Duct fan Kv 250L Wall model [8012948]

The KV series is designed as an exhaust fan for wall or ceiling installation. All KV fans have at least 25 mm long duct connections on the suction side. The FK duct connector enables easy installation and maintenance, and prevents vibrations from being transferred to the duct system. The fans have backward curved blades and external rotor motors. The shrouds are pressed from galvanized sheet steel. The fans meet the requirements of tightness class C. The fans can be used outdoors and in damp areas, provided that they rotate continuously at some speed. The fans are adjustable with a 5-step transformer. We do not recommend thyristor control. To prevent overheating, the motors of the KV 100 M and KV 125 M fans are impedance protected.
