Vacuum pump refers to the device that uses mechanical, physical, chemical or physicochemical methods to extract air from the pumped container to obtain vacuum. Generally speaking, a vacuum pump is a device for improving, producing, and maintaining vacuum in a confined space by various means. ATO offers you oilless diagragm vacuum pump and oil-sealed rotary vane vacuum pump to meet your different applications. The rotary vane vacuum pumps have 1 stage and 2 stage available. They have advantages of light weight, compact size, high efficiency and low noise.
