Shop Tip - Air Dryer

[velocity3x]

If you have a problem with wet, sloppy air in your shop air lines, this is an inexpensive solution I've used for used for 12 years. It WORKS very well! I purchase a Bendix AD9 air dryer at a "Big Rig" truck wrecking yard.....$25.00. Installed immediately after the air compressor, it removes 95% of moisture from the air system. It has only one moving part (spool valve with one o-ring). Unlike expensive refrigerated type air dryers....A "Big Rig" air dryer costs $0 to operate and it's cheap at wrecking yards. And unlike junk "spin" type air filters from Harbor freight, etc., this actually works!

Wow I never though of using that type.

and you are installing right after compressor to avoid moisture in the tank also correct? What pressure are these types typically rated at?

[velocity3x]

I don't know the rating , but big rig compressors can produce 150 psi.
