Roots vacuum Main features: 1, in a wide pressure range (1 ~ 1 × 10 4pa) have relatively the pumping speed. 2, the pump chamber without oil, to avoid contamination of the oil vapor vacuum system. 3, small vibration, low noise. 4, mechanical friction losses small Roots vacuum, so the drive power is small. 5, easy to maintain and repair, low cost, high life. The main features of Roots vacuum pumps: Roots pump 1. All specifications are cooled by air, without circulating cooling water system. 2. filling machine structure, no seal design eliminates failure points Hebei Roots vacuum uses a pump to improve Hebei Roots vacuum tightness price, more durable, high purity extraction / radioactive gas. 3. The inverter used in conjunction with a dedicated, can make a maximum pumping speed increased by 100%. The vertical flow horizontal flow easy to change.
