You’re probably utilizing an air compressor if you already own or hire home repair tools like crushers, sanders, nail guns, and spray paints. These compressors come in a variety of sizes, from little pancake compressors to massive machines that will be adequately noisy.

how to make an air compressor quiet

While buying one of the latest ultra-quiet air compressor units that are intended primarily for quieter operation is the easiest approach, some people may prefer a DIY answer to quiet down their current compressor.

We’ll look at how low-noise compressor producers conceal the noise that their machines make and see if we can adapt any of the design characteristics to substantially lower the noise of the device we already have. Let’s dive into the details of how an air compressor produces noise, and what could be the potential reasons behind it.

Causes of Noise in an Air Compressor

The level of noise in an air compressor is influenced by several elements. If those are the concerns in your case, you should be able to silence the air compressor easily. The following is a list of the things that influence the sound.

Vibrations

The vibration of the entire machine is the first and most basic source of increased sound in an air compressor.   An air compressor’s vibration is mostly determined by the fitting and kind. There’s a good probability that if you put the air compressor together incorrectly, it’ll start vibrating a lot. The noise level rises if any portion of the machine is not correctly connected to the compressor.

Material of the compressor

The raw materials required in the manufacture of an air compressor are crucial. For example, if you buy a low-cost device made of thin metal parts and use it at home, you can expect it to produce a lot of noise. The reason for this is because when metal is thinner, it vibrates more and produces more noise.

On the other side, several well-known brands manufacture air compressors using high-quality materials. Only strong, high-quality metal is used in their construction. It will vibrate less because of this. As an outcome, the noise level stays within acceptable limits.

Placement

The noise produced by an air compressor is highly dependent on the location in which it is maintained. If you leave the device on a hard surface, for instance, it will most likely create more noise during the execution.

Noise can also be increased by devices that vibrate a lot during operation. In addition, if the surface is uneven, the air compressor will not be correctly set. Ensure that the compressor is placed on a level surface.

The Intake

An air compressor’s intake element is also regarded as a source of the noise. The functioning procedure is comparable to that of a vacuum cleaner. Throughout their functioning, air compressors also use air. This can make a lot of noise.

How To Quiet An Air Compressor

If you’re pondering over how to make an air compressor quiet, there are a few things you can do. We’ll go over the best techniques to reduce sound and keep it at a bearable level in this section.

1. Using Rubber Gourmets

Rubber is a common noise-absorbing substance that is found in a variety of equipment. Stainless steel kitchen basins, for example, have a rubber layer underneath them to reduce noise. An air compressor can be used in the same way.

The rubber gasket must be positioned in between the air compressor and the area where it will be used. When you use the air compressor again, the rubber will reduce vibration and hence reduce noise. The placement of the rubber necessitates precise measurements.

Make sure that when you’ve placed the rubber, the whole thing stays flat. If everything is done correctly, the noise will be reduced. It won’t be completely silent, but the level of noise will be manageable.

2.  Installation of an Intake Silencer

The air intake accounts for a major portion of the obnoxious high-frequency pulsing sound emitted by air compressors. Incoming air is taken past a reed or flapper valve as the compressor turns, which shakes and vibrates with each pulse.

The majority of intake muffling systems are built as a hybrid air filter and silencing gadget. The sound created by the incoming air surge through the filter is muffled by tubes or noise deadening materials, which keep the air compressor’s airflow limitation to a minimum.

You may usually lessen the pulsing noise produced by the air intake system by adding an input suppressor or intake muffler. To buy a replacement air intake filter, you’ll have to determine the pipe thread diameter on your compressor’s intake head.

You could always use a bell reducer and a short pipe tip to insert a larger filter or silencer than necessary, but you should never use an intake filter that limits airflow to your compressors.

Putting the silencing filter solely on a single or two 90-degree street elbows has resulted in calmer results for certain users. Your mileage may vary here; you’ll need to try a few different settings to see which one quiets the compressor the best.

3. Isolate the compressor

Any stiff attachments to the compressor that can emit noise should be avoided. Rubber isolation mounts should be used to secure a static air compressor to the floor. Put a short flexible air hose between the compressor and the stiff piping if you’re using it. There should be no rigid tubing directly attached to the compressor, thus use flexible conduits or rubber cords for power connections.

4. Lubricate the Bearings

It should come as no surprise that any machine with moving elements also has some bearings. An air compressor is just the same way. As a result, when the compressor is operating, the bearings will spin in various directions. There will be some resistance between the metals at that time. If the friction is not effectively controlled, this will result in a lot of noise. Eventually, the metal may corrode, and you will be unable to operate the compressor for an extended period.

Therefore, lubricating the bearings is one thing a user may do to reduce friction and noise. Lubricating metal things is not a tough task. There are a variety of products available for guaranteeing smooth metal-to-metal contact. You can choose the best bearing grease available. Apply the grease as directed and let it rest for a few minutes before turning on the compressor. This is a basic yet efficient noise reduction method.

5. Sound Padding on the Wall

We previously recommended that rubber be placed between the compressor and the solid material. You can do the same with the compressor’s outer walls. The sound will reverberate, and you will hear more noise if you set the compressor near the wall. It can also happen if you place the compressor in a tight space.

As a result, the sound will be reduced by installing anything soundproof on the wall. Rubber grommets are not required in this situation. You can use the soundproof cushioning on the wall instead. In the shops, you will find several sound blankets that will work wonderfully.

You don’t have to cover the entire wall of the room where the compressor is located with cushioning. Instead, simply connect the padding to the compressor’s adjacent wall to prevent sound reverberation.

6. Build a soundproof air compressor box

Making an air compressor quieter can readily be achieved by building a DIY soundproof container or sound dampening shell to enclose the entire compressor.  Place sound-absorbing material on all the sides, roof, and bottom to create a soundproofing enclosure for your compressor to collect part of the noise. To absorb noise on a shoestring, hanging ceiling acoustical tiles can be used.

Sound is effectively blocked by concrete blocks with gaps filled with sand. On the Web, you may find a variety of silent compressor box options, including whole compressor rooms with structure, numerous layers of drywall, and sound numbing insulation batts, as well as plywood boxes, disused freezers, and even storage boxes.

Whatever you do, don’t block the airflow surrounding the compressor; otherwise, it may heat and potentially burn out or catch on fire. Adding an exhaust fan or other methods to draw in cooler air and expel the heat generated by the compressor will be necessary.

7. Cover the compressor with a soundproof blanket

If you are still wondering how to make an air compressor quieter, this is another great method to lessen the noise. You can cover the compressors if you can’t connect sound-absorbing material to the wall or build a soundproof box. You’ll need a soundproof blanket for all this. The blanket should be used to cover the entire compressor. Like a soundproof container, this will keep the noise within.

8. Place the air intake outdoors

As previously stated, the compressor, like a vacuum cleaner, requires air intake to function. The most typical cause of increased sound from an air compressor is this. There is no substitute to placing the air intake outside while you desire a tranquil atmosphere at your office.

Most individuals store their air compressors in their garages, homes, basements, and other locations. When you consider the air intake in certain areas, the noise level immediately rises. As a result, the intake should be placed somewhere where noise is not a problem. You could, for instance, use the lawn or a similar well-ventilated location.

You’ll need to transfer the hose outside to install the intake. Use a sturdy bracket to retain the hose in position in this case. After that, you should restart the compressor to see whether it makes any more noise. Interestingly, the noise level has now reached the level of tolerance.

9. Purchase a Quieter Air Compressor Model

If your air compressor is outdated and you haven’t been able to solve the noise problem with the solutions above, you may want to consider purchasing a new one. Consider the compressor’s maximum noise level while purchasing a new item. You should also study some consumer comments to get a sense of how well you’re doing.

Ensure that the air compressor’s peak noise level does not exceed 70 decibels. This is not an unacceptably high amount. You are free to continue working within this sound range.

Safety Measures To Silence Air Compressor

Always keep safety in mind while making any adjustments to Silence Air Compressor . If you make hazardous alterations to your apparatus, compressed air can be quite deadly.

Ensure that all safety relief faucets are in excellent operating order and installed. Do not raise the pressure switch’s maximum PSI setting. The air intake should not be restricted excessively. It’s also crucial not to block cooling vents or limit airflow all around the compressor. After you’ve finished using a mobile compressor for the day, make sure to unplug it and drain the air tank.

How loud are Air Compressors?

Air compressors aren’t exactly silent when it comes to powering the gadgets they perform. Your compressors might be 40 dB if you’re lucky. Larger, heavier devices can reach a decibel level of above 90.

Many lawn mowers have a decibel level of 90, however, an airplane taking off from the runway has a decibel level of 140. Ear damage is a possibility at that volume. Even extended exposure to items with decibel levels between 80 and 90 could cause hearing damage.

 It won’t happen immediately, but if you use your air compressor frequently enough, you can lose your hearing sooner than you think.
