Will connecting 2 air compressors to the same line increase my CFM (air flow rate) to run bigger tools?
Posted on October 29th, 2009 by admin
I have 2 small compressors in my garage which are both not up to the job of running tools like a die grinder (for long) or an impact wrench. If i was to connect them both to my main air line, would that increase my air flow rate and run the tools with a greater air consumption?
To connect the 2 compressor’s, the best way would be to connect them both to a receiver and then to your air line. This will give you double your volume of air, but if the compressor’s
are both governed to 60psi then this is the pressure you will get. The difference being the amount of air at your disposal will run an air tool that uses 60psi longer than using a single compressor. To achieve a greater pressure then the pressure at the compressor’s will need to be increased.

You will probably need one way valves first.

Should work.

Yup.
Die grinders use a lot of air. Even big air compressors have a hard time keeping up.

I would imagine that without a non-return valve on each line, before they are joined, you’ll blow at least one of them up.

i piggyback 2 compressors in my shop for running an air sander- all it does is increase the amount of air available so you can work longer- no check valve required- they will balance themselves out- to increase cfm, you need to increase supply line size- if youre using 1/4"hose, switch to 3/8"- that will run anything

As I see it, if you have 2 units pushing out say 60 lbs sq inch into the same line you still only have 60 lbs sq inch, but you will have a higher delivery volume. So basically this is not the answer to your problem. You need a bigger compressor with storage tank.
