It's a Powerex, which is a susidary company of Campbell-Hausfeld.
If it's 5HP they came in two flavors; single stage two cylinder V and two stage. The single stage V puts out approximately 16 CFM @ 90 PSI. Not sure of the two stage output. The one in the photo looks like it's a 60 gallon...
Here's mine
It's 5 hp (25a @240v), 1725 rpm motor, 1000 rpm pump putting out 16cfm/90 psi. It has head unloaders connected to a pilot valve so it can run in a continuous mode.

Cycling the motor off and on more than 6 times an hour is what will shorten the life of your compressor (motor). If you want to run a longer session, and you don't have a compressor with a pilot valve and head unloaders, you can open the drain valve slightly to let some air escape and help keep...
In my experience most "real" 5hp compressors (motor at 20+ amps) will pump somewhere near 15cfm @ 90 psi or better. Any compressor pumping at 11/12 CFM @ 90 psi will have a motor rated at 15/16 amps @ 220/240v which is more like a 3/3.5 hp motor.
HF has two compressors that would do the job...
