Were using the old compressor and were wondering if we can mount it upside down?

I know we have on experimental robots, but they never ran through a competition season. I don't see why not though.

Most compressors use internal oil to lubricate the workings. They depend on gravity to keep the oil at the bottom where it is needed. Thus, putting the compressor upside down is not be a good idea. And with a replacement cost of near $400, it might be expensive.
We had our compressor mounted upside down all of last year, (with very minimal usage as the only piston was a small 3/4" bore) but had no problems, if you do mount it upside down make sure to lock it in place or at least check the bolts often, as the vibrations and weight of the compressor tend to loosen them.
Note: Don't take my experience as a guarantee that it will work, because as stated we only used it for a single 2" stoke 3/4" bore that was fired maybe 10 times per match at most. As such, on time was minimal at best (other than on startup).
We ran our compressor upside down all last year all through competition season and two off season events without any problems at all.
For what I can see the old compressor is a Thomas WOB-L type, from my experience with the larger versions of these there should be no problem running them upside down.

You may run the compressor upside down but the rubber mounts are meant to be in compression. If you choose to isolate the compressor from the frame (recommended), you will need isolators that are designed for that use.

We had ours mounted upside down last year. No issues
