaster is an effective low cost solution to high condensation issues within flats, apartments and properties with no loft space. The positive input ventilation unit gently supplies fresh, filtered air into a home through a duct connected to outdoors. By slightly increasing the indoor air pressure the stale air inside the property is effectively 'pushed' out through gaps in the building fabric and trickle vents if fitted.

Unlike standard loft mounted PIV units the Flatmaster is designed to be wall hung inside the property. The physical unit is therefore more compact and designed to fit flush to the wall. Fresh air is pulled into the unit via either 100mm round ducting or 121x60mm box ducting connected to atmosphere, then fed into a central location within the property such as the hallway.

Health Benefits

Positive input ventilation has been clinically proven to help allergy and asthma sufferers by effectively removing high quantities of dust and particules from the air within your home. PIV units also help reduce and maintain radon gas levels.

Building Regulations

All Nuaire PIV units are compliant under Part F & L of the 2010 Building Regulations.

Unlike many PIV units the air filters inside the Flatmaster only require an inspection and clean every 1-2 years, normally with a vacuum cleaner and/or a hand wash. More frequent inspection post-building work is prudent as the filters are likely to pick up more dust than normal. Other than the filter inspection the PIV is a fit and forget item. All Nuaire units come with a 5 year warranty for added peace of mind.
