Adjustable E-Vac Saves Coolant

But how exactly does an Adjustable E-Vac Vacuum Generator save coolant?  Isn’t that what the Chip Trapper Systems do?  (It is, and that’s been covered extensively here, here, and-my personal favorite-here.)

Our E-Vac Vacuum Generators are probably most commonly used in pick-and-place applications, in conjunction with our Vacuum Cups.

From a lightweight manual operation to an automated system with large or heavy objects, the EXAIR E-Vac Vacuum Generators can solve the application.

The Adjustable E-Vacs, however, have a unique feature – a relatively large throat diameter – that makes them well suited for suctioning up liquids.  And I recently had the pleasure of helping a caller with just such an application.  They make machinery for the automotive industry, and in one particular operation, coolant gets left behind in ‘pockets’ of a particularly unwieldy piece.  They can drain most of it at the machine, but what gets left behind in these pockets makes a real mess as it goes to the next fabrication point, and, although it’s a small amount in each pocket, it adds up to a finite amount of wasted coolant.  It’s not practical to use an electric shop vacuum, but an operator could easily use a handheld device to suck up these little puddles.

Enter the Adjustable E-Vac…with the wide throat diameter I mentioned above and compact design, they were able to install a short suction hose (via a threaded push-in connector) to the vacuum port, and a little longer discharge hose to the exhaust port, and they have a quick and easy, portable, maneuverable coolant transfer system.  Here’s a short video I made in the Demo Room, once upon a time, showing how it works:

Saving air.  Saving coolant.  Saving money and time, one compressed air application at a time.  If you have one you’d like to discuss, give me a call.
