Compressor tank

I've recently upgraded to an 8 gallon tank. I know it's good practice to drain the thing, but do you drain it after every session? What's the longest you'd keep air in the tank? I'm mainly worried about water/rust buildup.

I drain mine every time I use it. Doesn't cost anything and it's good preventive maintenance. I work in a cool, damp basement. Bleed off most of the air pressure, then open the drain plug and let the air blast the remaining moisture out.

I Would also advise to drain at the end of session, using the tank pressure to blow out any water / moisture. This will undoubtedly extend the life of the receiver & like has been said, it's free.

I build in my basement. I blow that air out after each session. I also open the drain after each session. Good Luck!!!

As said above but a moisture trap in line will also help.

Every time.

Replacement or repairs are the options.

It is a good idea to release the moisture as often as you can to protect the tank. I use a dessicant-style in-line dryer to keep moisture from my painting and emptying the tank prolongs the life of that as well.

That being said- Depending on where you live (I live in Utah- very dry) you may not see as much moisture as someone from Florida.

The moisture you get in your tank is condensed water vapor from the atmosphere and does not contain the metals and salts that tap water does. So that water is not as corrosive as what we typically observe with tap water.

I have a Craftsman compressor that my dad bought in 1973, I empty the tank once a month if i remember, and still no sign of rust today!

Thanks for the advice!
