compressor questions

[rtinniste]

Picked up a new compressor for the garage over the weekend to finally be able to run my blast cabinet.
Ended up scoring it at habitat for humanity for $250, ciason 80 gallon, 5hp, 22 cfm, two stage pump, single phase, 175psi, with auto shut off. Called ciasons with the serial number it was built in 2004 and its a $3000 compressor.

Only down side is the building didn't have 220 so its untested so I took the gamble.

But I don't know anything when it comes to compressors all I know is its more then enough to run anything in my garage so a couple really stupid questions.

*Being that its built in 04, came from so cal, has no visible dents cracks etc and some minor rust from what i can tell, should I be worried this damn thing is going to explode?
Seeing this has scared the hell out of me http://www.mytractorforum.com/46-saf...ilure.html

*Then off the pump what is the item circled in red I tried googling it but cant come up with anything. Air bleed for the piston when the its in the down stroke? Crank case vent?



I need to add another breaker to my box and run the conduit to the other side of my garage, plumb the garage with copper line and water traps, add a ball valve for the water drain, and change the oil, check the pressure relief.
