Thanks for the input so far guys.
It's actually to run a gas booster pump, & the specs in my first post were given to me by the supplier.
I am looking at this compressor below, but it does not actually give the cfm of free air. The booster pump is very thirsty & it will drain the receiver in no time, so the size of the receiver is not an issue, the compressor will be running constantly for the time I am using it which will be only for periods of up to 30min no more than a couple of times a week. Would this be suitable, or do you know of a better one in this price range?
