California Air Tools CAT-1P1060SP Ultra Quiet Portable Air Compressor - 1 Gallon Steel Tank, Oil-Free, 56 dBA, Lightweight (0.6 HP) - Perfect for Home DIY, Garage, Workshop, and Indoor Air Tools

Boy this thing is quiet. True, you are not going to forget it is there, but the average polite conversation isnt going to be disrupted by it either even it is sitting at your feet. FWIW, I use this at an SMD rework station for blow-off, drying, and powering small air tools where it has replaced my little DeWalt pancake unit. When the DeWalt kicked-on, I’d always flinch and often turn my head away from the noise. No more! This fact alone made this a worthwhile purchase for me.This compressor has a very pleasing “putt-putt-putt” sound, unlike the obnoxious “braaaaaap!!!” of other units, yet the air output is impressive for such a small unit. As other reviewers have mentioned, it only takes 60 seconds to fill from empty, and 15 seconds to refill itself to the cutoff pressure (~120 psi). Although my use case is pretty specific, I can definitely see where this unit would be a good fit for air brushing or powering a trim/brad nailer. And of course it will handle the usual tasks like inflating bike tires, car tires, athletic equipment, and levitating random sleeping cats (KIDDING!).Perhaps the biggest “like” (other than being so quiet) is the portability factor. Im guessing it is about 35-ish lbs which means even an over-the-hill duffer like me can pick it up and take it to where it is needed without needing medical attention afterwards. Its actually pretty well balanced. Hefting it up to the tailgate of my truck did not evoke any colorful language from my back. :) All in all this is a very impressive little compressor without any visible downsides. It is well-built, runs cool and is basically a steal at this price. If you need quiet, portable air in small quantities, you will love this thing. 5 stars.Update: July 19, 2020: When I went to throw the box away, something in the bottom rattled. Hmmm... Curious! Further investigation revealed an intake muffler. Wait... what? So I installed it. This means that when I wrote the review above, it DIDNT HAVE THE INTAKE SILENCER ON! After installing the silencer, its even quieter. You can listen to music or talk on the phone while this thing is running. Unreal!I use this compressor every day and it really deserves six stars. It sits beside my rework bench and just purrs along. Love it!
