Using the smaller size ac vacuum pump.

yorled on Wed June 03, 2009 6:02 AM User is offline

Is there any one out there who have experienced using the smaller size ,say1.3, 1.6,or even a 2 cfm electrical 110vac AC vacuuum pump?
I would like to buy one but would want to know a few things before rushing into buy.(a) How long does it take to vacuum an ordinary size motor car effectively. (b)What are the advantages and disadvantages of using one of those?
Thanks in advance for a quick reply!!!

IMO you'd be fine with any of those when used on an auto system. The larger the cfm the quicker the evac. I know Tim sells a 1.5 as the smallest at his store.

Mastercool 3.0 single stage best bang for a buck.

Mastercool 90062-A 3.0 CFM

For a car A/C system a 1.5CFM vs a 3.0CFM is a very small difference. Maybe it would make a difference on the SUVS with rear A/C and extra capacity. How many cubic feet do you think a car A/C system holds? Probably under or around a CF, so there are only seconds to pull a full vacuum. A CF is a square box that is 1 foot on each side.

The 3 cfm posted is a great deal though, heh..too bad I have one.

I believe the final micron capacity is what matters.

Yes and NO. Micron ratings are done in a laboratory setting. So real world results may differ by a fair degree. Most pumps by known manufactures will achieve good results as most quality pumps will pull below the 1000 micron level needed to remove moisture. In our shop with 7.5 dual stage pumps we see a normal micron rating of around 250. Yet pump is rated at a 50 micron level.
