Product details
The HELI RR200B radial duct fan is a powerful ventilation system specifically designed for direct installation in duct systems. It is ideally suited for the transport of medium and small air volumes, even against high resistance. The fan housing is made of galvanized steel sheet and is equipped with round connection flanges that are compatible with standard ducts. The radial impeller features backward-curved blades made of plastic, contributing to high efficiency and quiet operation. The fan is driven by a maintenance-free single-phase AC external rotor motor, which is constructed in a closed design. The speed can be controlled by voltage reduction, and the fan is equipped with thermal contacts as well as sealed, low-noise ball bearings with long-term lubrication, enhancing the durability and efficiency of the device.
