ARO C38121-600-VS Air Filter-Regulator-Lubricator Combination, 1/4" NPT

I have used my compressor for sometime without a water separator. I reasoned that draining the tank would be all I needed. I was wrong. I soon grew frustrated with moisture coming out of my blow gun, putting moisture in my car tires (which causes damage to your wheels), and seeing moisture coming out of my pneumatic tools. So I purchased this all in one unit. It seemed a bit small when it arrived but it has proven to be a fantastic multipurpose device. It removes the water and any rust, dust, and other trash particles from the getting into the air hose. You simply push up on the valve on the bottom of the bowl to empty. I keep a bucket under the bowl valve to catch to water. The regulator on top is easy to set the desired hose pressure and to change it as needed and locks in place so you don't change it accidently. It is also easy to separate the lubricator from the water filter - which I did. Not all of my air needs needed tool oil in them. I installed a "T" fitting between them that allows me to install a hose fitting for filtered air without passing through the lubricator and then another hose fitting coming out of the lubricator for all my air tools. Adding a couple of shut off valves and simple release valves make it easier to refill the lubricator with oil without having to discharge the entire air system. I installed a second unit just like this one on my pneumatic lift and the lift works better than ever. If you use an air compressor at home or work I recommend you install this unit on it. You won't be disappointed, you'll enjoy your compressor more, and it will be a life saver for your air tools (they require dry, lubricated air).

Great quality combo Regulator, filter and lubricator. The connection between the two units is solid and they are reversible if your line goes from right to left instead of the "as shipped" left to right. It took me about 10 minutes to make the changes since I needed one of each. Currently have 2 in use with a rapidair system in my garage in conjunction w/ a Husky 60 gal. from Home Depot. As setup: compressor -> 3 ft. 1/2 goodyear whip -> shutoff valve -> to harbor freight regulator/filter combo. - > rapidair manifold. -> to two lines. -> each is split to the IR reg/filter/lube combo and then attached to the rapidair outlet. I'm also running a downtube at each branch for water management. combo appears to work well. I'm running about 115 psi at the tank regulator, and each IR reg combo runs about 90 psi, when active I get about a 5-10psi drop when running depending on the tool. the IR reg/filter/lube combo unit is the best i've seen on the market for the money. It feels solid and well made in stark contrast to the Harbor freight pile that's earlier in the system. Better than the harbor freight pile, cheaper than the Campbell Hausfeld from HD and appears to be higher quality. I'd recommend this unit over any of the other units. It costs more than some and less than others but it's the nicest out there.

I have a small machine shop. To start out I used regulators from RapidAir. I had three of them and all leaked around the plastic top and eventually around the water bowl. I run a 3/4 regulator at the compressor so the supply is 120psi regulated down to 100 at the machines. That shouldn't be high enough to cause the plastic tops to deform and leak but they did. I made an aluminum brace to better hold the plastic tops straight and that fixed the top leak. I never could get the bowl to stop leaking. New o-ring, good cleaning etc.. still leaked. I picked up two of these and So far they have been doing great. No leaks, the gauge seems accurate and the regulation is spot on. The added bonus of the air injector is great. My mill needed the extra lubrication as the tool changer gets cranky if I don't inject a little oil every once in a while. This saves me from having to bleed the air, disconnect the line and add the oil manually. Happy so far.

Worked well for about a year before developing a leak at the pressure regulator knob. Root cause was a torn diaphragm. Contacted manufacturer who diagnosed the issue and sent service kit (PN 104430 or 104431) free of charge/next day air. Product was out of warranty. Really happy with that. The service kit included a diahpragm, washer, spring, and plastic section with orings. Replacement was relatively straightforward, but instructions provided by manufacturer were a bit vague. The part that i was confused about what removing the top section. I thought that you needed to unbolt it from the inside, but the top just unscrews (i used a crescent wrench on the threaded top section, it did scratch the threaded portion a bit, but i don't use a locking nut on there anyways...) Other than that, pressure gauge is very small and pointers, which are used to mark compressor on/off pressures, are impossible to get at without removing a snap-fit cover, but you only have to do it once, if you bother. I dont use the oiler much, but it has worked when i have. The water drain is very easy to use, you can just push the rubber portion extending from the bowl off to whatever side is convenient. Oiler and water bowls are easy to remove, click securely into place, and seem well sealed (orings). Water bowl catches a surprising amount of water (i have to emtpy once every week or so of intermittent use). Overall, im happy with the product's performance and really happy with the customer service, but i do worry about its durability, specifically i worry that the new diaphragm night not last any longer than the last. Hopefully it was just a defective diaphragm. Will update if the repair fails.

Definitely happy with this purchase so far, as I have been with all of my IR products. Great for my use, and I certainly like the automatic tool oiler. Shortly after mounting and connecting this, I shut the supply line off to the regulator. I came out a few days later and noticed the gauge on the regulator was about 80psi instead of the 100psi I had set it to. I quickly thought, did someone change this or did it lose adjustment somehow… only to realize that the air supply was still off to it, and it still had retained that much pressure from 2 days earlier. To have a regulator with air drier and tool oiler, along with the removable bowls and adjustments that go along with that to only lose a few psi over a couple days was really impressing to me, and that was on a really small volume of air (about 3’ of supply hose). As soon as I reopened my supply line valve it went right back to where I had set it. GREAT PURCHASE! I’m very happy with the quality and value of products I get from IR! I will continue to purchase their quality products!

This product sure looks the part. I bought a similar product from HF years ago and noticed that the oil in the chamber never goes down-because it never worked. This product is very nice and works very well. The only thing I don't like about it ...OKAY two things that I do not like about it are lack of instructions even though this was NIB-just a bunch of safety information mumbo jumbo that has nothing to do with product explaination and the pressure guage is smaller than a cracker jack compass. It is really really small. Other than the 2 most important features of this device knowing what PSI or how to use the thing it is GREAT!

plastic water trap on regulator portion failed in 65 days, air pressures used are in the parameters of the manufacturer. I bought a name brand to not have issues with the regulator

Using this set taken apart for an on-board-air system in my truck. The oiler works perfect on the intake line in to my compressor, you can watch and adjust the drip rate in the little clear adjustment knob on top. I also have had no fluids of any kind make it throught the seperator/regulator. The gauge on the regulator is a bit small and hard to read, but once it's set who cares! P.s. these can be seperated, both have female 3/8 npt on inlet and outlet.

Very good

Works as expected. Fast delivery.

Used these in my shop. Set one at 90 psi, and 1 at 60 psi. They hold psi good.

Qualité prix ok
