Are the cheap vacuum pumps that need a compressor ok for home use?

rastoma on Thu June 17, 2010 8:02 PM User is offline

I'm not looking to get into the a/c repair business, but for a standard air conditioning system (not dual air, large trucks, etc.), are the cheap air vacuum pumps that require an air compressor suitable for a DIY'er at home?

I have a big post about an older car I'm trying to get the a/c working on, so once that is done, I may not need use of a vacuum pump for a couple/few years but if it does the job I'd just as soon have something like it on hand just in case.

That air-vac presents some huge problems.

It is too light for a boat anchor. Too bulky for a paperweight. It could be used for a doorstop, but only on interior doors. It needs a safety decal prohibiting it's use on exterior doors due to wind loads.

With a fair bit of work it could be cross sectioned to show how a venturi works for a high school physics class, something normally done with a printed page.

Nope, can't think of a single use for one. Sorry.

Air operated venturi pumps are not suitable. Buy, rent, or borrow a real vacuum pump.

Venturi vacuum works on the principle of blowing lots of air over a small hole, for MVAC work, you need a pump that is capable of going under 50 micons/Hg of a perfect vacuum, with these vacuum generators, you would be lucky to get within 101,600 micons/Hg of the required vacuum for MVAC. Even to get that, you will need a good air compressor at least 5 HP that will be beating itself to death in attempt to keep up running your electric bill way up.

They are incapable of doing the job correctly, and are reinvented the word, inefficiently, seeing a lot of crap on the market today ever since our government killed the FTC. Saw a super tiny shop vacuum on sale for 20 bucks that advertised 1.5 HP, what a lie. Or a AA battery operated operated stereo set capable of 300 watts output, or a pill on TV, no prescription needed that will cure every disease known to mankind, or I owed the IRS 160,000 bucks, after I called this toll free number, we settled for 160 bucks, yeah, sure.

It's like instead of of Washington cutting down on their BS, they spread it across the entire nation.

Did everyone not see j/k at the bottom of my last post?

j/k = just kidding

I was just responding to the overwhelming concensus that the pump I asked about was junk.

HECAT on Sat June 19, 2010 12:45 PM User is offline

I saw it but thought it was your signature/initials.

I guess we get too many sincere "I don't understand what your saying" responses to catch that your response was meant to be humor.

My daughter sends me text messages using all that shorthand stuff, don't know what the hell she is talking about, so have to call her back. Maybe I am too old and don't get this texting stuff, so much easier to talk to a person then to fool around with that super tiny keyboard. But I am told, they prefer to text rather than to talk to a person, I guess its okay if you are sending an address or a phone number when the receiver doesn't have a pencil. But in my weird way of thinking, if I don't want to talk to a person, sure wouldn't take the extra effort to text them!

I thought j/k was tossed around before cell phone texting was as popular as it is. I've seen it back in the bulletin board days before there was the internet where you had to dial up and connect to each bulletin board (forum) that you wanted to converse in.

if nothing else i think autozone rents vac pumps (rent as in "for free")

NickD on Tue June 22, 2010 11:52 AM User is offline

Based on that HT-6 Clutch Tool thread, that would be two round trips to AutoZone for me to break even for a vacuum pump.

Not sure if I would like to borrow a vacuum pump, don't know where its been.

Any thing I rented around here, had to repair it first while paying rent on it.

Also consider payback on tools, if you buy one of Tim's starter kits, not junk, the payback is with one job. Really can't find another endeavor where the payback is that quick.
