CAT-60040CAD 4.0 HP Ultra Quiet and Oil-Free Air Compressor, 60 Gallon Steel Tank, 75 dBA Noise Level

First thing, it arrived 2 days early. Although it is too soon to see how well it lasts I am totally amazed with the quality and workmanship in this compressor. The welds are perfect, the motors all are tight, there were no air leaks from the moment I fired it up. Stainless steel braided lines, complete with regulator and auto water drain. All I had to do was screw on the air filters and plug it in. When they opened up the truck I was shocked to see the compressor laying down! You cannot lay down an oil based compressor but this is OILLESS. the driver explained that with the oilless ones there company would rather lay it down properly rather than have it fall over. Again, someone taking an extra step and having pride in what they are doing. . And it really is quiet. Quieter that my little pancake style compressor. As I said, it is too early to tell how long it will last but my first impression is that it will last a long time for what I have in mind with it. Would definitely recommend 100% and would definitely buy again. Great product. And customer service was right on top of things when I sent a few emails with questions. They got back to me in about an hour or two. Happy customer, very happy.

Owned this unit since November 2019 and it gets used at least 2-3 days a week every week since new roughly 6 years ago. I have air lines run throughout my shop and hose reel outside in the driveway. I use it for filling tires on vehicles I work on or my yard equipment, for blowing things off as cleaning or myself after mowing/edging, sometimes use air tools like a cutoff wheel or die grinder, drying off my dirt bike after washing, etc etc. It's pretty quiet compared to other compressors for sure but it's not "quiet" per se. You can still somewhat have a conversation near it while running. There are some small leaks on mine that I have tried to block off completely but every 24-36 hours I will hear the motor kick back on from a slow leak. It is set to turn back on at 90psi I usually just leave it full at 120psi so it's always ready to go whenever I need it.

I had a Craftsman oilless for 29 years that threw a rod. That thing was so loud I had to wear ear protection. I was skeptical about the noise level this was advertised at. I need a decent sized compressor for my shop and looking around at more conventional compressors in this price range. What it came down to was getting a compressor this size to my garage. These things are all top heavy and I didn't want to have to go to a dock and have to have it loaded onto my truck then figure how to get it off the truck and into my shop. Amazon saved the day, free shipping to the house for the exact same price I would have paid straight from California Air! Two guys in a box truck and lift gate brought it here and put it into the shop. This thing has the auto drain on a timer, dual compressors on the top. They can run at a lower RPM than the old style thus keeping the noise down. Another great fact is the power required to run it. A 20Amp double pole breaker does the trick. Many compressors this size require a larger motor to turn the multiple stage compressors, upwards of 40-50 amps on some. Check the power requirements before you purchase! The noise levels in the pictures, 79dB is 1 foot from the top of the copmpressor and the 72dB from 12 feet away. The last is how it is shipped, on a full size pallet with a cardboard box over it. Plenty of room to keep a dock worker from spearing the tank with a truck fork. Arrived safe and sound.

Quiet. Seems to work really well. Low amp draw should make it cheaper to use. Packaged well and put where I needed it. The guys were great. Not trained very well. But great attitude. Could have given a heads up. But worked out.

DO NOT BUY!! My shop is suffering for a defective conpressor At this price of almost $5k , it is totally useless I reported the problem withing 2 hours of receiving Completely inspected the unit before install, had to modify my power system to accommodate the specific power cable plug , it does not support the rated air flow suggested by manufacturer, and its banged up Shipping containment was perfect, all defects were from manufacturer Now im stuck with it or I have to pack it up and send it out and wait 5 weeks for replacement We can not run our auto shop with out a compressor! 😠

Ive had this compressor for nearly 2 years. It is quiet compared to the regular oil filled compressors, but it has a hard time keeping up with a blast machine. I use my blast cabinet at 60psi and this compressor is on constant to try to keep up and it even starts to loose pressure after about 5 minutes. I have used mine for many hours. One of the valves blew which are relatively easy to replace, California Air Tools charge about $40 each, they are like a thin feeler gauge steel about 1 1/2" by 1/2". I found them on AliExpress for $7 for 4 shipped. Overall, quite a good compressor that is reasonably quite and would work well for occasional use with regular tools but a little under performed for a blast cabinet.

Running extremely quiet

Very loud. It starts off really pleasant, but gets louder and louder as the tank fills. I have to wear ear pro to tolerate in the garage.
