Brand: We all know this brand is one that delivers.

Build: Solid. Stocky. This would survive any reasonable drop test, or klutz kick test. It looks like Shop-Vac's larger mondo air mover, and this is well built. [UPDATE: I had this propped up high in the garage to get some air moving and, uhm, I swung around and made contact

I bought this blower to dry out our garage in the winter when snow melts off the cars and leaves puddles behind. It is now 5 years old and I can't believe how durable it has been. We run this blower 24x7 for at least 3-4 months each winter. Then, in the summer I discovered that I could place this in my basement blowing thru an unused

We live in the heart of coal country, because of how much coal is moved around in this area we’re shampooing the carpets of this 109 year old home often. Most of the soil in the home gets tracked in on the bottom of shoes.

So we bought this blower to help dry the carpets as we clean to avoid damaging the original slotted wood

As a hobbyist woodworker having fun and making items for the house or friends, any money I have to spare on tools and equipment is naturally going to go toward that new table saw rather than boring old dust control. I usually just ignore the tickle in my lungs (dust mask? what's that?) and blast my clothes clean with the air compressor at

I create a ton of dust in my shop so I purchased two of these bad boys. They are exactly what I was looking for! They control the dust in the air very well. Best part that's not even stated that when you buy more than one each comes with its own remote, however the remote will sync up to both units so you only have to use one remote at a

So far so good, will update with use.

* 4 Month update: It worked so well and it's cheap enough that I bought another one for the opposite side of my shop. Now my shop air is extra crisp and clean! Only annoying thing is I purchased the 2nd unit directly from WEN and it seems to be made differently externally and one of the

It took me awhile of searching to find a decent air compressor inlet filter that was usable. The cheap junk from China are sketchy at best and will break your compressor at worst. Don't get me started on the junk filters available. I could not find just the filter. I could only find the filter and housing. My HF filter was junk and so

This filter was a great find, and did quite the intake noise my 21 gal upright harbor freight compressor made. Of course compressors are loud that's just how it is but anyone who knows them knows how loud the intake can be and add a ton of extra noise with the air it sucks in and this filter sure enough makes a difference and gets rid of

This filter silencer got great reviews so I thought I'd try it on my Harbor Freight oil-lubricated 21-gallon compressor. Hardly a difference with this silencer, and if you search the reviews, other Harbor Freight compressor owners say the same thing. Regarding noise, it's probably safe to say that it's the compressor itself, not this

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

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

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,

Sturdy metal housing.

This is the best regulator that i've had the chance to use, it's accurate, maintains pressure and so far haven't had any issues with leaks. I am very pleased with this regulator. During the install I needed to reverse the filter and dryer to accommodate the piping in my garage and it was an extremely easy process to do so. The only

I really like this. I bought it to protect my pneumatic can crusher recently purchased. Any air powered tool needs filtered air and a little oil. The regulator holds great. I would buy it again.

I bought this to use on my Kobalt(Lowes) 60 gallon compressor. I had one of their(Kobalt)small 125psi regulators with the plastic knob to adjust air pressure and it leaked air and didn't catch any moisture. And the plastic turn-to-lock knob broke. It cost almost as much as this new one does.
This one is a heavy duty unit. No air

I needed to find one that went up to 175 PSI and this one does. I am glad I opted for the T Handle as this one is a little hard to twist. Relieves air as you set it and so far has worked flawlessly. I have a beast of a compressor in front of it as well. 7.5 HP ands 80 gallon tank. I do everything from sand blast to LVHP Painting. Would

This unit was worth the premium over the normal stuff. Fit and finish are excellent. I connected it to a large compressor with a high pressure whip hose in between. When not in use, it holds the pressure indefinitely without any loss. No more surprise compressor starts due to slow air

I did not want to spend $80 for an Iwata brand regulator/water separator, so I thought I would try this one. Using the included thread sealing tape, I installed the included pressure gauge and the two 1/4 inch NPT nipples. I hooked up my hose lines and attached it to the air compressor. So far the regulator is working great. It holds

This regulator bowl blew off the first time I pressurised it. I had Teflon tape on the threads when it blew. I took off the Teflon tape and pressurised again. This time my 30 gallon tank could only get to 75 pounds instead of the 125 cutoff. The bowl threads was leaking air at a high volume. The third time I took the bowl off, I studied

I purchased this for use on a Makita mac5200. It fits and performs well. There are arrows on the body similar to the original regulator which indicate air flow direction, be sure you make note of those when installing. When I first installed the regulator as shipped, the tank pressure read the same as the regulator pressure. As others

This is a generic valve and needs a slight plumbing change for use with a Makita Mac2400. The valve body is square, with a port on each face. Three ports are used and one is plugged. For the Mac2400 the plug needs to be moved to the opposite face. This is indicated by the airflow direction arrow on the valve. The rest of the plumbing

The product didn’t match right for my Makita MAC5200. One of the output hoses wasn’t in the right spot. As you can see in the pics. This is a big deal for a compact compressor. I had to shorten the hose myself to make it work. I would’ve sent the regulator back if I didn’t have a project that I needed the compressor right away.

Bought this to repair an older Dewalt/Emglo compressor. It fit fine and was easy to install, unfortunately I couldn't get the pressure relief valve to stop venting (it only stopped venting when the tank pressure and regulated pressure were equal, which is kind of useless). It was a slow leak, so it would have worked in a pinch, but I

As others have stated, the 1/4 NPT threads are overtapped so they will just barely seal--they did seal, though. It's weird that they managed to get the 1/8" NPT for the gauge right.

Some bits of flashing around the casting marks. I cleaned some off and then disassembled it to make sure the pieces weren't floating around

I thought I'd never have to buy another since it was I/R, ARO, at least a US company and QA even if made in Korea. Worked OK for a while (about a year) then started to leak at relief anytime tank pressure went below setting. Infrequent use. Sometimes you can get it to stop by raising/ lowering the pressure. Other times (now almost always)

Well thought out set of fittings and teflon to boot. Body is not plastic. Appears to be built to last. The knob is plastic and the need to pull it up to adjust the pressure is a bit of a pain.

I have had this for a few months now on a harbor fright airbrush compressor and it really made a big difference to my airbrushing.

I use this downstream of my onboard air to inflate tires to a chosen pressure without having to hold an inflator trigger the whole time, or risk over-inflating when attaching a hose directly between the compressor and tire. I've put a female coupling on the output, so to set it I plug in my inflator (with gauge) and dial in the pressure I

Bought this to improve air control on my airbrushes. Sometimes I need to use very low air pressures. The regulator on my compressor was impossible to adjust below 10psi with any repeatability. I bought the 3 to 30psi version and put it downstream from the air compressor regulator. I located it so it is at hand while I'm painting. It

I bought this to use with my pressure gauge calibration set-up for calibrating the gauges at a brewery. My old regulator "drifted" far too much, making it very hard to calibrate a gauge. This one works quite well and is stable once you get it to a desired pressure. Ports are the right sizes and locations for my use. This is a relieving

Sure enough right out of the box the threads were imperfect and had to be re-tapped just as several other reviews state. I got it anyway since this was ''Amazon's choice'' BUT I don't see how. In any case I am keeping it and will update if it starts leaking as others have also stated. I ordered 1/4" ball valves and put them on the

Overall it works fine. The threads on the outlet port were messed up out of box and I had to retap them.... Something you shouldn't have to do for a brand new product, but I guess you get what you pay for.
The inlet and pressure gauge threads were good.
The pressure gauge needle jumps around a little but is accurate.

Overall not a bad regulator for the price but it fail to meet my requirements. I did find the same problem reported by another customer with both of the threads.

Overall, this filter seems well designed, is easy to set up and use, and pulls out a lot of moisture. However, as other reviewers have said, if your application is very moisture sensitive, consider a secondary filter somewhere down the line or at your tool. Another tip is to install this filter a good distance away from the compressor

Nice little water trap, just be sure you have several feet of hose between your compressor and they filter. 25-30 ft is best. You have to give the air time to cool and thus the water vapor condense so it can be removed. I have this 90 ft from my compressor and after a 3 stage filter from the same company.

Total junk. At high flow this thing gets a harmonic howl that will drive you nuts.
