DeVilbiss 130525 QC3 Air Filter and Dryer

This is a pretty good unit for the price! I've had it for about a month now, I have it down stream of a DIY moisture trap I built going by misc designs online, so far no apparent moisture at the tools. It was easy to install, seems like filter changes will be easy as well, and seems very well built. I would recommend for someone in the same situation as me, just a DIYer who is wanting to get into some paint and body work. Check out the paint guns, as well from DeVilbiss!

Works very good! Can't complain, it dries the air. Easy to install.

This is a perfect drying system for my application, a small garage shop. The system has three stages to trap and contain oil, water and humidity. It includes a nice regulator, pressure gauge and shutoff valve. If your system is plumbed correctly it will work great. It's easy to service and lets you know when it is time to change the desiccant. I can spray paint and run my air tools without the worry of moisture damaging them, as well as, contamination from my air supply ruining my paint jobs.

This filter is amazing. I have a small set up where I paint and refinish engine bay components, interior trim pieces,etc. I always struggled with getting small craters or specks in the paint no matter how thoroughly I cleaned the parts. Now that this filter is inline there is nothing getting through to the gun except clean air and paint. No more dimples or garbage in the paint anymore. After the clear is applied I am done. No need for wet sanding the nibs out because there are none. This was the smartest $200 I've spent, and wish I had done it sooner.As I said, I run a small one man operation, so I can't speak to this unit on a large production scale. But for light duty use this is exactly what you need to keep the clean air flowing and paint coming out perfect.

This is a good drier as long as you can keep the dessicant cartridge attached to the top piece. When you first get it you MUST take off the top and be sure that the cartridge is attached firmly (with a butterfly nut that is supplied). When I got mine it was not attached at all and I sprayed a bunch of paint before I realized it. I am not the first who has had this problem I realized after reading more about it. Otherwise works well and is a good price.

I am new to auto painting and have been struggling with tiny pin holes or Fish Eyes in my clear coat. I have tried everything from taking extra time and care cleaning and preparing my work before paint. However, nothing seemed to fully correct the problem. I was running an oil/water separator and a filter but still not getting the results I wanted. After much research I decided to up my filtration and this is the unit I decided to go with. I had to spend a little more on the extra piping from the compressor to this unit (Min 25ft with water traps) but it was well worth it. My work is flawless now. I could have saved myself double the amount of this filter in paint if I would have installed this sooner. In addition, I did call Devilbiss customer support with a question and they were extremely helpful and friendly. It is nice to know that Devilbiss stands behind their products.

THis unit is a fantastic buy. I had been having problems all year with automotive paint and fisheyes. The small, single use filters were not enough, even though I already had a water seperator attached in line. The QCS has a very functional water seperator built in, along with a large quantity of dessicant. The closed filters make it easy to replace dessicant. Best of all, I like the shut off valve and air control. This way I can disconnect the air lines, and won't waste dessicant due to ambient air getting into the filter. The first two panels I painted came out perfect, with no fisheyes. This is a great buy!

The outlet of the regulator uses a 1/4" npsm male fitting. I wasn't able to find an npsm fitting to connect it to my compressed air line system. However, if the male npsm outlet fitting is unscrewed from the regulator itself, you will be left with 1/4" female NPT threads which can easily be connected with a 1/4" male NPT fitting.The white pipe putty that comes on the fittings leaked air on two of the connections. I took everything apart then wrapped all threads with Teflon tape. This sealed all of the connections that didn't come assembled from the factory.The fitting that goes into the regulator (installed from factory) leaked a small amount of air. I used vibratite green wicking thread sealant to seal that one up without disassembling it.The turning action on the regulator feels like it is grinding when the pressure is adjusted. I opened up the regulator to find rough threads in the regulator assembly. Hopefully, this will get smoother with use. For now the regulator action feels cheap but it works.I've run two 80 gal tanks of air through it. So far so good with no leaks.

Works as described! Very happy with it
