SRPS duct fans are designed to move air and other explosive gas mixtures.
The fans are installed directly into the rectangular duct of the systems and are used for both indoor and outdoor applications in temperate climates. The permissible temperature of the transported air is from -30 to +40°C. In standard version the fan is made of galvanised steel sheet. The fan impellers are statically and dynamically balanced. Fan diffusers are made of aluminium or fibreglass, electric motors are made of aluminium, copper, plastic alloys. Constant incoming inspection of materials ensures the reliability of the fan as a whole. Lightweight plastic impeller with backward curved blades, mounted directly on the shaft of an asynchronous three-phase electric motor. The fan design allows the motor to be cooled by the air flow during operation.
