Highly efficient polyamide fiberglass-reinforced have backward bent blades and belong to the type of "free wheels". These devices are used in centrifugal fans and have high aerodynamic characteristics with low power consumption and low noise level.
The impeller is mounted on an aluminum hub for easy mounting on the motor shaft. Galvanized steel inlet is supplied with the wheel.
Characteristics of the impellers were obtained in a specialized testing laboratory and correspond to DIN 24163 /BS 848 part 1 / ISO 5801 /AMCA 210 compactness 1, kg/m3.
