dont air tools usually require at least 4-5 cfm @ 90 psi? i dont see how a compressor that small or tanks that small would be able to deliver for any amount of time...
i use a home contractor type compressor with a 6 gal tank, and on the compressor alone it wont run my IR gun, and using up all the air, i cant even shoot off 5 lug nuts without it having to turn back on and refill
IR is the best, i have an IR 3/8" and it has blown away lesser brands 1/2"
i have an ir 1/2" too
