Products Fans Roof Type Units with Radial Fan 
RF-D series are high pressure and three phase roof aspirators that are being used at industrial plants, kitchens and at locations requiring high suction power and that enable suction and discharge of dirty air. The connection is established by directly placing the electric engine to the hub of fan, and the required flow rate can be set by controlling the rotation of fan as fully proportional through the use of frequency inverter.
The structure of fan is recurvate with rare blades. By this structure the contamination of blades is hard and their cleaning is easy. Protection wires fixed around the blades prevents the conditions that may be subjected to the movement of fan.
RF-D series roof type fans are being applied with optional sound absorbers. Roof type sound absorbers enable noise decrease of about 10dB(A) as per the model of product. It has been produced as compatible with the roof type fan to be assembled on kulis dimensions. The sub flange of sound absorber has been manufactured with eaves in order to prevent the areas of assembly to be affected by weather conditions, and its top flange has been protected as being placed within roof type fan. Moreover by increasing the strength of flange connections, the possibility of tumbling during storm has been decreased.
