Axial Fans / ducted / standard

Standard ducted axial fans are fitted for mounting in  a duct in any position. Ducted fan housings are made from high quality powder-coated  steel sheets. (Dimensions of round flanges are consistent with the standard PN-ISO  13351). Fan rotors are made from die-cast polypropylene (PPG) reinforced with  glass fibre (vanes) and die-cast aluminium (AL) (rotor vanes). At higher  requirements related to working environment vanes made of polyamide (PAG)  reinforced with glass fibre or aluminium (higher resistance to high temperatures  and higher strength) are used. 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 66, isolation class F.  The maximum working temperature is 60°C. Furthermore, ducted fans can be  produced in PT version (higher working temperature).
