Housing The fan casing is made of sheet steel, painted black, the mounting brackets and screws are electroplated. Impeller The fan impeller is made of thermoplastic fibreglass with a blade rotation of 32° or 34° as standard. The impeller is statically and dynamically balanced. Motor The motor is asynchronous with a stator equipped with cooling fins and painted black. It is equipped with grease-filled bearings for life and thermal protection of the windings. Operating temperature -40 C° to +70 C°. Insulation class F, protection class IP65. Speed control Speed control is carried out by frequency converters. Terminal block The terminal block is located on the fan motor and is made of black plastic. Installation The fan can be mounted in any position of the motor axis. The housing must not transmit mechanical stresses from the building structure. Direction of rotation The direction of rotation can be changed. With a standard impeller, the flow rate drops by approx. 30% when the direction of rotation is reversed. With the wall-mounted version, the standard air flow is from the motor to the impeller.
