Cabinet
The cabinet is made of impact-resistant plastic, the colour is white. The fan is equipped with electrically operated return louver. The flap opens at the same time as the fan is switched on. The model is equipped with operation lights.
Running wheel
The impeller is axial made of high quality impact resistant plastic. It has aerodynamically and performance optimized blades. The impeller is secured on the shaft by a central anti-slip screw.
Motor
The motor is asynchronous with auxiliary phase in the version with external rotor. The motor has grease-filled ball bearings for life. IPX4 protection, insulation class II. Double insulated design with thermal protection.
Flow direction
The flow direction is from impeller to stator, the flow can be changed with the REB 1R controller on the HV 300 AE model, with the CR 300 controller on the A model, and with the remote wireless control on the RC model.
Clamping system
The terminal box is accessible by removing the front grille of the fan. Connection is via a concealed or flush-mounted cable. The terminal block includes a relief clip to prevent the cable from being pulled out.
Noise
The table shows the sound pressure values at the point (B - Fig. measurement of acoustic parameters), at a distance of 3 m, for a mounted fan. The table shows the correction values to obtain the LWA sound power in the middle frequencies of the octave bands for the suction (A) and discharge.
Mounting
Mounting is carried out in a single or double glazed window with a thickness of 3 to 25 mm. Using 3 screws, the fan can be mounted as a wall fan for supply or extract air through the wall. Installation is possible in walls with a thickness of 25 to 300 mm.
Instructions
The fans are suitable for short ducts with very low pressure drop or for ventilation directly through a wall or window. Fans can be used for ventilation in residential construction, public rooms, offices, shops.
