I want ot use this between my compressor and tank** A: You may already know if you've gotten one, but on the instructions listed on mine it has 60c/140f as the max operating temperature. If you're looking to put this between the tank and the pump you'll want an after cooler in line before it. That way you're not exceeding that 140f. Hopefully this gives you a bit more to go on than the "don't do that" nonces who've chimed in with no real help. **Q: My compressor shuts off at 175 psi, what is the safety factor past 175psi? Is this still safe to use on a 2 stage compressor?** A: Yes it will work. I have a 60gal 2 stage Dewalt compressor that shutdown at 175psi and it works fine. I've been using it for over a year now with no issues. **Q: Can you drain the auto drain manually? I am in NY so it will freeze in the winter.** A: No, this unit has an internal float drain that will automatically drain out excess moisture once the internal float floats. You cannot drain manually unless you release pressure from your compressed air lines and removed the 1/4 turn bowl by hand and dumped out. You could connect a 110V timer drain to the bottom of the bowl and manually turn on your Timer drain to remove moisture from the bowl. Generally speaking, you would need the manual drain version in order to drain manually.
