Re: compressed air question

With a run that long I'd go with at least 2" pipe. With a smaller diameter you may run out of air even though the compressor & tank are large enough to supply it.

The great thing about a long run is that your air will be dry. Run it slightly uphill & put a drain at the low end.

And the guys are right about not using PVC but if you are burying the pipe I'd have no issue with it. I have about a 40' run of 2" PVC buried at my shop & have had no issues. If it were to blow no one is in danger. ( been under ground for about 15 years now)

The extra tank that Aussie recommends is a great idea also.
