Do you drain the air tanks during post trip?

never drain if dryer is discharing at 120 psi like normal..ka pow wet spot on pavement...good idea change cartridge yearly...with an old rig u can park on hill and drain oil n water out tanks on an old n 14 cummins if air compressoir tanks you dead as fuel pump hooked to backside!

 

I drain mine if i been running in wet weather . And when its cold. Otherwise i drain them every once in awhile

 

Change the cartridge on a regular basis and you shouldn't have to worry about it.

Don't change the cartridge and you'll be in trouble.

I drain during the day when it's warm. It's usually too late at end of day. When it's cold and froze.

Another thing that I've been doing lately is disconnecting the 2 lines off the dryer and filling with that brake dryer alcohol. That'll last a month before things start acting up again. Winter time.

Summertime I drain twice a month.

 

Drain every time it comes out of a warm shop before it freezes in tanks .. In winter I drain when I go from cold weather to above freezing or in the morning if I idle.. For summer about twice a week or more often if moisture comes out..

 

Alcohol will put a wear and tear on the rubber in all valves eventually. By a new dryer and you won't have to add it.

 

Some companies are smart with maintenance.

Some, are just too stupid and ignorant.

 

Don't worry, in a truck without a airdryer your tank will produce about 3 gallons of mixed sludge overnight into a 5 gallon bucket. If the valves were left open to drain completely. Its just one of those things related to old iron that is worth someone's life to drain daily at the end of day so it will be ready for work next morning.

 

The old school rule was drain daily. Hardly no one I knew ever did, but that was the rule. Depending on the truck I drain mine when ever I think of it. In my freightliner, I see the cord and drain usually when I fuel up. In my Volvo I have to open the steps to get to drain. So I drain when I think about it usually once a month of when I'm going home for time off during the cold months. Best thing is to incorporate it into your pre trip and do daily. It only take a minute or two. No such thing as to often.
