Otherwise, the air compressor will burn up and might catch fire or explode. Make sure the construction has proper ventilation and ample room to comfortably accommodate your air compressor. You just have to find the one that best fits your unit’s dimensions.Ī budgeted way is to make one from scratch right at home using concrete blocks, cardboard, plywood or some fire-resistant material. Soundproof boxes for air compressors are available in the market. Literally locking up the air compressor in a spare room away from your worksite or in a soundproof box will definitely quieten it down. Imprison the Air Compressor in a Soundproof Box.Budget-conscious customers prefer this technique as it is inexpensive as well as easily available online. This approach will sever the unit’s contact with the surrounding surfaces, and you will notice a significant reduction in the voice level of your compressor. You can either use an old carpet or a sound-dampening material to wrap around the compressor’s entire body. This is the simplest method for silencing your air compressor. Else, the blockage will force the unit to run harder and louder. Also, regularly clean its air filters to prevent the accumulation of dust in the air intake passage. Proper and quality lubrication will both effectively muffle the noise and extend the unit’s life. You need to lubricate the bearings and metal components of the unit to minimize friction. If you don’t contain the friction, not only the noise will grow higher, the metal parts of the air compressor will also start decaying. The same is the case with air compressors. These bearings move in different directions when the machine starts running, which causes friction. Machines with movable parts employ bearings. Consider doing that when placing the air compressor in a corner or small room. Similarly, you can also install paddings on the walls surrounding the air compressor to prevent echo. Also, place a rubber mat between the air compressor and the surface it is placed on to prevent the unit’s body from constantly hitting the hard floor, eliminating the impact sound. You can apply rubber grommets on the motor to mute its vibration when running. The use of rubber for your air compressor will prevent the sound of vibration, shock and impact from spreading and therefore dampen the overall noise of the compressor. Rubber is famous for its sound absorption quality. By doing so, the compressor will draw air from outdoors and not a closed room – the process becomes extremely noisy in closed quarters. Get a longer air intake pipe or connect a longer air hose to it so that you can transport it to open space, like a backyard. Worth the effort, right? Make sure you pick the accurate pipe thread size for your compressor’s air intake head.Īnother trick is to move the air intake component of the compressor to open space, preferably outdoors. This technique might seem complicated but could chop around 2 to 4 decibels off the noise slab. The gadget contains a silencing tool and an air filter. Install an intake muffler on the air intake pipe. A little tweaking with that part can give you the desired results. The noise of air intake is the loudest, so you need to deal with that component first. Now that you know what makes an air compressor noisy and when the noise level goes beyond the tolerable limit, we will give you some easy and affordable cheats to shut your air compressor up. So, now you know when it gets too loud for comfort. Not to mention the noise explosion will make you deal with whiny and pissed neighbours. According to OSHA, extended exposure to 85dB loudness will leave you completely deaf. However, most cheap air compressors or 1HP units usually have around 80 to 90 dBA or even higher. This much loudness is acceptable, especially in a home environment. When to call the noise level beyond the threshold of tolerance? An air compressor making below 70dBA noise is tolerable because volume ranging from 60 – 70 dB sounds something between a regular conversation and a classroom chatter. Generally, dual-piston compressors – reciprocating compressors – are notorious for being the loudest. Some most common causes are friction, vibration of the machine, use of cheap parts, air intake and exhaust components, placement of the air compressor, and type of the air compressor. Before you jump to noise-reduction tips, you need to know about the factors responsible for the obnoxious loudness of your air compressor.
