Inline duct fan for supply and extract ventilation systems installed in various premises.
Direct mounting inside air ductworks.
For arranging energy-saving and controllable ventilation systems.
Compatible with Ø 100 to 315 mm round air ducts.
The casing is made of steel with a special polymer coating.
Aerodynamically shaped casing.
External terminal box for connection to power mains.
High-efficient direct current EC motor with external rotor and backward curved blades.
EC technology meets the up-to-date requirements to energy-saving and controllable ventilation and provides up to 35 % energy saving as compared to asynchronous motors.
EC motor ensures totally controllable speed range for the fan and has integrated overheating protection with automatic restart.
EC motor has no friction and wearing parts as capacitor und brushes. Instead a maintenance-free EC controller electronic circuit board is used.
The impeller is dynamically balanced.
The fan is compatible with 50 Hz and 60 Hz power mains and the maximum speed does not depend on power mains frequency.
The fan speed is controlled with a 0–10 V control signal from the following sources:
The control signal value changes depending on air temperature, pressure, smoke concentration and other parameters.
During signal value change the fan with EC motor correspondingly changes the rotations speed and delivers required air volume to the ventilation system.
The computer central building management systems (BMS) enable integration of several EC motors in network and precise individual operation control for each fan.
Any mounting position.
Fans are fixed to wall or ceiling with mounting brackets supplied as a standard.
Flexible air ducts are fixed on the fan spigots with clamps.
