Is this a low pressure compressor
Side view of this older compressor

We have this compressor that I'm told came from our 1950's era office building . It was mounted on a horizontal 40-60 gallon tank.


I was told it was used in a low pressure system of 25 psi ( perhaps the HVAC ?).

I was asked to see if this could be used in the repair shop at 125-150 psi.

I do not see anything with a brand name or model. There is a tag on the cylinder " 5-14-6"
and numbers stamped into the castings. 56C-02806 on the cylinder base and 650394 on the crank case. Numbers are not deeply stamped so I hope I got them correct.

Thank you for your assistance
