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.

"Those cylinders aren't pulling that much air that they need independent hoses" When you let the hand in front of the airbox intake ,while the diameter is huge ,you can feel two distinct pulses,wich mean the quantity of air is far from ridiculous. As soon as you have several cylinders,if you can use one intake per cylinder ,do it,the benefit is real. There is less charge loss for each one of them. With a T or Y you would suck the air being in the piping of the other cylinder too,wich reduce the fill up efficiency of each for the stroke after ,since they suck each other's residual air in the piping. I agree for the other mods,they are good ideas. i didn't do it because i use a tarp on the machine when i don't use it. Thank you for your words : )

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.
@michaelovitch

What you are describing is looking pretty good to me. The air filter is square,i 've installed it so the paper fins are perpendicular to the air flow,for killing a bit more the sound waves. I wanted to use rubber hoses too ,to reduce the sound level a bit ,since they are thicker and denser than this plastic tubing,but i only had those in hand. I think i will try what you said. thank you.
@srussert28
6 жыл бұрын
You actually want some flexibility in the hose. Think of it like hitting a cymbal. The more ridged the tube the louder it will be. Fish tank tube is probably the least expensive and comes in various wall thickness. If it can handle pulling a column of water from a few feet it will be several hundred times what is needed to not collapse under air vacuum. Heater hose works but is generally more expensive because of the environment it is required to work in. Most water hose will work but is more ridged but a few more loops will usually do the trick and who doesn't have a damaged water hose laying around. DANGER ! DO NOT try using a water hose until you blow the water out or the nest of wherever built a home in there over the winter! Another tip, mark the number of the filter on the air box itself. This makes finding and double checking the size of a new filter much quicker. If you are doing this backwards you can find the largest filter at the parts store and then find the year and model car for the air box at the local salvage yard. Don't forget Motorcycle and Big Rig/Tractor filters for shops that do that kind of work. Think of it like this if your motor is 20 HP then practically any internal combustion motor will flow more air than that. On a different note Dyson vacuums are being thrown away more and more and I wonder how well the dirt catcher part that has the simple one finger dirt release would work as a dirt catcher Before the filter? You may have to double or triple up to get the proper airflow requirements but then you might have an extremely low amount of dirt that even got to the filter. Dyson is focusing on battery power so expect to see more of the older ones being dumped.

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.

Hey Michael, Thank you so much for your help and your emails. I went to a few hardware stores and ever online store you could imagine. I even took a snap shot of your coupler and no one understood. Anyway through trial and error back and forth on Amazon I finally got the correct fitting here it is for my application. 1" Hose ID 1/2" Male NPT MNPT Straight Brass Fitting which did the trick. This is even better because it’s one piece brass. Amazons sizing was matching my inlet size that’s where the back and forth came in. The exhaust hose was another story. Question how hot does your hose get when it’s running? Did you use a certain type exhaust hose such as reinforced and high heat should I be concerned about the type hose because I don’t want it melting or failure during a job. Regards S.I. John

Hi, I only modified the inlet part. The airbox feeds the compressor through the rubber hoses and the fittings you got. The pressurized side is the stock one,and there is no point modifying it for noise reduction,air being compressed and set directly to the tank,wich is not letting noise go out. The hoses i use are just automotive coolant hoses,wich are softer and conduct less well sound than the ones in the video wich are semi rigid garden hoses. The heat will not be as high as on a car engine ,so it should be more than ok. You don't have pressure side hoses on your set up ? Are you talking about the hose feeding the tools ?

Nice proper use of a car's air cleaner box. I did a mod on mine where I used a cotton gauze car valve cover vent filter for the intake filter as the stock one on the compressor seemed very restricted and was hoping to decrease tank fill-up time. 1/2" 90, with open cone filter. Looked like a mini car ram air intake. Sounds the same, maybe a tad louder, and to my disappointment, even though there is now way more surface area going into the compressor, it took about the same time to fill up tank from completely empty, maybe a second quicker, if that. 33 vs 34 seconds. Also, changing the motor pulley to a bigger one will make it pump faster, but you will loose torque, and less top pressure, if that matters to you. Or maybe not as the pressure switch may shut-off before max torque on the motor is used.
@michaelovitch

Thanks : ) The pump rotate faster,yes. the motor is strong enough to start under load without problems. the top pressure is the same,the pressure switch switches on and off the motor at the same exact same pressure than before,i didn't touched it. the only problem could be the motor asking more amps to keep going at the same speed while working a bit more harder. I just need to measure the amperage consumption,and if it's within what's indicated on the identification tag,no problemo : )

Your right now that I thought about it this motor doesn’t produce nowhere near the heat a car engine does. Sounds like you have a lot of experience in the field. I have to admit loud sound like what comes from these engines and leaf blowers not just bothers me but makes me angry it sets something off in me and that’s why it’s important for me to address this issue on my 30 gallon air compressor. I’m also hard of hearing in the high pitch area go figure.

At 12:25 those hoses are the intake hoses. Air is sucked in through them. They don't get hot. Noise is not really good,it's a good thing you try to reduce it,it's a big source of stress.

Very clever idea.. I would be concerned of the hoses causing too much restriction though, stressing the compressor and sacrificing some performance.. what do you think?
@michaelovitch

Thanks. The brass connectors have the same or superior surface area to let goes in,so it's not a restriction. the hoses length could be a concern for air charge loss,but it's not practically,the fill up time is the same than with stock filters. It's not like if there was 5 meters of hose,and even there,the air pulses are fairly low speed and low frequencies,so a long tube is not that much of a restriction i think.

It is not that the subject matter is boring. There is an optimum length for an adult's attention span that you have exceeded. The best content DIY providers spend a lot more time editing their videos than they do shooting them. Jay Bates (and others) has discussed this numerous times on his channel and associated offerings. Less is often actually "more". There is power in being concise.

Look. I am trying to be constructive, not a jerk. As but one example: In the very beginning of the video, you took almost one full minute to repeatedly show us how you could reduce the decibel level by covering both filter intakes with your fingers. You first did this five times with the intake pipes pointed down and another five or six times with the air filters rotated a80 degrees. Covering those intake holes up once or twice would have been adequate and taken only about five seconds to convince us of the noise reduction. This one example would reduce the length of your video by almost a full minute. In general, you simply repeat your actions far too many times. Trust me . . . we get it! If there is something unclear, I can always back up the video and repeat it. Your video is not per say, "bad", but it would be a lot more enjoyable with some editing improvements.

Thank you,i understand. Maybe i should have explained that pointing air inlets towards different directions have a purpose in the video : Sound is waves, and following how you direct the sound waves you have different results. Upwards,you reduce the rebound on the ground,one pointing the other ,you could think they cancel each other. This is exactly what happening in the airbox,with the paper filter,they just rebound on the paper elements until they loose energy.

nice mod ! i did similar but on a fixed compressor. twinned the inlets and routed the inlet pipe to the sheds outside wall and put the inlet outside. makes the workshop a lot quieter, annoys the neighbors more, and compressor gets cooler air. you may find fitting a smaller inlet on the car filter will reduce noise a little bit more. otherwise its a very good mod.
@michaelovitch

Thanks : ) It's what i thought about the inlet size,i can hear a deep low tone pulse from there. I would use a baffle on the actual section to avoid sound to exit through the intake. I still think about it. i will work on the relief valve too,it's really loud and make a huge sound spike. You did good on yours,i hope you kept a filtration system though. The cooler air is very good idea.
@tweake885
6 жыл бұрын
for mine i used the stock filters. a car filter intake like you have done is better as it has more volume to dampen the pulses and the filter is so big it may never need cleaning. but even with stock filters there is still a gain due to them being joined. ie one cylinder sucks through both filters giving half the losses. piping the relief valve would be a good mod to do.

Just a couple of observations. 1. I assume with less restrictions and an obviously larger opening, the tank filled faster? Or the same speed the motor was just less strained I'm sure. 2. I think based on the way the filter sits, you are pulling air from the top of the unit, out of it's seal. I think it should pull from the bottom so the filter seals in the housing.
@michaelovitch

1. Just better air filtration,the opening were enough looks like,fill up time is about the same. 2.The air is pulled from the bottom of the airbox,go through the air filter,and then through the two hoses. The upper part of the airbox is sealed from the lower part by the filter,wich divide it in two separate volumes.

the solution is very effective to reduce the intake noise, the next step is to reduce mechanical noise but this step is much more tedious as you attack the design itself of the pump on details as the bearing clearances , the piston clearances on their bores, the design of the reed valves etc, etc . I done the same thing on my IR 242 compressor, I used a VW beetle air cleaner and I made the plumbing with wrough iron piping as this compressor is 2 stage, V-2 configuration

I just used heavy duty silicone bushings from a vehicle to mount my compressor and built a cabinet outside my shop for it. All controls, regulator, drain valve, and manifold are hard-line into my shop. I flip a switch and it turns on/off. I know its running, but it disappears into the background.
@michaelovitch

It's the best to do if you keep it on a dedicated spot. I have to move mine around a bit,so i can't do that. Silicone bushings is a good idea. Spraying the tank with bedliner or something similar helps to reduce resonance too,like separating the tank from the pump/motor assembly.

Does having the air intakes for each cylinder fed from the same filter box affect them (other than the noise level)?
@michaelovitch
6 жыл бұрын
It does nothing. The same happen in your car. As long as the filter is big enough to let flow air through it,you can feed as much cylinders as you want. At worst you will have air pulses to create air turbulences in the airbox.

I wonder if you lined the box with foam if it would help dampen the sound. Maybe put a box fan ontop to cool it or something with foam and fans. My damn compressor is loud as hell. And a simple hose from the exaust tube works but it still is loud. J thought of building a cabinet, but heating issues etc. I dont use it often enough as it is. So closing the garage door and letting it fill up works. Its a larger tank. If you could somehow put a the engine in a freezer and the exhaust in a sound proof box.. bam. Just doesnt sound cheap or easy.
@michaelovitch
6 жыл бұрын
Yes,dampening the airbox with sound insulation foam would work for sure. The sound is passing through the filter,wich reduce it quite a bit,and then bounces in the bottom of airbox before to exit. Sometimes have specially designed airboxes,or piping with sound dampeners ,like pockets zones ,or baffles. Cabinets can be a good thing if you don't plan on moving the machine often,and don't need to be fully closed,so you can cool it down. You just need to kill the sound waves by letting them bounce on specific angles. Just look how anti noise walls along freeways are made,like their angles. The point is to direct the waves and keep them in the cabinet,or box. That's what my system does witht the air fliter,even if it's a basic system.

Love it! That made a big difference! These are the things I enjoy doing with my own stuff as well. How much reduction in dB did this make? One thing I realized right at the end was that the filter is being used in reverse flow. Meaning the typical way air is being sucked through the air box is from the top side hole through the filter and out the bottom side. Perhaps in this application with such a lower about of air intake the filter will stay in place where as with a vehicle the filter would be lifted out of the air box's filter lip. Anyway, loved this video! Thanks!
@michaelovitch

Thanks : ) A bit more than 4dB wich is very good i think : kzitem.info/news/bejne/o39pnGqng3yDqaw The filter is used in standard flow direction,not reversed : the air is sucked on the lower part of the airbox ,pass through the filter and go from the top part of the box towards the engine. the taller media (paper) fins are always on the dirty side of the filter ,to allow more surface to catch crap and stock it. You can have same length fins on each side too,the filters last less by idea,but flow a bit more,since less surface the air have to travel through. (this parameter change with the state of dirtiness of course)
