150 PSI or 200 PSI

[roofingbloke]

I have a 63 on 6 & 7 bage with a five gallon tank, will be going with paddle valves, I seem to get different opinions on air pumps, i thought a single 150 psi viair 400 pump would be ok,

I have been told to stick with a 200 psi pump ??

Help me out guys.

Who is offering the advice? I have a single 150 and it works just fine.

The extra PSI gives you a little more time before the compressor has to come on and refill the tank. With manual valves I think a good 150 PSI compressor would be more than enough.

yeah, mine goes well above 200 but my pressure switch cuts off at 200 anyways. the higher the pressure, the faster the lift. if you don't care how quick it lifts, 150 should be cool. However, your compressor is going to run pretty much every time you hit a switch.

I have a 150 pressure switch right now, and will be switching to a 200 by the next time it sees the road. broey is right as the moment I hit a switch, the compressor kicks on...just more annoying than anything.

In case you care, this is from the ViAir page-

Product Notes

This air compressor is designed to handle up to a 5 gallon air tank. Using this compressor with a larger tank, pressure over 150 PSI, or without a pressure switch not only voids your warranty but may reduce the lifespan of your compressor.

Its not what people have told me but what i have seen, IE lots of 200 psi units,

So if a description for a compressor states 150 psi for a 5 gallon tank (maximum) then i am thinking this pump will be working to its maximum output,

So my thoughts were, I have a 5 gallon tank and a (150 psi regulator) 200 psi compressor will not have to work to its maximum output & as a result it should last longer,

You also want to check the duty cycle and CFM. Some 200 PSI units may pump more pressure, but take a longer time to get there. This will give you more time before the compressor comes on, but it will run longer. There are a lot of variables.

I think my pressure switch cuts off at 200 p.s.i and comes on at 145 p.s.i. but, the more p.s.i you have between max and min, the more you can play before your compressor comes on.

hey guys i dont mean to take over the thread but can most of the common air tanks handle 200 psi no problem?

yeah, I don't think I have ever seen an air tank that couldn't hold at least 200 p.s.i. the only thing I can recommend is if you buy a used one, look it over at all the ports and welds really really good.

thanks.reason i ask im buying an air tank local but they think its 150psi max operating.i have a 175psi switch.didnt think it would be a problem.

Most tanks I've seen are rated a 150psi. A friend of mine ran one at 400psi daily and never had a problem. My tank is rated at 150psi but I have tested it to 195psi with shop air and it held fine.
