The chassis of blowers casing is for Tri-lobe Roots Blowers, which is mentioned in the cases below. Its most important feature is the little change of low volume while the pressure is adjusted in a permitted range during the application process. In addition, there is a wide selection of operating point for pressure. What's more, it has no process of internal compression and the transmission of air is mandatory. Also, oil is not contained in the transmitting agents. The consistency of dynamic balance for rotor is high, and the overall vibration is low. Therefore, it operated with safety and reliability in a long term. Also, it is very convenient to maintain due to its compact structure. It possesses more advanced structure and higher machining efficiency with improved design. The function of Blower is to transmit the clean air, and it transmits the semi-water gas, water gas, sulfur dioxide, and other neutral gas under purification process as well. However,inflammable, explosive, toxic and highly corrosive agents are not permitted to transmit. It is widely applicable in economic sectors covering metallurgy,light industry, textile, coal, mechanical industry, electric power industry,petroleum, cement industry, chemical engineering industry, construction materials, environmental protection, paper making, sewage disposal, aquaculture industry, and pneumatic conveying.
