Roof Type Aspirator

 

 

Outside body of the roof type aspirator is entirely made of aluminum and DKP sheet, with the internal and external surfaces of the body is painted with electrostatic powder paint. In this type of aspirators, there are options of forward-curwed crowded blades and backward-curved apart blades.

Motor pivot is directly mounted on the fan hub, and the fan rotates at the motor speed. Since there are no equipments such as bearing, belt, pulley etc, it is an aspirator with long service life and easy to maintain.

Roof aspirators can be used at temperatures up to 80 °C . Since the fans are statically and dynamically in full balance, they run very smoothly, silently and without vibration. This aspirator type is ideal for forming air flows of low pressure close to natural draft in chimneys.

Manufacturing capacities range between 1.500 - 9.000 m³/h flow.

Both single-phase and three-phase electrical motors are used in the manufacturing (380V , 50Hz - 220V , 50Hz). Electric motors have IP54 or IP55 protection calass (in special situations, Ex-proof motors having necessary safety class can be used). When selection of electrical motor is to be made, fan pivot power is increased by 35% or 50% depending on the fan capacity. Speed control panels can be added optionally to roof aspirators in order to ensure operation with varying flow rates.
