OB Air tank maintenance

Just picked up a hornblasters train horn kit from a buddy. However, other than having a obnoxiously loud horn I'm just as excited about having onboard air.

The system It came with is a 150psi 2 gallon Viair 20005 model.
The system is mounted directly behind my driver seat. I know the pumps can be sensitive to the elements and driving a open air jeep 100% of the year (I don't own any form of a full top and jeep is my DD) can't be good.

I was thinking about making a plexi glass box for it with holes on the side. This way it will keep the rain and dust away. Dose this sound like a good idea?
Also, is it bad to keep the tank full all the time? Is it best to drain it out when not in use? & I believe this pump has a air filter that is removable and can be cleaned. How often should I do this?

That set up includes the 280C Compressor. According to Viair that compressor is moisture resistant but not water proof. Here is the installation/owners manual for that air source set up. You can see that it shouldn't come in contact with water. That being said I have my 400C mounted under the hood of my TJ by the firewall. It definitely gets wet when driven in the rain but does not get dunked under water in any situation and it has been fine under there.

If you're going to build a box just make sure it has plenty of ventilation as the compressor will get very hot when you're using it. Good Luck!

you can leave the tank full, just put a petcock in the bottom so you can drain water out from time to time.

Depending on the tank you should consider treating the inside.
When I built the OBA bumper tank I torched the whole thing until it was to hot to touch all over so I was sure it was dry then I got some etching primer and let it get sucked into the cooling tank. It sucked up almost a quart of the stuff. Then I rolled and tumbled the tank so it got all coated inside. I let it sit overnight then blew out the tank with dried air for a couple of hours. Then I used an old freon vacum pump to draw in thinned out plasti-dip. Did the same tumble and roll then blow down /dry out. That was years ago with a lot of open air compressing between then and now. Even today when I open up the drain on it I get clear water, not a hint of orange rust.

how often should I drain my tank? there looks like a "petcock" on the bottom. Ive turned the compressor off and blew it to empty once or twice. If I do that on a normal basis (1se a week?) Should that help with keeping water out of the tank?

How often you drain the tank depends on how often the system is recharged and how humid the operating environment is. You should find out for yourself as it depends on your usage. A full air tank, sitting for days/weeks on end will not accumulate moisture.

Years ago, I ran an air compressor under heavy use inside a climate controlled room and often times would need to drain a gallon of water out every few days. Eventually, that same compressor was moved out into the dry Colorado air and I was lucky to get a cup of water out of it with similar use.
