New medium pressure compressor

[wdr0]

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...

It is electric powered? Oh no wait, I see it's dog powered

I see it's dog powered

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 3P 20-25 amps.
You could go VFD more expense

[wdr0]

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.

[farcticox1]

That primary is still going to need the current

[wdr0]

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.
