filter for removing moisture from air supply

[Bob W.]

What do most people use to filter the moisture out of their compressed air supply? A supplier's URL would be very helpful. When I run my mill for extended lengths of time moisture gets in the line exen though I have two filters (down to .01 micron). Any help would be appreciated.

 

Thanks,

Bob

do you have a dryer on your air supply.

Not sure how small a water molecule is but I doubt that you will find a filter that would work.

I have seen a desiccant system that uses silica gel that absorbs water (those little packs in pill bottles that say do not eat).

I second the air dryer, I saw a cheap one here: Air Dryer

w.w. grainger also has air treatment products in their catalog plus diagrams , etc.

So is an air dryer necessary in the mill's air supply? I don't currently have one.

I would say if your area is humid you will need a dryer,We had trouble with air hoses blowing mist and the silencers on the air solenoids blew apart as the water could not get out in time.All that water in the lube system isn't good.We bought a small one and it works great.

You 'should' have an air dryer in your system. If you do not, cannot, whatever, you should look at a product from Reading Technologies called the 'Eliminizer' which can be mounted at the machine and will remove liquid water from the air.

Get yourself a dryer. Your not doing your machine any favors by blowing wet air through the spindle. Ingersol makes small units for around 700$ I think.

 

If it's for a home shop or you've got time and limited $$$, I've seen dryers made from a small fridge and lots of copper tubing. Suprisingly effective too.

The Harbour frieght one listed in Allens link in on sale til Monday and I just bought one...been using 2 fans "blowin" on compressor when running jig grinder and dessicant filters before grinder, so needed to do something and hopefully this works out, will still use one super speed fan blowin on compressor for high usage days as that really really cut down on condensation.(Dayton harbor frieght outlet had some in stock and "looks like a bargain")
