Air compressors and tanks

I have 2 questions. 1. i've noticed most air tanks are rated at 150psi yet most of the new style compressors are rated at 200psi? if my press switch is a 165/200 is this bad when the tank is rated for 150psi ? Also i have one viair 450 running my air system, im wanting to add a second one, but a buddy of mine has a 380 for sale cheap, its 200psi, my 450 is 150, is it ok to mix n match these comps ? Jason Missouri

My tanks and 450 compressors are both 150psi but I have a 145/175 pressure switch, been running that setup for a long time with no probs. Why not just get the 380 and run a 145/175 pressure switch for both compressors, kind of a happy medium in between, should work fine.

good call, that maybe easier solution. i was just concerned because of the diff in press ratings. i mean the 450 has been doing 200 in the tank now for 6 months no probs. I have an s10 and if you know how s10's are, they are always hard to get front end up so i like having the extra air, lol

Yeah, the 450's can do 200psi no prob but they are only warranted for 150psi use. Either way with a 175 or a 200 switch you should be fine.

I put a safety blow off valve on mine, every shop / home compressor I've ever seen has them!!And not many if any truck/car compressors!Your tank if were to rupture will be like small bomb!!

where did you put the blow off valve?..what part of the system?..before or after tanks compressor...etc. Anyone ever heard of a tank blowing up ?

i've run 300+ psi to those 150 tanks many times. ***kids don't do this at home*** and have never had a problem I used to run 200 psi on my last time with and york 210 EDC for about 2-3years Daily with no problems.

Ive ran 200 psi for probably 5 years, most tanks have a 150psi rating because its part of the DOT rating. But the bust pressure is usually around 600-750 depending on the tank and who manufacured them.

Most tanks have a 3x safety rating meaning if theyre rated at 150 they tend to explode around 450. Parker has a 6x rating on most products but im not sure about their tanks
