Conveying small to medium air volumes with high resistance, this fan is ideal for refurbishments and retrofitting due to its external installation. It offers optimum efficiency and low maintenance costs. The radial impellers are made of plastic and feature backward curved blades. There is a connection piece on the intake side for installation on ventilation ducts, along with an integrated sealing flap.

The motor is an EC motor with ball bearings, suitable for continuous operation and speed controllable. It includes thermal overload protection and has a protection class of IP X4. The electrical connection is made to a terminal strip in the housing.

Safety instructions indicate that the fan may only be operated if the contact protection of the impeller is guaranteed in accordance with DIN EN ISO 13857 for free-intake fans.
