Quietflow SQS250-1ECL - Centrifugal Box Fan

• Standard size 250 mm
• Air volume flow rates up to 0.347 m3/s
• Static pressures up to 841 Pa
• Suitable for operating temperatures up to +60℃
• Robust galvanised sheet steel casing
Acoustically lined single in-line centrifugal fans, suitable for internal duct mounting. The Quietflow incorporates advanced backward curved impellers, with three ndimensional profiled blades.

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.
