fusionx filter regulator

[txheat]

This regulator is releasing air on the bottom which is killing my compressor. Im guessing its dirty but i've never taken this apart.

Anybody knows the model number for this filter regulator for fusionx? All I can read is AW40-N.....Z
I search and came up several models. I need the correct number please.

If it's a self-draining water separator, there's probably a piece of trash in the seat. Turn off the air, the bowl unscrews, the self-draining valve comes apart fairly easily.
