The HR300 unit incorporates 2 specially developed mixed flow fans for low noise and efficiency, with up to 70% heat recovery. Effectively lowering internal relative humidity the HR300 unit controls condensation and eliminates mould growth. Designed for through the wall mounting.
Fresh, pre-warmed air from outside is continually provided to the room with simultaneous extraction of stale moist air and smells. Heat is transferred via a unique plastic heat exchanger from outgoing air to the fresh air supply with no cross contamination, maintaining internal temperatures and providing a fresh environment. The unit is fully controllable for speed using a small dedicated speed controller. Automatic ON/OFF control or switching to boost is easily achieved using sensors/timers e.g. humidistat. For summer operation the heatexchanger can be removed and replaced with a plastic divider board to provide positive cooling to rooms.
Available in three speeds: 20, 58 and 83 l/s. It is ideal for light commercial applications including function rooms, offices and classrooms.
The HR300 unit requires a 380mm x 280mm hole. Units should be level and square in the wall.The unit should be fitted so that it overhangs by minimum of 50mm on the inside, and a minimum of 70mm on the outside. An extension sleeve is available for walls up to 650mm thick.
