Legal compressors?

Yeah, I know its not the motor. I was typing too fast on that one.

I'm curious which one 254 uses. It's similar in appearance and size to the standard small Viar, but distinctly different.

Viair has a few options that comply with the rules:

We get the 90C as part of FIRST Choice, my team uses the 92C, and that 95C seems to have a different motor. Perhaps that's the 254 compressor?

R79
Compressed air on the ROBOT must be provided by one and only one compressor. Compressor specifications may not exceed nominal 12VDC, 1.05 cfm flow rate.

Pretty much any compressor that fits that criteria.

From what I see,

4.10.4 R77
The only pneumatic system items permitted on 2014 FRC ROBOTS include the items listed below.
A. Items available in the 2014 KOP,
[...]
J. Compressors compliant with R79.

Which is

4.10.6 R79
Compressed air on the ROBOT must be provided by one and only one compressor. Compressor specifications may
not exceed nominal 12VDC, 1.05 cfm flow rate.

So yes, you can use a different compressor, assuming it meets those specs.

However, I am more curious HOW you have gone through three compressors now, while the VIAIR may not be a workhorse of a compressor, it should last a lot longer then that. Are you running your compressors for extended periods of time without active cooling on them (A fan cooling the compressor head)?
