Okay, 1st the negatives; (a) Am I fooled that this is a Wilkerson gauge setup ?? No. (b) Only in one port did I find some burrs that was not removed. (see 1st photo). Here's the time to add a basic common sense and logic statement. Any tool to be used as this will, needs to be taken completely apart and cleaned. Just as you do with a paint gun. (just read some of the 1 star "leaking" reviews of other similar products. I've read to many of the "I hooked it up and it leaked, I'm sending it back" ) ( or "taking it back" via HFT) Any little spec of dust, paint, hair etc., will cause a leak. If you zoom in on the rubber O ring in the 2nd picture, you'll see a couple specs of paint, probably fell off when I opened it. All this stuff is mass produced/assembled. (having had to support an assembly line for 7 years, it was amazing what we would find in the assemble fixtures. Food bits, hair, cut finger nails, bugs, sticky unknown liquids, etc., etc. and some of in a "clean room" !! ) Rant over, moving on. Now the positives; (a) Great price for an all metal construction. (b) At first, I was not a real big fan of the "wedge clamps/brackets" with the O rings pressed up against the bodies system that they used to assemble the units. With the 3 piece unit, (double dryer) it was just a touch to flexible for me. BUT, as you can see in the 3rd photo, they NPT tapped ALL ports, so you can just remove those wedge clamps/brackets and center O ring couplers and assemble the units with close nipples, as you can see one holding the two units together in the 2nd photo. Nice and solid. You just have to whip up a little setup to either reuse their brackets or make a new bracket, if you feel you need one. I have no air leaks, or water getting thru. A guy in another review explained how to clean the brass filters, so I won't rehash that. You can do for awhile, but eventually you'll probably need to replace them (especially if you ever drop a filter on on the cement floor, when cleaning it, ask me how I know this ) I contacted BLCH and they responded that they will be selling replacement parts on Amazon. Lets hope so. What's not to like ??!! ... show more

  • Working well so far
Size: AC2000-02
Easy to hook up and mount to the wall with a couple drywall screws. It's holding pressure with no leaks. I'll follow-up if it starts leaking or fails in any other way.

  • Works well for the money
Size: AC4000-04
Simple to install, works like it should, flow pattern was the opposite of my original so had to make a slight adjustment for that but otherwise no beefs..

  • Didn't work out of the box
Size: AC2000-02
The unit leaked out of the box Seems to be the pressure regulator section. Very unhappy

  • Works
Size: AC4000-04
I liked the setup of these for the way they sit on my compressor setup connection wise, no real pressure loss at 100psi, it allowed continuous use air flow around 90 or so which is plenty. Time will tell how long it all lasts.

  • Works great
Size: AC4000-04
I have this mounted to my wall in-line with my compressor and it works great. The first tank captures most of the moisture. The second tank gets the rest. Air pressure is great at the end of my line and I have zero moisture going into my tools/equipment.

  • Solidly Built, very nicely made, one small hiccup though
Size: AC3000-03
This really is as good as it looks! Very solidly built. Intriguing how it has a double water filtration system. Everything works as expected. It adjusts nicely. The air gauge works well. It's very nicely made. The only issue I have with it is once I remove the metal cage that protects the glass container, it comes off rather easily. However, there appears to be some sort of trick to get it back on. Sometimes it goes back on quite easily, and other times it might take me a minute or more to snap it back in place. It rotates back into position from the left or the right side, but something prevents it from going back without a hitch. Fortunately, I don't have to open the metal cage very often...like never. It's not needed to remove the metal cage for the normal operation, so I don't have any issues, and I won't penalize the review. ... show more

  • Information on PSI is not accurate, also received a dirty unit.
Size: AC3000-03
So I just received this product, now I am going to be fair based on what I am seeing right at the opening of the box, so you guys have a honest idea of what you are buying. So I purchased this to be installed in my shop for an air system to a C02 Laser that I am installing, I needed something to keep the air dry, I also have a YT channel where I film and review the products I use in my shop, this being one of the products I was going to add to my Co2 Laser adventure here is my review so far First Impressions Out of the Box, the product feels solid, with the all model body, it feels quality, great color combo with the cream and blue, and at the time of my purchase which was a couple days before this review the product I bought was the 3/8 model and it was an awesome buy at $42.99, 2 days after I purchased this product, I realized I needed the 1/2 inch NPT model and went to buy it so I could return this one and I was shocked at what I saw, 2 days later, and the day of this review the 3/8 NPT model is now priced at $79.60 and the 1/2 NOT was 99.60 ... with that being said, I sadly had to pass on it, why would I pay 79.60 for something I just literally paid 42.99 for? The 42.99 price was an amazing price for what it was. I can see a small increase but that was a jump. moving on......next thing was the product manual, it has me a bit worried, because it is very deceiving based on what the ad tells you here on amazon, saying it has a max pressure of 160 psi, but the manual and device clearly state 145 psi max, and not to exceed it, see pictures... if it was meant to be 160 psi then legally that's what should be on the device, right but nowhere did I see 160 psi anywhere, so please be be cautious if your running anything higher than 145 that your system doesn't turn into shrapnel or cause bodily harm from inaccurate information. Quality The unit I received looked like it was a used device or someone's return, it had black fingerprints, on the product, and also on the included manuals as pictures show. Another issue was also on the glass on one of the water separators it had a chip in it. I also noticed misspelling in the manual as well as shown. with all this being seen so far how it works will be my next review I will revise this once it s all connected and tested. I will also post a review video soon. Hopefully the company reaches out about my concerns, so far the reviews on this product have been awesome so hoping my experience is as well. ... show more
