Product Description
Driven by AC power, this External Rotor Motor Cooling Fan follows dual side dynamic balance based technology. Spray treated surface of the rotor, flan blade and grid of this cooling fan is oxidation proof and corrosion protected. With having standard insulation level, this fan uses three phase or single phase motor having different voltage levels. The housing part of this fan is made of galvanized steel sheet with rust proof surface coating. The blades of this fan are connected with the rotor of its motor via welding process. Its motor is impedance proof and has thermal protection arrangement.
