Tangential blower QG030-353/14

airsingle-stagebearing

The generally small impeller diameter (30 to 65 mm) to impeller length (up to 2×300 mm) ratio permits an extremely shallow, flat design. The large intake and outlet cross-section makes it possible to achieve a high air throughput rate with low flow velocities. Further characteristic features of tangential blowers are a long air throw and extremely low running noise. Tangential blowers are available with an asymmetrical shaded-pole motor, a capacitor motor or a GreenTech EC motor with integrated commutation electronics (incl. tach output and PWM or analog input) to suit the application concerned. With the GreenTech EC motors it is possible to select a higher speed than for shaded-pole and capacitor motors, to overcome higher back pressures for example. Using appropriate sensors, the tangential blower featuring GreenTech EC technology automatically sets the required operating points and conveys the exact amount of air required. • Weight : 0.415 kg • Impeller material : Aluminum • Housing material : Aluminum, housing side parts made of plastic. • Direction of rotation : Clockwise, viewed toward rotor • Bearing : Motor with ball bearing system.
