Air Venturi Vacuum Generator Pumps: Anodized Aluminum & PTFE (Teflon)

Air Venturi Vacuum Generator Pump for Workholding, Fixturing and Clamping


The Air Venturi Vacuum Generator Pump is used for Vacuum Chuck workholding applications, solid or liquid materials transfer, and custom hold down fixturing applications. It can also be used as an AC Vacuum Pump to evacuate air conditioning systems.

The Air Venturi Vacuum 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.

These Air Venturi Vacuums have a filter free straight through filter free design which helps prevent clogging by debris.

Constructed in two materials: Anodized Aluminum, and PTFE (Teflon).

  • Excellent for workholding, fixturing, clamping applications (Vacuum Chucks, custom hold down fixturing, suction cups, etc.), and solid or liquid materials transfer.order below
  • Straight through, filter free design prevents clogging and passes materials, dirt, liquids, and contaminants.
  • Available in Solid Anodized Aluminum and PTFE (Teflon) which allows for use in harsh, dirty environments and clean rooms.
  • Anodized Aluminum Air Venturi Vacuums are available in standard NPT of 1/16", 1/8", 1/4", and 3/8" NPT, and 10-32 UN Connections.
  • PTFE (Teflon) Air Venturi Vacuums are available in standard NPT of 1/16", 1/8" and 1/4".
  • Maximum vacuum generated is 22"HG - 26"HG (10.8psi - 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.
  • See Workholding, Fixturing, and Hold Down Force Calculation Information.
  • See Vacuum Flow Data and Usage Tables.
  • A No-Clog Air 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. See Air Silencer/Venturi Vacuum cross reference.

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)

For example:
if you are using a 3" round suction cup to hold a part the force applied to the part is
7.069 x 11.8psi = 83lbs of holding force (For reference: 24"HG=11.8psi)
Where 7.069 is the area of the circle (πr2) = 3.14159 x 1.52

Remember to allow for a safety factor.

The typical supply air consumption rates and vacuum flow rates are listed in the tables below.
