Low Noise Each unit is acoustically lined internally with Class O rated (BS 476 Parts 6 and 7) fire resistant acoustic foam lining minimising breakout noise levels

Easy Installation New multi-mount brackets allow easy mounting in a range of orientations.

Easy Commissioning Minimum and maximum ventilation rates as well as control settings can all be setup easily via the wall display provided. Settings can be loaded from one display copying settings between units quickly.

Constructed from a robust 1.2mm galvanised mild steel sheet casing. Each casing provides spigots to suit standard circular ducting. A removable lid is provided as standard to allow easy maintenance and cleaning.

Efficient Performance High efficiency low tonal noise backward curved centrifugal impellers are directly driven by EC external rotor motors, provide low specific fan powers and stepless speed control without tonal noise generation.

Weather Resistance Units can be weatherproofed in the factory to allow external installation
