Vacuum Generators: Adjustable E-Vac Holds Parts To Work Station

I’ve written before about the diversity of applications that EXAIR’s compressed air products can be used for – the Super Air Knife and the Line Vac come to mind – but of all the products in our catalog, none have a longer list of applications than the E-Vac Vacuum Generators:

While they're probably most popular for "pick and place" (as evidenced by our catalog photos) the EXAIR E-Vac's boast a wide variety of uses.

I had the pleasure of helping a customer specify a product another popular application recently: clamping and chucking.  This caller had a machining center with a vacuum table – if you’re unfamiliar, it looks like an air hockey table, and works like one too, only in reverse: instead of using blowing air through all those little holes out to “float” the puck on the surface, it pulls air in through them to pull the part down and hold it in place.

This was for a relatively small table surface…about 9″ x 14″…and some of the holes could be blocked, if smaller parts were to be held down.  It was originally equipped with an electrically driven vacuum pump, but it had seen better days, and a replacement was going to be a little pricey.  They already had compressed air running to the machine, and were keenly interested in something small, inexpensive, and with no moving parts – like the Adjustable E-Vac.

After some discussion of the specs on their vacuum pump, we provided a Model 840008M Adjustable E-Vac & Muffler.  This not only gives them the ability to easily change the vacuum level & flow for different sized parts, but it also has a larger throat than the In-Line E-Vacs, meaning it won’t get clogged by the finite amount of dust & small particulate that can make it through the vacuum table’s holes.

EXAIR has four sizes of Adjustable E-Vac Vacuum Generators in stock.

By my count, we’ve still got fourteen E-Vac applications that I haven’t discussed in a blog yet.  If you’ve got one that you’d like to talk about (and give me something to write about,) feel free to call me anytime.
