KVR - Duct fan

Duct fan designed for installation in ventilation networks, featuring a compact galvanized steel casing with reduced length and 20 mm standard flanges for easy duct mounting. Supports both horizontal and vertical installation. Equipped with an efficiency-optimized impeller with backward-curved blades, driven by a voltage-controllable external rotor motor. Balanced to G6.3 (DIN/ISO 1940) standards, the fan includes a swing-out section for easy cleaning, making it suitable for slightly polluted air. The sealed motor has maintenance-free, lifetime-lubricated ball bearings, and protection is ensured by an integrated thermal contact requiring external wiring. Electrical connection via a casing-mounted terminal box.
