Quiet Down your AIR COMPRESSOR with air silencers and a Magnaflow Muffler | AnthonyJ350

The most cost effective way to kill the sound without worrying about thermals is to move the drive motor-head assembly off the tank. I did this by welding up a cradle for the assembly and a wall hanger, hung the cradle with isolation hangers and routed the output through a 3/4 copper condenser then down to the tank. All the high end noise is gone, there's no notable vibrations, and I don't have to worry about heat buildup because it's open air. This is with a Campbell Hausfeld TQ3010. I've been very pleased with the results and it looks amazing to boot if you like that old industrial aesthetic. I haven't touched the intake side yet but the idea is to change the two small canister style housings for a washable K&N car type. I'm just not sure if I want to fab something myself or by a molded plastic housing and tie in. Though, that's more for easy maintenance than anything else at this point.

Some compressors just make a ton of noise. I got a tour of a diesel body shop and they had a cool compressor setup. Their compressor was an old Ingersoll unit with a big piston. It made a steady thump-thump-thump-thump sound that was a lot like a 4-stroke dirt bike but slower. The 200 gallon tank was wrapped with tires and ratchet straps. Naturally, it being a diesel shop, they had a big chrome stack welded to it and a fan from a semi for cooling. That was quite possibly the coolest shop I've ever been to. It had this derelict look to it. Galvanized steel buildings. One had a really high ceiling with a bunch of engines and 55 gallon drums. The other side was the workshop. 4 bays. Disassembly, cleaning, fabrication, sandblast/paint booth.

I’ve had that same compressor and motor for about 6 years now and it runs like a champ. It’s the only air compressor that’s never needed draining either. I check the drain valve once a year and there’s never any water inside but she’s noisy haha the reason I’m here. It’s probably the loudest compressor I’ve ever owned too.

I am coming in way late but A natural loop of the rubber tubing will get rid of a lot of the high freq noise. Also at the bottom of the muffler you can add a common 4cyl airbox with flat filter. Pretty much any airbox from any car will do but the 90's Toyota, Prius are super common and they have a clip style box that you can change without tools. The filters are the flat rectangle style and they are cheap, (Probably way cheaper than the K&N and have way more airflow) I know Toyota mount to a flat surface so an easy wall mount can be done. You can do this backwards and find out what is a common car cheap K&N filter and find out what car it goes to. My Uncle had one of those huge Tornado dual snorkel 455 air filters for his Compressor. He would just unscrew the wingnut and blow the filter out every so often. The Air box style does have internal dampers to help with noise.

Build a small cabinet or enclosure that's very simple. Just 2x4s, MDF on the inside, 1/2" plywood on the outside, and use rubber washers to standoff the MDF boards from the 2x4s and the screws attaching them. When you fit it all together, caulk the seams with something like Big Stretch caulking. If you want to go a step further, fill the dead space with batting. Further? Put anechoic foam wedge tiles on the MDF facing inward. Even FURTHER? Put a sheet of mass loaded vinyl over the MDF on the inside and put the foam tiles on top of that. For cooling and air intake, build a port on the side facing away from the shop and make it a baffle stack which forces the sound to hit several 90° turns. Put a fan in one of those baffle ports at the bottom and put another port on the top. Hot air will rise up and out. Line the walls of the baffle ports with anechoic wedge foam tiles too, but you can just make them out of the plywood. If you go all the way to the mass loaded vinyl and tiles level of design, that thing should not be any louder externally than a quiet conversation from a few feet away.

You're on the right track! Next step would be an enclosure. Castair has an option if your interested try them out.

Use rubber mounts for the pump and maybe the motor onto the bracket. Mine [tank on its side] has large rubber feet. Which deadens the sound a lot. And yes that is the way it was made!! That big upright tank loved in America drums big time. That hose restricts the air intake big time.

Great video and answered my question on how to quite mine down. After listening to mine today cycle on and off I said there’s got to be something. Nice build

I have the same compressor. I messed with a muffling it when I got it because it's so damn loud. I have it in a compressor room, that helps the most.

Nice setup. I did something similar with a moped boxed plastic intake and routed it through wall so intake was outside

Nice Rinnai unit you have there 🎉

Where did you get the part used to attach the silencer to the compressor?

Wonder what dynamat on the tank would do?

What was the app that let you see the sound frequencies?

instead of a muffler, get a $30 "muffler" for a central vac system. works much better and much less restrictive than what you've done.

Medical compressors are worth the investment, they are powerful enough for simple DIY stuff.

Either way you do it a compressor noise is still annoying as hell.

Sell that loud big box store turd and get something from the Quincy QR-25 lineup. Buy once, cry once.

All that for 7 db...sorry, that's a fail...

Wow, step away from the compressor, and walk away. You clearly have no idea how compressor intakes work
