DVB QC3 Air Filter Desiccant Refill is rated 3.8 out of 5 by 5.
Rated 4 out of 5 by from problem solved I was having moisture and water in my air lines. I bought a DeVilbiss QC3 filter dryer thinking it would solve my problem. It didn't. I had to replace the cartridge after every paint job so I contacted Eastwood and DeVilbiss. My filter set up was about a foot out of the compressor. They suggested I re-plumb my set up. I now have a 30' run with 2 filter drops coming off the top of the main line like they suggested. I also now have a 4" drop back to the compressor that will allow any water to flow back to the compressor. Problem Solved! I have done 3 paint jobs with this new set up and replacement cartridge with no problems and best of all my filter is still good. My paint jobs now are 100% free of contaminants with my new filter set up and the DVB QC3 filter dryer. I recommend this to every one. Great product. Now I have the correct set up. Thanks to Eastwood and DeVilbiss tech support for helping me work this problem out!

Rated 4 out of 5 by from Just what I needed The DVB QC3 Air Filter Desiccant Refill was the correct fit for my DiVilbiss system. It's cheaper from Eastwood than the place I bought it from the last time. I still think it's about 15.00 too high.

Rated 4 out of 5 by from DVB QC3 Air Filter Desiccant Refill A bit pricey, but to me well worth the investment. I have not had any moisture with my media blaster or my plasma cutter since I started using it.

I just bought the QC3 air dryer and it works great, I need to replace the cartridge and can not find the humidity indicator replacement anywhere can you help me???

Asked by: cobra
The replacement cartridge is all you will need. Once the old cartridge is taken out of the unit the humidity indicator will go back to normal until the cartridge needs to be changed again.
