In-Line Vacuum Generator


These single stage, cylindrical units are compact and easy to mount at the point of use. They can be held in place by threading them dircetly onto compressed air line or with the use of a mounting clip. They are 7 models avaiable for use with porous materials, like cardboard, with vacuum levels up to 21" Hg (71 kPa) and vacuum flows up to 18.5 SCFM (524 SLPM). They are 7 models avaiable for use with non-porous materials such as glass, with vacuum levels up to 27" Hg (91 kPa) with vacuum flows up to 15.8 SCFM (447 SLPM).

How The In-Line E-Vac Works?

Compressed air flows through the inlet (1), then through a single directed nozzle (2). As the airstream exhausts, it expands and increases in velocity prior to passing through the venturi (3). A vacuum inlet tangential to the primary airflow (4) is located at the suction point between the orifice and the venturi. The airflow that is drawn through the vacuum inlet mixes with the primary airstream, then exhausts on the opposite end (5).

EXAIR manufactures two versions of the In-Line E-Vac, Low Vacuum and High Vacuum. The application will dictate which type of vacuum is most suitable.

Low Vacuum Generators For Porous Applications

Low vacuum units up to 21" Hg (71 kPa) with vacuum flows up to 18.5 SCFM (524 SLPM) are typically used for porous materials such as cardboard and delicated materials. The low level vacuum prevents any warping, marring, dimpling or disfiguring of the surface due to excessive vacuum. This style generates more vacuumflow to overcome porosity and leakage. There are 7 In-Line models that vary flow and vacuum level. Choose the E-Vac by the SCFM (SLPM) flow that best suits the performance needed for your application.

High Vacuum Generators For Non-Porous Applications

High Vacuum units up to 27" Hg (91 kPa) with vacuum flows up to 15.8 SCFM (447 SLPM) are typically used for non-porous materials such as glass, steel shet and plastic. There are 7 In-Line models that vary by flow and vacuum level. Choose the E-Vac by the SCFM (SLPM) flow that best suits the performance needed for your application.

Here are some sample of applications:

The In-Line E-Vac (porous version) is used to lift the plywood lid of a crate in receiving department.

 

The In-Line E-Vac (non-porous) is used to pick and place the plastic brick.
