Centrifugal Box Fan • Standard size 125 mm • Air volume flow rates up to 1.4 m%s • Static pressures up to 1055 Pa • Suitable for operating temperatures up to +60°C • Robust galvanised sheet steel casing • Available in EC Overview Acoustically lined single in-line centrifugal fans, suitable for internal duct mounting. The Quietflow incorporates advanced backward curved impellers, with three dimensional profiled blades. Features and Benefits 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 Integrated commissioning control allowing single speed selection and also limiting maximum speed if used with an external potentiometer. Efficient Performance High efficiency low tonal noise backward curved centrifugal impellers are directly driven by an EC external rotor motor, 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. Controllability EC motors provide precise speed control via potentiometer or BMS. Reduced fan speed can provide significant cost savings through lower energy consumption in both mechanical energy of motors and also on the conditioning of replacement air. Warranty Each SQS has a 12 month warranty.
