From the 1960's till around 1980, air powered aspirators were standard equipment in garages and service stations that serviced auto air conditioners in the US.
(Can't say if this is true for other parts of the world)
Due to manditory recycling of freons, they are pretty much obsolete, now.
I picked one up for $5.oo at an old garage, took it home and tore apart the sheet metal housing to find a block of aluminum with three holes machined in it, pretty much identical to the mechanical drawing shown.
I dug in my box of old plumbing fittings (everyone has such a box, right :-) ? and found a brass needle type valve to give fine control the amount of air going into the device. On the outlet end, I screwed in a barbed fitting that allowed a 1/2" garden hose (about 6ft in length) to be slipped on. The female end of the garden hose was a good fit for a 3/4" lawn mower muffler to screw in. This reduced the noise level by 80% or so.
(Yes, they are loud !! )
A small , barbed fitting was screwed into the suction hole and some braided clear plastic line slipped on to run to a filter flask.
This has proved to be the best source of vacuum yet found for vacuum filtering.
One can open the needle valve, slightly and get just the right amount of suction to hold wet paper to the buchner. As filtering proceeds, one can open the air inlet valve, slowly, to get more vacuum in the flask, in the event that the paper begins to stop up.
The outlet (muffler end) of the hose is thrown to the back of the paint spay booth, cum, fume hood, so any flamable, stinky fumes go outside.
Never tried to use it as a distillation vacuum source.
IMHO, the vacuum would vary too much, not to mention the cost to run the compressor for long periods, noise, etc.
I could be wrong on that ?
I've been wrong before.
Occurs to me that the outlet hose could be stuffed to the bottom of a barrel of water or kitty litter to absorb odors, if needed ?
With the air inlet valve turned wide open, it pulls about 28"Hg on my air conditioning gauge, also, it keeps a 5 Hp air compressor running about 50% of the time. ( Sorry, thats not very precise :>(
