Roots blower mainly by the chassis, exhaust fan, cover, impeller, import and export muffler, such as the four major components. The chassis is mainly used to support the wallboard, impeller, muffler and fixed role. Cover is used to connect the case and the impeller, and made the rotation of the impeller, and play the effect of the end seal. Impeller is the rotation part of the Roots blower, divided into two leaves and three leaves, but because of the three leaves than the two leaves of the pulsation is small, lexternal rotor motor fan, smooth operation and many other advantages, has gradually replaced the two leaf Roots blower. The muffler is used to reduce the noise of the blower.

Roots blower conveyor media for cleaning air, clean gas, sulfur dioxide and other inert gas, special gas industry (gas, natural gas, biogas, carbon dioxide, sulfur dioxide, etc.) and high pressure conditions of choice for axial fan. In view of the above characteristics, which can be widely adapted to metallurgy, chemical, fertilizer, petrochemical, equipment, building materials industry.
