Preferably 110, but I can rig up a 12 volt supply if necessary. Thoughts? When I was in college, the chem labs used a venturi on water faucets to create a vacuum for filtration. I've tried Google to show where to get them, and failed. Just a little attachment with a side barbed fitting ... good vacuum levels, CHEAP, and appropriate for one who utilizes Bernoulli in other ways ... now where do I get it? |

If you've got shop air, try looking for either a Vac Cubes or Piab venturi-type
vac injector. Both companies make some that are under 1" sq. and are used to pick up post cards, tec. on factory machines. Should be in the $20 range. You'll probably find them in your area at an industrial pneumatics supplier. Harry |
