How does this create vacuum with compressed air? Venturi affect?

If its a venturi wouldn't it use a huge volume of air?

Vacuum generator, AKA venturi.

Yes and yes.

Actually , they don't really use that much air . I've used a similar device
for pulling seams in solid surface countertops , and I was surprised how
little they used .

Yes and yes.

Yep. HF has a rather nice two stage vacuum pump which can run a vacuum
clamp fixture, vacuum former, etc.

Yes and yes.

Don't know about this clamp, but the similar device sold by HF for
removing moisture from A/C systems is quite noisy.

Of course! Sound cannot travel in a vacuum, so in order to create the
vacuum, all the sound has to be blasted out of the air.
It's simple physics, I am surprised you didn't know that.

I've seen larger clamping tables set up for use with a shop vac, same
with laminating bags. Easy enough to build one, just a box with a
plate of holes on top.

A lot depends on what you're laminating ... a shop vac isn't going to cut it
if you're vacuum forming/laminating three layers of 1/4" MDF to a radius
form .
Now if you're sucking a layer of fiberglass onto a canoe hull , it might
be just the ticket .

Per your latter,

It works well as long as you allow some air into the vacuum to cool it.
Otherwise the vacuum cleaner wont last long.

But that does reduce the pull...

Better vacuums don't use the 'sucked' air in the cooling path. Also
good because fines aren't blasted through the motor.

I always look for this feature when shop-vac shopping.
