Rotary vane vacuum pumps are oil sealed pumps used for pumping clean, dry, non-reactive gases. Since oil is used as its sealant/lubricant the practical vacuum limitation for rotary vane vacuum pumps are around 5 Torr. These pumps are usually air-cooled, direct-drive 1750 rpm pumps with a small footprint for space savings. Choose from our one or two-Stage pumps, made by Travaini, Torr Vac, U.S. Vacuum Welch or Kinney. Pricing is very moderate given the vacuum they produce. With regular oil changes and periodic vane/filter changes rotary vane vacuum pumps have a better than average reliability.
