Vintage Vacuum Pump Works. Unknown Brand and Model. 36 lbs
Tested and seems to work fine. In the vid I plug the intake and it pulls I'd say about 5 psi. The intake pressure is pretty light. I don't know how it's supposed to be. I plugged it into a home power strip and in about a minute it popped the strip breaker. Through a direct outlet it was fine. It does draw some power.
The rear of unit heats up after some time.
