Air compressor : REALLY effective sound reduction modification.

[rdill]

I appreciate the ingenuity. I like modifying things out of other parts. Who gives a damn how you use a Crescent wrench. Who cares about adding another 100 ft of hose and putting it in the next door neighbor's yard. Too many damn haters. Creativity and just making stuff is fun. Keep it up sir!

"Ideas are worthless until you get them out of your head to see what they can do..." Great idea and well done.

If you flip the lid on that filter box it sounds really cool when the secondaries kick in

I reduced my air compressor's sound by 10db by putting a screw-on air intake muffler (bought it from MCMaster) that is the same principle as what you did; however, I realized a huge amount of noise comes from the tank amplifying the vibrations produced by the reed valves and whatever else is knocking about. So I put some rubber vibration reducing sheets on it. Putting some rubber matting around the tank helped but if you can figure out a way to apply some pressure on the tank itself with a clamp of some sort to stop the vibrations you can significantly reduce the sound. To see what the effect may be, squeeze the center of the tank with your hands. Doing this to mine significantly decreases the noise but I haven't messed with it further.

Michaelovitch: Very clever approach to a solution. I cannot completely understand how the air intake/filter adds to the overall noise, but your idea not only reduces the noise, but changing filters will be easier. The automotive filters may even work better than the factory filter elements. Again, well done.

i dont get the dislikes... this is a brilliant idea, not everybody (like me) has a choice on where the thing stands (in my case, my shop is small and i need it there) i'mma try to construct an air filter housing myself since your proof of concept worked great. i mean... its not only less noisy, but i bet you that a car airfilter can pass through an aweful lot more air, hence the compressor can work more efficiently. i mean yeh... you just spent like 15$ max. for the parts and the damn thing is only half as loud as before, so thumbs up.

I effectively reduce the sound of my compressor by adding another 50' of hose and rolling it away from me....

Nice video. However, I would of put the inlet facing down so it didn't collect water or other junk. Put a screen over the inlet to keep bugs from making a home. And, I would of put the hose nipple on top facing towards the compressor and ran one hose with a T fitting. Those cylinders aren't pulling that much air that they need independent hoses.
But I like the idea and the video build process. Very clean, no crazy music, straight to the point. Nicely done! :)

Brilliant :-D, that made a hell of a difference, all the low frequency chugging has vanished, you clever cloggs :-D.
If you needed it better than that, a box to cover the unit with soft padding glued inside to absorb the high frequency content.

They look like plumbing/outside tap fittings, absolutely ideal :-D.
I love creative modifications.

Resonance of the steel tank is a very big factor. A few cans of rubberized undercoating sprayed on the tank would help a lot.

This is something I have done for years. Here is a simple thing I can add that I have found to make it quieter. The tubing comes in a roll. Keeping everything else the same leave (add) about one natural loop in the tubing. The circle gives the sound more area to bounce around and the change in direction also helps to absorb more of the higher and lower frequency noise. This can be quickly heard by measuring the sound at the end of the tube straight and looped. The flexibility of the hose is what helps absorb the sound. Also the filter box itself has sound baffles in it so setting the intake(s) to flow in the same direction, as shown, also help deaden the sound. This simple mod can also be used by body shops where there is a lot of dust and in case of bad placement of the tank you can make the hoses longer and remote mount the filter. In the case of a car mod shop you can now re purpose that Corvette (insert car here) air box you just swapped for the K&N set up. Also don't forget motorcycle filters.

nice job, that reduction in noise can make a huge difference when you in an enclosed space like a garage or even just working close to the compressor, 2 thumbs up for this video.

[Damianium]

Must have added at least 25hp at the wheels with that cold air intake!

[scottfirman]

Much better filter system anyways. Looks like you took it from my old Yugo, lol. Nothing wrong against doing a modification as long as it can breath, and it can, so who cares. I built a small insulated box in the corner of my workshop and added a light inside as a heat source because my shop was not heated until I actually used it. In the winter it would be so cold, the compressor motor would blow the breaker because the oil was so thick the motor wouldnt start. I found by adding an insulated box for the compressor and putting the light on a timer, it would go on at about 5am . By 9am the compressor would be warm enough to run fine. My dad used to put a work light under the hood of our old cars with a wool blanket all night so the carburetor wouldnt ice up and it would warm the under hood of the car enough to help the starter and oil. Eventually he ended up installing engine heaters on all our cars, it would keep the antifreeze warm and the car would start easily every time. Granted this was back in the early 70's. We live in Michigan and it would get extremely cold back then. -35 degrees in the winter. We dont get winters like that any more and I dont miss them eather.

[johnnewson]

the best modification i have seen on a compressor so far. going to try something like it myself.

[pat]

Out of all the sound suppression ideas I've seen on Youtube, this is the most effective. Good idea!

[sugavmig]

i like this. neat that you can also filter the air and the compressor / tools will run cleaner and have a longer lifespan.
great idea.
the people hating is just those "know-it-all-do-nothing" types. keyboard warriors.

keep it up

[yhardtop]

Thanks for the nosebleed. By the way, breathing through those long hoses will significantly reduce the CFM output of the compressor.

[billybl]

Thats a good idea! I just broke off one of my plastic air cleaners so this will come in handy. I also like the idea that if you use the right airbox, when it's time to replace the filter you can just walk into any walmart and buy it off the shelf.. hmmm, I think I'l use the same air box that my truck has. Thanks bro!

Just a tip as im not sure if you know this. The locking nuts us used hve to be completely threaded on for them to lock. Now if the vibrations aren't to bad and you have 3/4's of them threaded it should be fine.
