Air Operated Vacuum Generators: Air-Vac Engineering

IAV, ITD, VS, and Custom Design Concepts: Small Vacuum Sleeve Inserts

An Integral Part of Your Product.
Two Basic Designs to Fit Your Needs
• No need to change the shape of your product.
• Installations close to where the vacuum is required.
• Requires machining a simple cavity for accepting the Vacuum Sleeve Insert.
• O-rings are used for sealing vacuum and compressed air passages.
• Simply push in the vacuum inserts and install a retaining plate.

IAV Series Design Concept
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 suply. Material: brass.

Pressure: psi
Vacuum Force: "Hg
Vacuum Flow: scfm
Air Consumption: scfm

ITD Series Design Concept
Compressed air flows through a small annular opening to generate a high velocity. This air expands into an unobstructed vacuum passage allowing solid material to flow through the pump with no decrease in vacuum flow. Material=black oxide steel.

Pressure: psi
Vacuum Force: "Hg
Vacuum Flow: scfm
Air Consumption: scfm

VS Series Design Concept
• Compressed air is forced to flow through the circular orifice, creating the required vacuum.
• The center chamber is the vacuum passage and allows removal of solid materials which passes through the Vacuum Sleeve without disrupting the vacuum flow.
Material: Black oxide steel.

VS Vacuum Sleeves
Originally designed to provide a simple method to remove loose scrap from fabricating dies by converting compressed air into a vacuum.

VS Vacuum Sleeves
VS Vacuum Sleeves are recommended for applications that do not require high vacuum levels but where the primary concern
is the induced vacuum flow of atmospheric air through the system. Eight (8) sizes are available with vacuum passages
("A" diameter) from 3/16" to 2.0".

Pressure: psi
Vacuum Force: "Hg
Vacuum Flow: scfm
Air Consumption: scfm

Performance Considerations for Minimal Air Usage
Regulate the operating pressure when Vacuum Flow is the primary requirement, or for applications that do not require high vacuum levels but where the primary concern is the induced vacuum flow of atmospheric air through the system.

• The graph shows typical Vacuum Flow curves for most
of the small size inserts.
• Note that all curves indicate the Vacuum Flow is
quickly developed and has a steep slope.
• Lower pressures of 20-30 psi provides 70-80% of maximum flow and will minimize air usage.
• Maximum Vacuum Flow occurs at 40-60 psi.
