Exair 840008 E-Vac Adjustable Generator, 8.2 SCFM

Features:

• This small vacuum pump is ideal for a wide variety of pick and place, box opening, clamping, lifting, chucking, and surface mounting applications.
• The Adjustable E-Vac is maintenance free and has no moving parts to wear out.
• Engineered for high efficiency, this high vacuum pump minimizes compressed air use by allowing it to be tuned to the application
• With a simple turn of the venturi unit, the vacuum and flow levels can be changed to overcome porosity and increase or decrease the lifting power.

Applications:

• Pick and place of parts and equipment
• Bag / package opening
• Label placement
• Vacuum forming
• Mold evacuation
• Vacuum filling
• Leak testing
• Evacuate containers
• Clamping and chucking
• Paper alignment and feed in printing equipment
• Vacuum packaging
• Surface mounting
• Vacuum press for wood veneers and laminates
• Carton forming
• Robotic tooling
• Vacuum liquids for testing

Advantages:

• Easy to set the vacuum level required by the application
• Minimizes compressed air use
• Compact, portable
• No clog design passes dust, dirt, and contaminants straight through
• Single stage design eliminates fluctuations in vacuum
• Quiet
• Instantaneous vacuum
• Easy to mount at point of use
• Lightweight, rugged
• No moving parts - no maintenance
• Fast response - increases cycle time
• Durable 6061 aluminum construction
• Safe operation - no electricity

How it work:

• 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).
• The amount of vacuum flow can be adjusted. When facing the exhaust end, loosen the lock ring (turn counterclockwise), then turn the exhaust.
• To increase flow, turn the exhaust counterclockwise.
• To decrease flow, turn the exhaust clockwise.
• Be careful not to unthread the exhaust completely.
• There will be a point where no more vacuum flow can be achieved.
• The amount of vacuum created varies with the porosity of the load being picked up.
• Units come from the factory set to 15" Hg if used on a solid, non-porous surface.
• A maximum of 25" Hg can be achieved on a solid, non-porous surface, but will require increasing the air consumption and vacuum flow.
