Durable Aluminum Material
With the cast-iron cylinders and a heavy aluminum body, this 3hp air compressor pump has strong thermal conductivity and is suitable for the dusty field environment.
Double Cast Iron Cylinders
The conjoined twin-cylinder, with small vibration, low sound, and strong heat dissipation function, runs vertically. Its simple structure is easy to maintain.
Belt Pulley Design
The strength and wear resistance of materials are improved through heat treatment. Coupled with the belt pulley drive design, our air compressor pump has excellent compression function and can operate stably.
Excellent Components
Our 2 stage air compressor pump comprises tapered roller bearing, needle roller bearing piston ring, control elements with the extremely high bearing capacity, and the aluminum head and valve plate for heat dissipation.
Oil Viewing Window
This air compressor is designed with an oil viewing window and an oil drain plug. You can monitor the machine's oil quantity in real-time. It is convenient and intuitive to observe.
Versatile Use
Our air compressor is capable of replacing defective equipment or extending the existing compressed air system. It is widely used in chemical, electronic, textile, food processing, and other compressed air industries.

Like many Amazon reviews you must assess the reviewers understanding of product to determine if it is a fair assessment.Seems most of the negative reviews for this pump are likely from a lack of understanding how to properly install & setup.Granted the manufacturer/ distributor isn't doing themselves any favors by not including instructions on the issues which should be checked out prior to pump installation - even if they don't provide detailed instructions.The reviews of failed units are more likely attributed to failure to check the following prior to installation.1. PROPERLY match motor to pump. By true amp draw & not just stated HP SPL.2. Test your presure switch & unloader.Make sure you T off for the unloader line.3. Remove & clean check valve.4. Don't just use your old pulley & expect magically its going to run at the proper RPM - actually DO the RPM calculation & get the CORRECT pulley size.5. Check for burrs & manufacturing /machine defects & repair PRIOR to installation. YES - This is on you as the installer -6. Properly align motor & pump pulley.That's most of the items & if you don't understand any than either research or bring it to a qualified service professional.Ignorance & failure to properly diagnose, engineer & install the pump shouldn't be a reflection on the product. Take responsibility for your workmanship.

Downside is no directions as to type of oil, how much, bolt pattern, break-in and things like that. I was worried about the packaging as a lot of them arrive damaged and I can see why. Mine came wrapped in some white foam, but I was lucky it was not damaged. A few of those air bags would have made the packaging much better. It took forever to put the oil in it (it takes a quart). Pour it in through the orange relief valve SLOWLY. I used some synthetic compressor oil that runs about 10 bucks on amazon. I ran it for a half hour with the valve open to break it in like my DeWalt said to do on my other compressor. This pump replaced a pump on a Husky 60 gallon tank. Mounting was not a straight bolt-on, but if you are using a compressor, you should have no issues with this. I had to redrill the mounting holes for the pump and the motor. Rerouting the line from the pump to the tank just required a couple of compression fittings and some 1/2" copper tube and pipe bushings I had laying around. I like the cooling fins on the discharge air to the tank. All pumps should have that. The flywheel was aluminum and very light. I consider this a plus as it cools the pump as it spins and reduces start up torque. The pump did not get as warm as I expected. I had a 3.5 " pulley on the motor so with the 10.5" pump pulley, it took a little bit longer to press up, but not bad. Quieter than my Dewalt, but it's not working as hard either. I plan to hook the two compressors together for a large reserve of 120 gallons and lots of airflow. The pump says it will press to 115 psi, but that is really dependent on the set pressure on the control. Mine runs to 125-135 psi before the pump shuts off. Time will tell if the unit holds up, but initially it seems like a good buy. I would like to know how the one reviewer actually contacted this Happybuy place (and got GREAT results) as I could not find any contact information at all.

update, failed within 2 moths, and cant get any help from any warranty.read a lot of the review, and the sellers description is very vague, doe it come with a 12 inch pulley or a ten inch? mine came with ten inch, which made me go purchase a new pulley for motor to get proper speed. oh well. the pulley is VERY light weight aluminum alloy of sorts. doubt it'll hold up too long. the specs the seller advertises as cfm output of this item are WAY lower actual output. quite disappointed in this, but I've already invested in this piece of cr.. so I guess I'm stuck with it. the oil drain is on the bottom of the very thin flimsy aluminum lower casting and you cant get to it with the unit mounted. glad i bought the extra warranty, they wont replace t, just refund what i paid, seems the seller ahs changed the description of the part several times on its specs, so what was advertised, they change later and say, no its just like we advertised. shipping was a joke, ordered on Sunday, they didn't ship til Thursday. delayed its advertised arrival time by several days. i wont buy another one of these, big waste of money, but the quality part and save time and money in long run. We'll. It scrapped out, won't build over 35 psi at this point

When we received this product it was sticking out of the box and the cover to the filter was broke. My husband glued the box back together. So far it's ok.

Arrived in good shape. Added oil, turned upside down to mix internally. Hand turned flywheel to free it up. Runs pretty quiet. However it did not run over ten months, then quit!
