Roots piston vacuum unit has remarkable energy saving effect, high vacuum degree, high vacuum interval large amount of air extraction, vacuum unit can be widely used in the power industry transformer, wire and cable, capacitor vacuum impregnation, vacuum drying process. Is vacuum coating, vacuum smelting, vacuum heat treatment, vacuum filter oil, freeze drying; The ideal vacuum equipment for aerial simulation test. If the suction contains a small amount of steam or dust gas, should be installed with a filter.
