Function
The vaned impeller and side channel face each other in a circular working chamber which is intersected between intake and discharge port. The rotation of the impeller causes a radial pressure rise in the cellular-shaped vanes which leads to a differing pressure distribution between the channel and impeller resulting in a rotational flow between channel and cellular vanes. The pressure generated by the vanes causes a further acceleration in the direction of rotation leading to a helical flow motion through the blower and a high pressure increase.
Side channel blowers are generally supplied as close coupled units with the balanced impellor mounted directly onto the motor shaft. There is no need for a gearbox or any lubrication. This makes the units quiet and vibration free in operation and virtually maintenance free.
A variety of drive options are available across the ranges including close coupled, belt driven and diesel engine. Acoustic hoods available for further noise reduction
Advantages
