Customer Reviews

Adequate for home use, maybe A small and kind of flimsy regulator, I would not trust it to hold up under regular use. Good if you rarely use it and are looking to save money, but I would suggest spending a little more for something more heavy duty. It is not worth having to shut down a branch of your system, or render as portable compressor useless to save a couple bucks. 3Product failure (leaks) in less than one year of service UPDATE (changing review to 2 stars based on longevity): Less than one year after installing this regulator, it is leaking from within. Eventually, this leak causes the tank pressure to drop overnight (while the system is shut down), to around 40 PSI. Once the tank pressure gets down to about 40 PSI, the regulator stops leaking.My initial 5 star review below:My 30 gallon moderate CFM compressor has ever performed so well. Years back, when I first got my compressor, I used it for nailers and moderate blowing of debris.Now finding myself using many different tool types, I really noticed my air supply was lacking. Consistently I would only have the necessary volume of air for just the first couple of seconds of use. The volume apparently was post regulator within the copper plumbed supply lines to my shop. Once that was depleted, the OEM regulator simply failed at moving air.Replacing the OEM regulator with this unit has completely resolved my issue. No longer do any of my tools starve for air. 2Good performance and easily configurable for all orientations. I like this because of:1. Performance. In particular ability to deliver volume with less pressure drop than the 4 other regulators I tested. With the tank pressure set at 100PSI, I observed the output pressure drop as it delivered air to an air blower with the regulator set at 80 and then 60. The pressure drop with this relatively high flow was between 1/3 and 1/2 that of four other regulators I had available. One on a Porter Cable compressor, one on a Rolair compressor, a cheapo Harbor Freight unit, and another one I had lying around of unknown origin. I couldn't find published curves for this regulator (or any other small regulator for that matter), but it seems much better than the others I have.2. Configurability. It's a handy feature to be able to configure it any way round. The gauge comes off and can be attached on either side, either way up, so left to right flow, or right to left flow with the knob top or bottom are all possible.3. Build quality. Seems good. 5First rate design and construction This may well be the best regulator I've seen. If I have one complaint, it's that the gauge seems small. That's no surprise, though. It's integrated into the regulator, and the whole block is rather small. Even so, it's a small complaint. Everything is well-marked and legible, and I am most impressed with everything else about it.I use a 30-gallon, oil-lubricated automotive compressor to run an airbrush. This is probably overkill, but for 5 minutes of noise, I get 2-3 hours of quiet work time. Unfortunately, my compressor has been eating regulators at the rate of one a year, though the last one only lasted 2 months. They work fine at 40 lbs, and may even work well at higher pressures. But sooner or later, when I run the pressure up to 80 or 90 lbs to fill a tire, the thing fails. As you may know, a regulator usually costs $20 to $60. It's a bother.The regulators I've bought at the Big Box stores seem really cheap. Their performance has been lackluster with several pounds of pressure loss when I actually start spraying. I've had replacement regulators fail right out of the package, too. Not good! With respect to most of the actual failures, I've since learned that it is extremely important to raise and lower the pressure slowly - more slowly than I've been doing it. Raising and lowering the pressure too quickly puts undue stress on the springs and seals. But the pressure and quality issues are still a bother, and I still needed a new regulator. So, I chose this one because I-R is a respected brand, this looked well-made, and the price was right.I'm happy to report that this is an outstanding piece of hardware, and apparently bargain priced. Other sites want $40 to $50 for the same unit. First, this has a very handsome, modular design. Second, all the parts seem well-made and fit together nicely. To adjust the inner range band, you do need to carefully remove the front housing, It snaps off and reveals the gauge assembly. Then, you move the yellow arrows as desired to set your pressure range. You pop the housing back into place and all is good. If you want the pressure knob on top, you remove the housing, remove a couple screws, carefully turn the gauge assembly 180 degrees, replace the screws, and replace the housing. Done!Once installed, I found the regulator has very little pressure drift - maybe a pound or two. Very Happy! Visiting the I-R site, I found that the company recommends putting a dirt & water filter between the air source and the regulator. No stock consumer compressor I've seen has this, and I've noticed buildup of contaminants in a couple of my worn regulators. So, this seems prudent and I will soon install a good filter unit to better protect my regulator.I recommend this as a very good, bargain-priced replacement regulator. I expect this to perform better and last longer than any other regulator I've tried. I will try to post updates over time. Thanks for reading. 5No instructions and horrible, tiny gauge Works better than the OE one on my compressor. It did not however come with any instructions, it took some digging online to figure out that the knob is removable and that the lens/trim is as well. The main disadvantage to this regulator is the TINY numbering on the gauge. Do not rely on using the gauge, it can not be read at a glance. Plan on installing another gauge inline after this regulator.To remove the knob, first remove nut, then use a wrench to grab the threaded area and unscrew. This will allow you to install in tight area without clearance for the knob. You can also clean and service the internals.The cover around the dial is removable by simply pulling on the black plastic. This will allow you to adjust the indicators on the dial, or pop the lens back into place.-1 star for lack of instuctions-1 star for horrible gauge 3100% failure rate I have 4 of these setup on my shop air system so I could fine tune the air pressure at each station. The line pressure is 165 psi, and every single one starting leaking around the adjustment knob within a few month. I would steer clear. 1gauge and knob orientation can be easily customized. The back cover is held on with ... I want to clarify that the flow direction, gauge and knob orientation can be easily customized. The back cover is held on with 2 screws, the gauge cover merely pulls or prys off (the black cover with the clear lens)..then the gauge is held on with 2 screws. It can then be swapped to the other side allowing right to left flow. Be aware that there are 2 small o-rings that must be in place (one on each side directly in the center. I just installed it and so far am very pleased with the quality of this unit. Ingersoll-Rand can be reached at the phone number on the box for any technical assistance. I agree with others that there should be instructions included. 5After a month of using it, very pleased I purchased a new 60 gal compressor that operates at 155psi. 90% of the regulators I found were only rated to 150psi. I tried one of the 150psi regulators and it leaked....I was concerned that it would rupture and cause damage. I purchased this one and after a month of usage, I'm very pleased with it.What I Like:Rated to 300 psiFeels solidregulator control is on bottom, doesn't interfere with my shutoff valve on topWhat I don't like:Small print on gauge. It's a minor nuisance overall but need my bifocals to read itI would buy it again, I would recommend to a friend. 5Medium Size - High Quality - Great All Around But Very Small Dial High quality build and materials. Quality trusted brand. Feels very sturdy. Good size for a small semi-portable compressor. Combined with the matching water separator, it will make a great combination. Adjustment is smooth and the locking mechanism feels positive. My only complaint would be that the gauge is tiny. You'll need good eyesight, but I like how compact and protected it is, making it less vulnerable to damage if the compressor tips over in the truck bed.Follow Up After Installing: This is the best regulator I have ever owned on a compressor. Hands down. It is compact but very well made. The adjustment is smooth and easy to dial in to whatever pressure you want, from max pressure right down to 0 and all points in between. Very smooth and controlled, lets you be very precise. Maintains a consistent pressure wherever you set it. Fantastic! For the price and quality, it's a bargain. 5Leaking after 6 months Leaking after 6 months from around the adjustment knob. Not good! Ran my air compressor very hot, fortunately had just changed oil, which no appears to need changing again. I contacted Amazon about a replacement, they referred me to the manufacturer who was 100% non-responsive. 1
