Roots blower characteristic form thanks to the structure of the inner rotor structure clover and reasonable at the inlet and outlet of the housing, so the fan blower direct vibration, low noise. Impeller and shaft for the overall structure and impeller wear, fan performance enduring, long-term continuous operation. Fan capacity utilization, high volumetric efficiency blower wholesale phone and compact, flexible installation. Bearing selection more reasonable, each bearing life even blower wholesale production, thus extending the life of the fan! Fans Viton seals made of imported materials, high temperature, wear and long life. Complete models to meet the needs of different users for different purposes. Intake and exhaust blower structure of a rectangular outlet structure - the traditional form, with two rectangular vents on the chassis, respectively, for the fan intake and exhaust purposes. 2, shaped vent structure - the design, manufacture are relatively simple, widely used. 3, pre-intake structure - slit open before the exhaust blower, pre-intake flow path through the high-pressure gas to the primitive import volume, so that the internal pressure reaches equilibrium with the exhaust pressure in advance, in order to reduce the impact strength of reflux and reduce noise.
