How AV Series Works
Compressed air flows through a small circular opening to generate a high velocity. This air expands, resulting in decreased pressure to provide vacuum levels up to 27.5"Hg. The vacuum port is perpendicular to the air supply.

Performance Considerations
for Minimal Air Usage

Vacuum Levels
Depends on the application,
High, Medium, or Low:

• Select an H Model when
maximum vacuum level is
required, 25-28"Hg

When lower vacuum levels
satisfy the requirement:

• Select an M Model for 15-20"Hg
• Select an L Model for 8-12"Hg

This results in a substantial reduction in air usage.

Vacuum Flow
Substantial vacuum flow is developed at low operating pressures when using
Models H, M or L.

• Initially the curves are very steep.
The operating pressure at 40-50 psi
provides maximum vacuum flow.

• Higher pressures do not increase the vacuum flow but will increase
air usage.


Selecting the minimum vacuum level and lowest operating pressure in the following applications
will minimize air usage:

• Leak Testing
• Labeling Machines
• Paper Feeding Systems
• Printing Presses
• Vacuum Chucks
• Sheet Metal Lifters
• Packaging Machinery
• Encapsulating
• Food Processing Machinery
• Air Sampling
• Dental Equipment
• Gas and Liquid Mixing
• Air Cooling
