The Anver Q-VDF series adjustable vacuum pumps feature a diffuser section which can be rotated by the user to control the compressed air flow and provide vacuum flow rates to 120 SCFM and vacuum levels to 25 in Hg. The vacuum pumps are suitable for handling porous materials and operating in dirty environments, because they allow debris to pass straight through their bodies.
The vacuum pumps have no moving parts and no gaskets or O-rings. They are available with barrel sizes from 0.1 in to 0.75 in I.D. Suitable applications include the pick-and-place handling of concrete block and packaging materials coated with fine powder and air-driven industrial vacuum cleaners.
