All Gazelle side channel blowers are equipped with a frequency converter. This motor allows speeds of 3000 to 6000 rpm resulting in very high differential pressures of the single-stage blowers. The advantage of this blower for the customer is that it automatically adapts to the required suction or pressure capacity; furthermore it maintains exactly the pre-set differential pressure even in cases of changing operating conditions. Therefore the maximum suction capacity is not definitive for the design of the blower type.
Gazelle side channel blowers are available in single- and two-a wide range of cut points stage versions. In vacuum operation they can achieve differential pressures of up to 380 mbar, in pressure operation of 530 mbar. Because of the integration of many safety precautions over-load of blowers and drive is not possible. This means that the blower itself reduces the speed if there is danger of thermal overload or of too much current consumption. There are no external safety devices such as motor safety switches, under- and overpressure safety valves.
