No-Clog, Air Venturi Vacuum Pumps – Create a Vacuum Using Compressed Air
Filter Free Design Prevents Clogging, Easily Passes Liquids and Contaminants
Use Air Venturi Vacuum Pumps for Vacuum Chucks, Solid or Liquid Materials Transfer, Custom Hold Down Fixturing , and More
Air Venturi Vacuum Pumps – Create Vacuum w/ Shop Air
Air Venturi Vacuum Pumps are used for Vacuum Chuck workholding applications, solid or liquid materials transfer, and custom hold down fixturing and clamping applications. Venturi Vacuums are also used as an AC Vacuum Pump to evacuate air conditioning systems.
Air Venturi Vacuum Pumps creates a vacuum by supplying compressed air to the supply port. When air pressure is applied, the Air Venturi creates a vacuum at one end. The air is then exhausted out the other end.
The no-clog, straight through, filter free design prevents clogging and easily passes materials, dirt, liquids, and contaminants.
Available in Solid Anodized Aluminum and PTFE (Teflon); both materials allow for use in harsh, dirty environments and clean rooms.
- Maximum vacuum generated is 22″ HG – 26″ HG (10.8 psi – 12.8 psi).
- The Vacuum may be adjusted from 0″ HG to the maximum vacuum by loosening the locking nut and turning the exhaust end of the vacuum.
- Only 70-80 psi air pressure is required to obtain the maximum vacuum.
A Pneumatic, No-Clog Air Exhaust Muffler/Silencer can be used to reduce the noise level of the Air Venturi Vacuum. Tubing or hose may also be connected to the outlet port to redirect the exhaust air.

Hold Down Force / Workholding / Fixturing Calculations for Air Venturi Vacuums
Hold down force is calculated simply by: Force = (area of part being held in sq. in.) x (vacuum in psi)
If you are using a 3″ round suction cup to hold a part the force applied to the part is:
7.069 x 11.8 psi = 83 lbs. of holding force (For reference: 24″ HG=11.8 psi)
Where 7.069 is the area of the circle (πr2) = 3.14159 x 1.52
Remember to allow for a safety factor.
