KVRI - Duct fan

Duct fan for ventilation networks with a compact, galvanized steel casing and sound-absorbing lining. Features 20 mm standard flanges for easy duct mounting and supports both horizontal and vertical installation. Equipped with a backward-curved impeller on an external rotor, driven by a voltage-controllable motor. The impeller and motor are balanced to G6.3 (DIN/ISO 1940) standards. A swing-out fan section allows easy cleaning, making it suitable for slightly polluted air. The closed motor design includes maintenance-free, lifetime-lubricated ball bearings and integrated thermal contact protection. Electrical connection is via a casing-mounted terminal box.
