hrbor Freight vacum pump

> >

Sounds a little weak to me, but I am no physicist. It states it has a

10 Pascal maximum vacuum. Wikipedia says 1 psi = 6894 Pascal and my vacuum pulls about 10 psi. Must be a misprint somewhere or my oldtimers is kicking in.

Bruce, I agree with Gerald that this one looks a bit weak.

Usually, vacuum kits come with Gast pumps and Surplus Center has one for $30.00 less than the HF model you are looking at. The down side is it is

230volt.

I have one of these, hooked to a home built vacuum chuck (maybe $20.00 in the chuck) and it works like a champ. Deb

Bruce, The guys are right, this doesn't suck enough.. lol

Also, since it's for evacuating auto AC systems, I doubt that it's designed to run for extended periods, as you may need a vacuum chuck to do..

I'd really recommend talking to Bill Noble on these things, he's the expert..

Bill got me started with a used pump and a few accessories, and for a very reasonable price.. He's also "been there, done that", so he's very knowledgeable and helpful in this area.. YMWV

Thanks for the reply s. I saw the 120v and hoped. I don't have 220v in the garage, I mean workshop. I will take a look at Bills site, it was just wishful thinking.

Thanks aga> >

The pump I bought from Bill (a few years ago) is a 120v Gast that is fairly quiet and works really well.. I think at the time, he set me up with the pump, filter, vacuum gauge and a few other parts for about $200..

if it really moves 2.5 CFM it should be OK, though at the low end of what I would recommend - but this is a "real" vacuum pump and you do not need the high vacuum - I think you'd be better off with a thomas or gast wobble piston pump - 1/3 hp or larger should be fine - I have some on my web site (wbnoble.com) but I've heard that others are finding them locally - and that may well be cheaper. There is no price with the harbor fright ad that I saw - if it's over $100, then look elsewhere.
