Air Venturi Vacuum Generator Pump for Vacuum Workholding, Fixturing & Clamping
The Air Venturi Vacuum Generator Pump is used for Vacuum Chuck workholding applications 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 using compressed air.
Each Air Venturi Vacuum has a straight through design which helps prevent
The Adjustable Air Venturi Vacuum Pump operates 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.
Straight through design prevents clogging by debris.
1/4" & 3/8" NPT - Air Venturi Vacuum Generator Pumps
Features of the Adjustable Air Venturi Vacuum Generator Pumps
- The Air Venturi Vacuum creates a vacuum using ordinary compressed air.
- Excellent for workholding, fixturing, and clamping applications using Vacuum Chucks, Custom Hold Down Fixturing, Suction Cups, etc.
- The straight through design helps prevent clogging from debris.
- Anodized Aluminum construction allows use in harsh dirty environments or clean rooms.
- Standard NPT connections for easy installation.
- Maximum vacuum generated is 22"HG - 26"HG (10.8psi-12.8psi).
- 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 70-80PSI air pressure is required to obtain the maximum vacuum.

1/4" NPT Air Venturi Vacuum Pump
This Venturi Vacuum uses a 1/4" No Clog Air Silencer (Catalog No. 10031). Order below.
3/8" NPT Air Venturi Vacuum Pump
This Venturi Vacuum uses a 3/8" No Clog Air Silencer (Catalog No. 10032). Order below.
A No-Clog Air Silencer/Muffler 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.

Work-holding / Fixturing calculations:
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 11.8psi = 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.
The maximum vacuum levels are obtained by rotating
the back end of the vacuum.
