PR-CTA series roof type aspirators are manufactured from galvanized sheet and the body of the aspirator is painted with electrostatic powder paint. They are aspirators used in industrial facilities, kitchens and places that require high suction power, and that provide suction and discharge of the polluted air in the environment. The connection is established by stabbing the electric motor directly into the fan hub, and as a result of being equal to the fan speed, the desired flow can be achieved by using the frequency inverter by controlling the fan speed exactly proportionally.

The fan structure is backward curved and has sparse blades. Thanks to this structure, the blades are difficult to get dirty and easy to clean. The protection wires fixed around the blades prevent situations that may be exposed to fan movement. PR-CTA series roof type aspirators with high efficiency and compact design can be mounted vertically.
