- In detail
Duct axial flow counter rotating fans can be mounted in a duct in any position. Counter - rotating fans operating parameters are better than those of standard duct fans. Counter - rotating fan casings are made of high quality powder coated sheet steel. (Round flange dimensions comply with the ISO 13351 standard). Its rotors are made of die cast polypropylene (PPG) and are reinforced by glass fiber (paddles) and die cast aluminum (AL) (rotor hub). At higher demands to working environment, it's recommended to use vanes made of polyamide (PAG) reinforced with glass fibre or aluminium (for more strength and more resistance to high temperatures). 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. Motor protection degree is IP 66, insulation class is F.
The maximum operating temperature for counter rotating fans is 60 °C. On demand we can supply high temperature fans with opeating temperature up to 100 °C.
Ideal for production halls, inventory spaces, workshops, warehouses, engine rooms, refrigerated storages, etc.
