My 2 cents

Well I use SCBA tanks a 30 minute and a 45 Minute.

I have a small box compressor to top off a gun if needed but use a Yong Heng and 2 inline filters and a cyclone water seperator.
Have some pretty dry air.

The absolute best way out of the compressor dilemma is to have a buddy that’s a fireman. My two buds have unlimited dry breathing air at zero expense. They just bring full SCBA’s from work.
