A friend of mine was having problems with his sand blaster clogging up from moister. He had tried all kinds of thing to help, but nothing work or was a lot of trouble. So gets a drive shaft (5'long+/-) drills holes in the yoke ends (1 on each) and taps them for air line couplings. Then just lays it on the shop floor. No more problems.
Since then other friends and myself have used the idea with no issues, One freind has a three buy garage with three employees,(a lot of air used) with no issues.
Just thought I'd share the idea.
