Can this be done?

I know this is the wrong forum, but I'm still hoping someone can answer my compressor question that's posted in Tools of the Trade. Can you run two compressors in parallel to double the CFM? Obviously you can't double the pressure, but the CFM should be, right?

Good question gunner!

I would also like to know the answer to this question to. I am planning on getting another compressor and not for sure whether to tie them together, or have one in the back of the shop and one in the front.

Of course its true..... I'm the one who told you it works.... in THEORY!!

.

I still believe its based on the "theory" that both pressors must turn on and off at the same time and work together..... not ever at seperate times and join completly at the tanks. No regulator between them. That's just my feeling!!

Did you change your name Dennis???

Why don't one of you guys simply call a manufacturer of a compressor and ask?
They should know.

Yeah, I changed the nick. That's the one I use on the other forums, so I thought I'd be consistent.

I have seen multiple compressors in a production environment. They all fed into one tank. with their pressure switches set to the same psi they would come on at the same time. I guess if you didn't want that mutch initial load, you could have one kick in at 5 - 10 psi less. The bigger the tank the more compressed air is available. You still have to have to match the output of the compressors to the size of the tank. There are formulae for this, but I don't know them. You might search the web for this topic. TC

I REMEMBERING READING IN ONE OF KOSMOSKI'S PAINT BOOKS THAT USING TO COMPRESSORS TOGETHEER NOT ONLY WORKS BUT IS ALSO RECOMENDED. THAT WAY IF ONE OF THE COMPRESSORS FAILS THE SECOND CAN BE STILL USED TO OPERATE THE SHOP. THE ONLY THING IS THAT THE COMPRESSORS NEED TO BOTH KICK IN (RESTART) AT THE PSI. OTHERWISE THE ONE THAT STARTS AT THE LOWER PSI WILL ONLY KICK ON WHEN THERE IS NO PRESSURE IN THE SYSTEM (FOR EXAMPLE FIRST THING IN THE MORNING). I'M SURE THE PRESSURE SWITCH FOR THE ONE COMPRESSOR COULD EASILY BE WIRED TO THE SECOND COMPRESSOR. ALSO ANOTHER THING TO THINK ABOUT IS TO ENOUGH SHUTOFFS IN YOUR PIPING IN ORDER TO BE ABLE TO USE EITHER COMPRESSOR INDIVIDAULLY.
