Harbor Freight 40211 Air Dryer is an exact match

5/5

Designed as an exact replacement for Harbor Freight model 40211. A problem with mine caused it to stop draining and after locating that it would take HF 10 weeks to send, I found it for only one-third of In every way, except for the casting imperfections and fittings, this is the same unit. You need to unscrew the original, pull out the hose mount from underneath, attach this one to that, then screw the new mount on.
