Vacuums adjust to lift heavy and lightweight objects

EXAIR’s Adjustable E-Vac product is a series of low cost, compressed air powered vacuum generators where the vacuum and flow rates can be adjusted to suit the application requirements. The vacuum pumps are suitable for a wide variety of “pick-and-place,” box opening, clamping, lifting, chucking and surface mounting applications. They are maintenance free and have no moving parts to wear out.

Engineered for high efficiency, the Adjustable E-Vac minimizes compressed air use by allowing it to be tuned to the application. With a simple turn of the unit, the vacuum and flow levels can be changed to overcome porosity and increase or decrease the lifting power, the company says. The straight-through, single stage aluminum construction requires no vacuum filter and passes contaminants from dirty environments through the unit so there is no clogging or loss of suction.

Adjustable E-Vac is available in 4 sizes that have adjustable vacuum rates up to 25 in. Hg (85 kPa) and flow rates up to 81 SCFM (2294 SLPM). Kit configurations that include vacuum cups, fittings, tubing and a mounting clip are available.
