In-Line E-Vac

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.

In-Line E-Vac Low Vacuum (Porous)

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 delicate materials. The low level vacuum prevents any warping, marring, dimpling or disfi guring of the surface due to excessive vacuum. Th is style generates more vacuum  flow to overcome porosity and leakage. There are 7 In-Line models that vary by flow and vacuum level.

In-Line E-Vac High Vacuum (Non-Porous)

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 sheet, and plastic. There are 7 In-Line models that vary by flow and vacuum level.

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).
