Air Operated Vacuum Generators: Air-Vac Engineering

Single Stage Vacuum Generators: TD & TDRH Series
Straight through vacuum passage allows material to pass directly through the pump with no reduction of vacuum flow. Ideal for transporting or conveying solid materials which is entrained in the vacuum flow of atmosphere air through the pump. Vacuum flow applications also include removal of air or other gasses from a process vessel, chamber, tank or some other closed systems. Vacuum levels to 24.5"Hg.

When choosing from the chart below:
"M" Generators produce MEDIUM vacuum levels with lower air usage
"L" Generators produce LOW vacuum levels with very low air usage

"A" diameter indicates the size of the straight through vacuum passage.
Diameters up to 5/16" for TD models and up to 2" for TDRH models.

How TD 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.

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.
