Systemair RVK – plastic centrifugal fans for circular ducts

The Systemair RVK duct-mounted centrifugal fans are fitted with impellers with backward-curved blades and external rotor motors. The Systemair RVK fans for circular ducts are made from glass-fibre-reinforced PP plastic. The Systemair RVK circular duct fans can be used in damp environments thanks to the high tightness of the casing and the IP44 protection rating of the terminal block.

The speed of Systemair RVK fans can be continuously controlled via a thyristor or a 5-step transformer. Motor protection against overheating is provided by integrated thermal switches with automatic restart. The fans are supplied with a mounting bracket for easier installation.
