Product Description
Passive Fixed Vent Kit – These are single room circular passive ventilators. They need no electricity, allowing fresh dry air in and stale humid air and moisture out. The units come with an environmental filter which fits in the external housing to reduce drafts and filter the incoming air. The unit has a telescopic tube system which can adjust for walls up to approx 375mm thick. Simply core drill a hole through the wall and fit the unit in place.
We sell lots of these to landlords who tell us they fit them behind radiators which stops tenants covering or blocking them up! We also sell them with the PIV units for use as an exhaust vent.
When installing the unit the internal louvre points upwards and the external louvre fitted with the filter points downwards.
