Dry air

[coltbean]

What kind of filter are you guys using on your air compressor for dry air? I've got a blasting cabinet and eventually want to do some painting but living in arkansas and it's high humidity are causing me issues with a normal filter regulator combo. I have a kobalt 60 gallon compressor.

Either get your self a refrigerated air dryer or a good desiccant filter. That should cover it.

Back 25 years ago when I was restoring a Mustang and doingalotofsandblasting, I made what I called a cool can. It consisted of a 5 gallon bucket and about 30 ft of copper tubing. coiled up the copper and put it in the bucket. drilled a hole near the bottom for the copper to exit and brazed quick disconnects on both ends. fill the bucket with water and use an air/oil seperator at the exit. still use it to this day and works really well.

I used a coupon and bought the plug in refrigerator one from Harbor Freight. It works great and seemed to have good reviews.

If you are running a blast cabinet, your 60gal compressor will be running 100% (or close to it) I would definitely go non-cycling refrigerated in the 15-20cfm range.

I am not filtering the incoming air to my compressor. I also have a Kobalt brand compressor, maybe a little larger tank. I ran out the tank's side fitting (using bushings to size down) with 3/4" copper pipe. Then up and at chest level soldered a T and put one air hose connector. Then went straight up the wall about 8'. Turned and ran about 30' to the front of the shop (making sure I had fall back to the compressor). Then down the wall to another T. Bottom of the T I extended and put a drain plug. Then came off the T to two fittings. One is for my 1/2" line for my 3/4" drive impact wrench. The other one has a filter assembly (stone filter type element and plastic water settling bowl). This arrangement seems to keep most of the condensation back in the compressor, which I open the bottom drain cock every so often to drain the tank. My blasting cabinet works good. But also, I have found I do not need full air pressure when using the cabinet. I have the air lever maybe half open.
I left the factory pressure valve assembly that is also at the top of the tank and if I want regulated air pressure I can use that. But since my spray gun has its own regulator, I rarely use the tank connector. Hope this helps.
