The HR100W unit feature balanced ventilation with 70% heat recovery and provides control of condensation and odours.The units are through the wall, with a range of control and length options. Effectively controlling internal relative humidity.

Fresh pre-warmed air from the outside is continuously provided to the room with simultaneous extraction of stale, moist air.
