Thoughts on these?

I have a oil/water separator for particle removal down to 5 microns.
Do I need anything else? I see some other dessicant dryers down to 0.01 micron. Is that overkill?
Thanks Brian

Depends on your setup and use. If I were painting my own car I would want to ensure that the job went correctly with no contaminates fouling the job. I use some tp tools filters that go down to .02 microns.

For air tools and blasting, 5 microns would probably be sufficient.

The only issue with ebay items is replacement parts(filters). If you buy from a reputable company you will probably be able to get replacements and the items don't become throw-aways.

TCP Global I pretty reputable. I buy from them all the time for stuff. I have never recieved a bad product from them.

thanks

Moisture in your air tools is not a good thing either. It's amazing at how much water the tools spit out when the air has not had the moisture removed.
