[AT] Worthington Compressor info needed

[Cecil Bearden]

Dennis:
Thanks.  I had a line on a Davey compressor 250cfm like I wanted, but I 
could not verify if it ran and the exhaust had not been covered...   It 
was an ex military one on a military trailer.... I have a bid on an 
Ingersoll that goes tomorrow, and is a lot closer to home.  I know it 
runs as I saw the you tube video....
I really would like to get a compressor that could be rebuilt at home 
rather than spending $5k and sending it in to be rebuilt...

This trailer unit looks like a portable unit used for running jack hammers and such. I looked at other websites and did not find much for parts.

Generally the vane compressors can be rebuilt by pulling and end cover, CLEANING, and then replacing the vanes. Sometimes the vanes are spring loaded, and other times there are no springs. If you have one good blade, you might be able to custom make blades for it if you could purchase some slightly larger blades for another unit and cut them down. In my experience, once a blade starts to fail, the failed pieces will hit the other blades and destroy all of the vanes within a few seconds.

I have designed some simple external un loaders to keep air moving when the discharge is stopped for some reason. This unit might have some internal unloader built in, but be sure it works before you do much with it.
