Hey Guys______ The situation is this: I have a 12 volt compressor (Quick Air II), with a 7 gallon tank (manual says 5 should be max.), and a pressure valve that cut everything off at 115psi”s… So, the question is ____ after the initial full up of tank, the comp. shuts off, I start the airing up process and immediately after starting airing up the compressor goes on. What’s the purpose of the tank, if it’s playing catch up? Air is going from compressor to tank than to tires, correct, if so, what purpose does the tank serve in the airing up process, the reserve capacity is only used initially when stating off(for a second or two), and then, compressor still starts immediately. Then I continue to air up until all four tires are full. If the tank is playing catch-up, why have it? Why not run straight off the compressor??? I’m talking strictly air up, not tools. Also does the size of tank matter if I have let’s say a 2 ½ gallon capacity would that make the system more efficient??? ______ THANKS BAYRUNNER

Sounds normal, it just doesn't take much of a drop in pressure for the compressor to notice and kick in (probably around 100 PSI).

if you had a 4 or 5 gal tank i bet it wouldn't run as much, it takes a lot more air to keep a 7gal tank at 115 psi than it does to keep a 4 or 5 gal tank a t 115 psi with an engine that is rated for a 5 gal. compressors aren't made to run continuously, thats why they have a tank. it may take you a while but continuously running a compressor for long oeriods of time will fry it . my compressor in my garage very rarely kicks on, it's pretty big but yet the engine is matched to what i'm using the compressor for(mostly air tools), and the tank size. i just wanted to give some advice but honestly i dont think you will hurt any thing as long as you use it strictly for airing up. hope this was helpful!
