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

 

 

 
An Integral Part of Your Product.
• Installations close to where the vacuum is required.
• No need to change the shape of your product. The vacuum sleeve fits directly into a machined cavity.
• O-rings are used for sealing vacuum and compressed air passages.
• Simply push in the vacuum inserts and install a retaingin plate.

 

 

 

How the IAV 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 suply. Material=brass.

 

 


 

 

 
 
 
     
 

How the ITD Series Works
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.


 

 

 

 

 
 

Vacuum Sleeves
Originally designed to provide a simple method to remove loose scrap from fabricating dies by converting compressed air into a vacuum. Twelve (12) sizes are available with vacuum passages ("A" diameter) from 3/16" to 2.0". these vacuum sleeves are recommended for applications that do not require high vacuum levels where the primary concern is the induced vacuum flow of atmospheric air through the system.

 


How Do Vacuum Sleeves Work
• 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.
• O-rings, which seal compressed air, allow liberal machining dimensions for installing Sleeves.

 

 

 

 

 
 

 

 
 

 

 
 


Performance Considerations for Minimal Air Usage
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, regulate the operating pressure.
• The graph shows typical Vacuum Flow curves for different size inserts.
• Note that all curves indicate the Vacuum Flow is quickly developed and has a steep slope for many different size inserts.
• 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.

 

 

 

Custom Vacuum Sleeve Inserts
• The AV Design allows us to build custom Vacuum Sleeves Inserts using the o-ring sealing method.
• When space is critical, vacuum inserts can be designed smaller in size to fit into the tightest locations.
• We have custom inserts without o-rings, press fits are used for assembling inserts and installation to seal vacuum and compressed air passages.
• Configuration of inserts is very flexible. Various materials are available.
