HV 230 M small axial fan

Cabinet

The cabinet is made of impact-resistant plastic, the colour is white. The fan is equipped with a return shutter, manually operated in the case of the M type, and electrically operated in the case of the AE, A and RC types at the same time when 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 sealed ball bearings with grease packing for life. IPX4 protection. Double insulated design with thermal protection.

Flow direction

Flow direction is from impeller to stator, flow can be changed by pull cord controller on M model, by controller on AE and A models, by remote wireless control on RC model.

Clamp-on control unit

The terminal box is accessible by removing the front fan grille. 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 gives the correction values to obtain the LWA sound power at the mid frequencies of the octave bands for the intake (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 and restaurants.
