FTX heat-recovery units

An FTX heat-recovery unit reclaims heat from the stale extract air and transfers it to the fresh supply air – so you no longer vent your heat out of the window. The result: lower heating bills, filtered pollen-free air and an even, comfortable temperature throughout the home. Our units are quiet, energy-efficient and easy to maintain, with built-in filters and humidity control – for houses and apartments alike.
