Great price. Great customer service

I bought one and installed it, only to find the dryer bowl leaked. I sent the seller a picture of the leaking part and two days later they sent me a brand new bowl. Impressed! Item works great.My only complaint would be there is no suggested setting for the lubrication system. Not having had one before, I’m not sure how much oil I should be picking up to auto-lube my tools. But I’ll figure it out by trial and error with time. Very happy with this purchase!

Pros
  • Really easy to install and it comes with I need.
Cons
  • Poor quality...water drainage valve broke just over a month in. No warranty. Cheap materials

Great value for my opinion

Using this to dry, regulate & oil the supply for a tire machine. I want to adjust clamping pressure when doing carbon & magnesium wheels to avoid damage and this works perfectly dropping from 130 to 50-75 as needed. I checked output the first several times with a trusted gage and all seems well. Verify your oil screw is set (so it actually uses oil) as mine was cranked all the way in presumably for shipping. Bowl seems sturdy unlike some other options I’ve tried in the past. Would purchase…

Pros
  • Good product works well
Cons
  • will not take moisture out of air.had to disconnect hose and drain water out of my air sander

Arrived fast. in my review

This regulator seems to be working as it should. I have not had a chance to really check if the pressure is accurate but it is filtering out water. I wish it had a better adjustment valve. All and all I like it for the money.

Pros
  • Bought 2 of them so far. I think they're great. Sturdy and priced reasonably.
Cons
  • The product requires a lot of maintenance, making it unsuitable for busy work environments

Leaks like a sieve: my feedback

This never seemed to get sealed up. Right from the start it leaked between the water separator and the luber. I disassembled it and made sure the o-ring wasn't compromised, lubed it with a bit of grease and reinstalled. I made sure everything was nice and tight. to no avail. Then, it started leaking from the automatic water drain. I'm done

Pros
  • Proven to be efficient in removing contaminants and providing clean air supply, making it perfect for use in a wide range of industries and applications
Cons
  • The product is not suitable for use with high-temperature air systems, as it can cause damage to the components

Good filter: my feedback

Shipping was disappointing, since it was delivered a day later than promised. But that was not the fault of vendor. I've used the filter only once so far, and worked as it should! We're happy campers!

Pros
  • I like the build for the price.
Cons
  • The product is not suitable for use with high-pressure air systems

good value for the money

Good unit for the money, would love for it to have an outlet between the filter and oilier as a dry air outlet. Good thing abut these units you can break them down and add an outlet.

Pros
  • Provides three essential units in just one product, resulting in space-saving and cost-efficient benefits
Cons
  • The plastic bowl tends to discolor and stain easily, making it hard to keep the unit looking clean and new

Valve on bottom of dryer leaks.

I just got my compressor wired and plumbed today and this regulater/ dryer failed on the first day. When I open the valve and allow it to pressurize, the valve on the bottom of the dryer bulb pops out and releases all the air.

Pros
  • Includes Semi-Auto Drain & Polycarbonate Bowl , 0-150 Gauge & Bracket，a pair of Air Coupler＆ Plug Kit, 2 x 1/4" NPT Fittings, 1 x Thread Seal Tape
Cons
  • The product is prone to freezing up in cold weather, reducing its effectiveness and reliability

It's all right if you can modify stuff.

Where you adjust the old drip has always leaked on me and there's like a plastic plug screw right beside the oil adjustment and I took it out cuz it leaked re-threaded it and put a brass quarter inch plug in it it still doesn't really deliver oil properly but the regulator works good and separating water from the hose.

Pros
  • The poly bowl is highly resistant to rust and corrosion, making it perfect for use in moist environments
Cons
  • The unit is very complicated and hard to understand, making it unsuitable for casual users

Revainrating 5 out of 5

Nice price for its features.

Threaded adaptors and fittings aren’t great that come with it but overall it’s a nice setup without hurting the wallet.

Pros
  • spray paint for small jobs around the house.
Cons
  • The water trap tends to rust quickly, reducing its lifespan and effectiveness

Broke after two years.

Purchased June 19 2020. It just burts yesterday. Just came back from week vacation. Glad it didn't break than. Don't see any parts listed to repair.

Pros
  • Offers reliable protection for your tools and equipment as it prolongs their lifespan by preventing corrosion and other damages
Cons
  • The semi-auto drain is prone to jamming or seizing up, requiring manual intervention to clear the blockage

Dead on delivery - my new review

Dead on arrival. You have been warned!The pressure regulator has a bad section from about 75-110 psi where the dump valve auto opens and drains the compressor tank. Normally the dump valve only opens if you dial down pressure on the output section. It should never dump supply side as this one does. Note it is labeled in and out so zero chance I have it reversed!I ordered this over a year ago never installed it till today. Just cracked the box and installed it so I’m out of any warranty.

Pros
  • Good price, good quality, feels a little cheap, but it is... it works ok
Cons
  • The product is not durable enough to withstand rough handling or misuse

Solid air filter. on my review.

Excellent unit. My air is now completely dry and clean. This is my only source of filtration. Just be sure to wrap the teflon tape properly, you don't want any pieces coming off in your air line/tools. I leave the first 1-2 threads untaped to make sure of this. The teflon tape provided is a bit wide which is why I offer this tip.

Pros
  • Works great, This was replacement for old regulator that had leaks.
Cons
  • The product is quite heavy, making it difficult to install and set up

Revainrating 5 out of 5

great price for my opinion

not got to really got to use it yet only checking for leaks and so far it seams fine easy to use and well made Operating Pressure: 0-125 PSI.

Pros
  • Operating Pressure: 0-125 PSI
Cons
  • The bracket is prone to bending or breaking, making it difficult to keep the unit securely mounted

Worth the money for my home garage.

I have a 20 gallon air compressor for my garage at home and don't use it a ton but this water seperator/ oiler works great. Had to tighten everything down pretty good. I did have a small leak after install but works great after I put a little muscle into the clamp section.

Pros
  • Comes with a semi-auto drain, making it easy to remove moisture and debris that accumulate inside
Cons
  • The product is prone to rusting and corrosion, reducing its lifespan and effectiveness
