Shadow, if what you refer to as the air filter port is the air INTAKE filter port, then the symptoms you describe are in line with an intake valve failing or failed.

Air puffs back out on the compression stroke as the intake valve doesn't seal properly.

That puzzles me a lot. "It throws glass out of it when I turn it on"?

What throws glass, and where is the glass coming from? Compressors don't have glass in them. The air gauges have a clear plastic face, but not glass that I know of.

I'd like to try to help, as would other readers, but we all need a bit more info about this compressor problem. You have me stumped, that's for sure.

Cheers,

Bill

It looks like small hunks of glass and shavings of glass.....maybe plastic....it comes out from the bottom of the compressor on top of the tank. It is a 6 hp 60 gal craftsman about 12 or 13 years old. It is a 5 ft upright tank. It is an oil free compressor.

You need to get a light to look at where the glass/plastic is coming from. Or, can you start a new thread and upload photos? We all want to see this. :-)
