Review: Great Compressor So Far - This replaced an old 2HP compressor in my shop. This builds pressure super quick, is super quiet and is working flawlessly so far. I have it hooked up to an IR Air Dryer and I run both drain valves into pneumatic sintered silencers and into a gallon jug to catch the bleed off since I don't want to route it outside for my neighbors to hear. It's a quiet setup and works wonderful for my milling machines and blast cabinet!
Review: Super quiet compressor for a personal workshop - The noise level is something else. This replaced a large standard style compressor that I wore hearing protection for when working in the shop if it was running. Now you can have a normal conversation. Tank is small but the system is basically designed to run on demand, I've never run out of air operating my vapor blaster or anything else. BUT it's like the outsourced the painting of the tank to children. I've only had this for a year, it lives in a heated & cooled garage and the paint is just flaking off every weld on the tank and getting rust. I'm going to have to remove the motors, strip it and repaint it to avoid it turning into a pile of rust.

### ⭐⭐⭐⭐⭐ Best air compressor out there, quiet is key for the garage shop!
*by B***N on January 6, 2026*

This is definitely the best compressor I've had yet. It's much quieter than the dual piston one I had before. Its capacity is pretty close to the one I had, perhaps just a bit more. I added some wheels to it so I could move it around. It's not that I move it around that much being it's 220V, It's that I have it under my bench and need to move it around when I want to work on the dust collector system.
