Tank size or PSI consideration for sizing a portable compressor

by John O'Day
(Wi. Rapids, Wi. USA)

Bill,


I have tires that require 150psi pressure. I want to buy a portable compressor for this and other smaller needs. Should I buy a compressor with a 15 gallon tanks and 225psi capacity or a compressor with a 30 gallon tank and a 175psi capacity?.

I want a portable compressor so I can move it around to different locations.

Filling 150 PSI tires
by: Bill

Hi John. I've moved your question to another forum on this site.

As long as both compressors can deliver the PSI required, the tank size can be whichever you prefer since the tank size has little to do with the air pressure... except

Except for the issue of speed. You don't indicate the tire size so how much air will be needed per tire is a question the answer for will help you determine if the compressor has to run all the time, can fill the tire from a single tank of air after it's been filled and the compressor doesn't have to run again at all... it demands on the volume of air required.

The little comment about "other smaller needs" can be a bit of a trap, given that we don't know what they are, and some folks think that a small air drill, for example, will get enough air from a small air compressor.

If you would kindly navigate to the sitemap page on this site located here:

... and scroll down the page to the CFM section there will some guidance for you there, as well as the pages on buying a compressor, compressor sizing etc.
