Using two

[johnnyfoos]

   My question-?

Lets consider that we are using a compressor
to per-compress air before  going into a high pressure pump.

   (shop air into a shoebox)

What if two compressors were hooked up going
 head to head with a check valve inlet to the shoebox
with both the compressors putting out the same volume and pressure.

 Will the pressure increase or will it be the same, ?
If increased, would we get both just adding together ?
    (100 psi + 100 psi = 200 psi)

  Or are going to be getting less like only a 50% increase
   (psi + psi = 150 psi)

 Just wondering if anybody here knows or has done it?


Thanks

You would have the 100psi, but double the volume.

Yes, same 100psi.  Theoretically, you'd have double the volume, but the Shoebox only uses a small volume (easily exceeded by one compressor), so it would do you no good to have them doubled up. 

If you wanted to double anything...  One compressor could run two Shoeboxes.

" Theoretically, you'd have double the volume,"
This is NOT for a shoebox set up, was just using that as an example.

So, maybe then if the two was hooked up in series we could get
an increase in pressure?

Well you would still only get the output of what the 2nd compressor in the "series" could output. Air pressure doesn't work like electricity.

Um? Compressors and tanks have relief valves on them to keep people from blowing themselves up. I don't thing that the tanks and seals on standard shop compressors would do well if you doubled the pressure.
