2021 | INDUSTRIAL VENTILATION Box-I EC Centrifugal fans in sound-insulated casing with EC motor Use Air flow: up to 11190 m³/h 3109 l/s Power: from 91 W INLINE FANS FOR RECTANGULAR DUCTS Supply and extract ventilation systems installed in various premises. For arranging energy-saving and controllable ventilation systems. Compatible with 300x150 up to 1000x500 mm rectangular air ducts. Noise level: from 29 dBA Design Speed control Atmospheric resistant galvanized steel casing. The casing is heat- and sound-insulated with the mineral wool. 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. The fan speed is controlled with a 0–10 V control signal from the following sources: • integrated or external speed controller • controller with sensors • central BMS system. 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. Motor 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. Mounting 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). When connecting the fans to the air ducts through the flexible anti-vibration connectors, as well as for sizes 600x300 and above, the fan must be secured to a mounting surface with supports, hanger brackets or brackets. While mounting provide enough space for accessing the cover for service operations.
