PneumaticPlus PPF3-N02B Compressed Air Particulate Filter, 1/4" NPT (High Flow), 5 Micron, Poly Bowl, Manual Drain, Bracket

I used this in conjunction with a homemade compressor aftercooler and the result is incredible! So good, in fact, that I may have to purchase an automatic-draining unit because otherwise I have to stop what I'm doing and empty it constantly. It's completely full of water after 2-3 fill cycles. The idea here is to cool the air charge as quickly as possible, and as early as possible in the system. When you add an aftercooler and put the dryer between the cooler and tank, it helps to condense and remove the excess moisture long before it reaches the air hose. Since I've done this, I have ZERO moisture coming out of my air tools, and almost zero moisture draining out the bottom of the compressor tank. I have yet to run a paint gun on this setup, but will be doing so soon. For those wondering, the aftercooler setup is simple... a box fan, the largest cheapo transmission cooler I could find, a roll of 3/8 aluminum fuel line, some compression fittings, this dryer, and some creativity.

So far so good, bought these to keep water and possible oil out of my airbrush line from a 30 gal oiled compressor. I have the 1/2 post air compressor and the 1/4 at the terminal end. Had to purchase 1/2 in to 1/4 in reducer separately for the half inch model. Posted a pic for size comparison since seller failed to do so for some reason. I’m not sure if this was the issue that others have been complaining about with leaking but the 1/2 leaked from the release valve at first but once it fully pressurized and the rubber seal on the bottom fully seated, it’s now air tight. I tested it out in ~70% humidity, the filter first in line air felt a little moist from the release valve, the second seems completely dry and the air from the brush is completely dry. So I would say definitely worth the purchase. Summer time will be the real test though, will update then if they under-perform

What I don't like is the fact that the bowl does not screw on. All it has is an O'ring that seals the bowl to the metal housing . I just got it today and to be fair have not installed it yet. I got it because it is just a device to filter out small particles and trap moisture from getting into my few air tools. I have Passche units with a regulator and gauge which don't have the plastic cover over the bowl yet the bowls on the Passche units for air brushes have a thick O'ring and the bowl screws in place. That to me seems much better built. Outside of the regulator and gauge the Passche units bowl is larger has the same 5 micron filter and a much better drain. It is also a metal housing . I'm not sure about the air flow ratings with the regulator wide open or if it's restrictive since this model I just got is designed for no air flow restriction. I can see this as an add on for an air brush if your compressor has a regulator or as an add on after and air brush regulator like the Badger or Passche . My compressor has a regulator and I always used it to control the pressure before the air brush regulator even though the bowl and unit are rated for 135 PSI Max , My compressor only puts out 100 PSI . Once I figure out what the flow is on the Passche unit model R-75 I may use it instead . Basically I just don't like the bowl sealed by a thin O'ring held in place via the gray plastic cover, the bowl is the only outward force to seal the O'ring . I did read a few reviews that mentioned air leaks. The bowls shield is a good idea just in case the bowl ruptures. Not sure I may return it . It looks very similar to the one Ingersoll Rand offers just costs less.

The housing is very well built and solid. Mounts easily with bracket provided. The filter capacity is amazing and works very well at removing water. The water release does spray out in whatever direction you point your finger so take care as to where you want it to go. Very good value for the cost.

Well designed and no leaks. Has held up better than some of the other bigger name brand filters.

I bought a new compressor and always had issues with moisture in the lines. I had filters of all sorts but still moisture in the line. I decided to try this filter x 2 and added a new pressure regulator with filter as well. So 3 in-line filters with my new 10 gallon compressor (see review for HULK 10 GALLON) and NOT A DROP OF MOISTURE! These are great little filters, inexpensive and of vary high quality! Great product and price!

Replaced my leaky HF unit and I won't look back.

Works just fine as a pre filter for my system. I up sized to the 1/2 npt size to have plenty of capacity for water, this should hold close to a half cup. The threads were unusable on the outlet side, they were gritty, and tore up the thread sealant tape. The fitting only threaded in 2 turns before binding up. The inlet side was better, the fitting turned about 5 turns, and sealed up just fine. I took a NPT tap to the outlet, and got 2 more turns before the threads cleaned up, and all is well now. I would have expected this to be caught at the factory. The inlet cleaned up a little better with an extra half turn with the tap as well.

Works well. Easy to drain

Dry air from the time of install

Works great instead In inline with my air compressor

Item returned before use due to change of plan but initial impression was. - VERY NICE INDEED!

Clearly advertised in the item description, max input pressure 250psi. When I physically check the unit on the side of the bowl shield it says max pressure is 145psi. Needed the unit to get my compressor working, now I have to go and search for another suitable unit. What a waste of time and effort. Going straight back for a refund. One star due to incorrect / misleading specifications.
