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, BMS or Elta Fans DCV control. 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.
Specification
Casing
The robust 1.2mm galvanised mild steel sheet casing, is treated internally with a Class O rated (BS 476 Parts 6 and 7) fire resistant acoustic foam lining with a fire resistant polymeric coating. The wrap around folded casing is specially manufactured using integral motor mounting plates to provide additional rigidity for the casings. Each casing provides spigots to suit standard circular ducting. A removable lid is provided as a standard feature to facilitate ease of maintenance and cleaning.
Motors
The single range of units shall have an EC external rotor motor fitted as standard. The motor contains sealed for life bearings. Thermal Class of motors to THCL 130 or 155 dependent on size. All motors are suitable for use in ambient air conditions up to +60 ℃. Electrical connection shall be via an IP55 terminal box mounted on the side for easy customer connection.
Impellers
High efficiency low tonal noise backward curved centrifugal impeller. Dynamically balanced to ISO 14694 Grade G6.3 and directly drivenby the motor to provide a smooth airflow through the unit.
Control
Units shall be supplied with integrated commissioning controlallowing single speed selection and alsolimiting maximum speed if used with anexternal potentiometer.
Quality Management
Units are to be designed and manufactured with procedures as defined in BS EN ISO 9001. All Quietflow SQS units are to be tested to ISO 5801 (airside performance) and BS 848 Part 2 (sound performance).
