Does anyone have the air filter & lubricator from Harbor Freight? I see that they have a unit on sale for $24.00 and wondered if it was any good. I want to install it on my compressor to keep the water away that accumulates in the tank. I had purchased new nail guns and don’t want the water to ruin them.

Appreciate all feedback.

Love my air tools too much. I run a DeVilbus Dryer system off the compressor. Keeps moisture out of paint guns, works on tools too.

Thanks Everyone,

I kind of thought that this wouldn’t be a good outfit for what I needed. I have too much invested in my nail guns to not protect them properly. So, I’ll definitely look into your suggestions.

John: I was looking at the same product, but … wasn’t sure of something … and … am STILL not sure:

I thought the filter was for after the tank, to keep the moisture out of your air tools.

The reason I didn’t buy it was … I didn’t get the feeling that it’s purpose was to keep water out of the tank.

Do you know? Does anybody?

What I saw, online, was this:

It seems there are things called … for example … Moisture Minder … that ARE designed to eliminate tank moisture, but … the ones that I’VE seen are frightfully expensive.

Hi Neil,

I’m looking to take the water out of the air lines after the tank before it reaches the nail guns. Also the same for the lubricator, it will be after the tank. When I use a blow nozzle, I notice that there’s a lot of moisture coming out. Seeing that, I would say that there’s probably rust from the tank as well. I’m guilty of not draining the tank as recommended, mainly due to the location and the fuss of reaching below the tank getting to the drain. I like your information for the drain on the bottom of the tank and just might implement that myself.

I almost bought the Harbor Freight unit, but decided to hear some feedback first. When I heard of leak issues, I’ve decided to keep looking for a decent, reasonably price unit instead. Right now, I’m just using air guns/nailers but plan on doing some spray varnishing in the future. So, I’m looking forward to hear from others on what they use.
