New medium pressure compressor

Unread postAuthor: wdr0 » Sun Jun 17, 2018 9:31 am

Recently picked up this compressor for hybrids pre charge and large pneumatics. Not sure of the exact pressure capability but it is between 300/600 psi. 14 cfm, 7.5 hp. 2 stage piston, water cooled, oil lubed.

Have it stored right now but will get videos when I have a chance to clean up and fully test.

That's a beauty! Large pneumatics do pretty well at 150 psi, upping that to double or quadruple the amount would lead to some interesting results...

hehe that dog head will definitely need replacing, perhaps with a more modern filter.

Ha, I didn’t even notice the dog before. This was before I picked it up. Yes, electric, 440 volt 3 phase. I would swap the motor for single phase however it’s IEC so finding a single phase in that frame is highly unlikely.

Your motor current is going to be high, if you have 208v 1P 30-40mps, that will dim the lights :shock: 3P 20-25 amps.
You could go VFD :idea: more expense :(

I do have a vfd already actaully, as well as a 240-480 transformer. It’s just more to set up than if i has a single phase transformer. Then again, the compressor weighs 500 lbs so mobility is already pretty moot.

Ohh the current is not a worry. I’ve built the setup to run a 25hp motor and have a 200a service so aside from the slightly larger power bill not an issue.
