- Designation key
Supply and extract ventilation systems installed in commercial, office and other public or industrial premises.For arranging energy-saving and controllable ventilation systems. Compatible with 300x150 up to 1000x500 mm rectangular air ducts.
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.
Atmospheric resistant galvanized steel casing. The fan is rated for continuous operation always connected to power mains. Fitted with standard 20 mm connecting flanges for connection to rectangular air ducts. Access cover on the casing for inspection and maintenance operations.
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.
The fan is designed for mounting inside rectangular air ducts and can be installed in any position. The fan flanges are connected to the air ducts through the bolts inserted into the flange holes. Suitable for mounting into round duct on intake flange with a round flange reducer (available upon separate order). If flexible vibration-absorbing connectors are used to connect the fan to the air ducts provide their fixation to mounting structures with supports or brackets. While mounting provide enough space for accessing the cover for service operations.
