Default Harbor Freight # 97686 Desiccant Air Drier

Today, I had to run some errands, and ended up about a block away from Harbor freight. I went in looking for and found the model #97686, desiccant air drier, $40, and #97924 for the 2.2#bag of desiccant, $5. The drier is a 32" long piece of 2" pipe, with 2 removable baffles and about 24" of desiccant between them. The air enters in to a water trap, then flows thru the first baffle, up thru the desiccant, then thru the second baffle out of the drier. I bought this to run the air thru for the the plasma cutters. I've been using the smaller inline units, they work great, but don't last very long. Hopefully this will work, for what I got, I thought the price was very good.

Looks interesting! How do you change the desiccant? Could you draw it up so we can see how the baffles assembled?

how much is this advertised to flow?

I've got a sharpe dessicant dryer right now that I like - it gets the air VERY dry, but when hooked to my sandblast cabinet it seems like it gets bogged down quickly, I know part of this is the air supply up to the sharpe dryer, but the sharpe dryer has a sintered bronze element to keep the small dessicant particles out of the outlet hose, and I don't think it flows as well as it could.

Also, I'm curious if the mounting is required to be vertical? I don't have much free wall space in my shop.

200 degrees in the oven on a cookie sheet till the color changes back and you are good for reuse.Probably good for 3-4 hours of use before needing recharged ,at least that is all I get on the soda blaster.

I real sorry the attached picture is real crude

the 2 screw on caps, - Green
the main body, - black
the 2 baffles, - blue
the media area, the red between the baffles

to change the media, you unscrew the caps the baffles and media will come out. to reload, screw the bottom cap (with the drain) drop in the bottom baffle, load the media, install the top baffle, tighten top cap.

17 cfm @ 150 psi, the paperwork only talks about vertical mounting, probably because of the water trap.

Like Cutter, I avoid paint or painting at all cost, unless I can paint outdoors. I run the plasma cutters constantly, and got tired of using the inline desiccant filters, at about $7/ea, so I went to this. Keeping the moisture levels as low as possible is the best way to prolong plasma cutter consumable life. It can be used not only with the plasma cutters, but any other air tool or air operated equipment I have.
