Axial Fans / wall-mounted / standard

Standard axial wall-mounted fans are fitted for wall-mounting in any position. Fan frames are produced from HIPS plastic (dia. 250-500) and amorphous ABS plastic (dia. 560-710) resistant to light and UV radiation (RAL 9017). There is a protection grid between the motor and rotor. Fan rotors are made from die-cast polypropylene (PPG) reinforced with glass fibre (vanes) or die-cast aluminium (AL) (rotor hub). Fan motors are asynchronous, single-phase 230V/50Hz or three-phase 400V/230V/50Hz. Single-phase motors are fitted for voltage-regulated rotational speed, while three-phase motors are regulated by means of a frequency inverter and are equipped with thermal overload protection in standard version. Protection grade for motors is IP 44 (0,04 – 0,09 kW) or 66 (other), isolation class F. The maximum working temperature is 40°C (0,04 – 0,09 kW) or 60°C (other). Fans are usually supplied in an exhaust version (A) – flow direction from motor to rotor. The  (B) version – supply version with a reverse flow direction – can be produced on request.
