Draining air compressor tank
I have a 60 gallon tank compressor and plan to use it occasionally in my home garage. How often should the tank be drained?
IS there any potential damage to be done if I leave moisture in the tank in freezing weather?
Thanks for your help.
To questions one, the answer is that it's best to drain the tank after every use.
To question two, there is potential for problems. Here's more info on draining the tank.
Draining the tank make a difference?

Bleeding (draining) the air - does it really make a difference if I use it one day
My dad yells at me for using the air compressor because some times I forget to drain the air.
He says ..." The second you are done filling the tire or what ever...You better drain it"! "If you don't the tank will get condensation inside and it wont work".
Is this true...does it really make a difference if I use it one day and go back to a full tank in a week or so....or do I need to drain it and refill it each and every time?
Please help!! I dont want to get yelled at any more!
Hi Lisa...I sure hope you don't get yelled at any more either.
Perhaps it might help if you understood where the water comes from? See the page: www.about-air-compressors.com/water.html for information about compressor water.
Essentially, as soon as the compressor motor starts and air is being compressed into the tank, water is appearing inside the tank too.
So, when you've finished the compressed air-using work, the tank has water in it.
Hopefully the air tanks on compressors are coated inside to help prevent water from getting to the metal and rusting it out.
Unfortunately, I'm not convinced this is the case, so if you don't drain the water out, it sits in the bottom of the tank, and wherever it touches bare metal, rust starts forming.
Over time the rusting of the tank will weaken it, and it's possible that a leak might develop, in which case it's time for a new tank.
Also, the presence of water in the compressed air tank means that this water will migrate down the air lines to your air tools. This is not good for them, and will, in time, create air tool problems that will have to be fixed.
All because of water.
Lisa, your Dad is right. You should drain the tank after every use. This is preventive maintenance to help make sure you air compressor tank lasts as long as possible and to help ensure that the minimal amount of compressor generated water migrates down the air lines to the air tools as possible.

should you leave air in idlle compresssor

Air left in compressor for two months while idle
Pierre, the ideal scenario is to open the tank drain to bleed off all air, and all the water that has accumulated in the tank during use, so that the tank is dry while in storage.
Else, your tank will rust.
Does that bother you? Is the fact that your tank might get a rust hole in it faster if you don't drain it than if you do important?
Only you can decide.
Me, I try to drain my tank regularly, and only leave air in it, if I'm using it the next day.
water generated inside a compressor tank
(Gauteng South Africa)
Are there different designs of air compressors that will allow less water out of the compressor and into the air line.
For example, is there some kind of device that is fitted inside some compressors, (I would assume more expensive compressors), that would retain more water inside the tank and therefore send less water into the piping system.
Is there a way of checking, or asking the salesman if his compressor will allow less water into the piping system.
John, simple answer... no!
The amount of water a compressor generates has to do with its operating temperature, the cycle time, the air temperature of the air that is being drawn into the compressor, and the relative humidity of that air.
If you have water in your air lines, install an electronic auto drain for the tank (that will get rid of the water in the tank) and adequate water filtration in the air lines to your applications.
See the pages on Water on this site for much more info.
