If you’re looking for a way to quiet down your oilless air compressor, you’re in luck! Here, you’ll discover the best materials to use for this purpose and the best method for measuring noise levels. In addition, you’ll learn about noise mufflers, which are a great option for reducing noise levels from your oilless air compressor. Keep reading to learn how to quiet your oilless air compressor!
Noise reduction options
If you are concerned about the noise of your oilless air compressor, you may want to consider making a few modifications. For example, you can cover the motor with a sound blanket to absorb piston-cylinder sounds. You can also install rubber grommets to secure the motor, which also acts as a sound absorber. This type of modification will have minimal effect on the performance of your compressor. But, it will certainly help in reducing noise levels.
The noise level of an air compressor can be measured in a standardized manner. This can be done in a room that does not have any walls. Other methods of noise measurement use sound intensity scanning. Noise intensity is influenced by the size of the room, the materials of the walls and ceiling, and the presence of other equipment. Lastly, the positioning of the air compressor can also affect its noise level. The more it vibrates, the louder it is perceived.
Materials used to quiet an oilless air compressor
The materials used to quiet down an oilless air compressor can be as simple as wrapping the motor in sound deadening material. This will reduce vibration noises caused by the piston cylinders. You can also install rubber grommets to secure the motor. Rubber is an excellent sound absorbent. Generally, an oilless air compressor will be quieter than its oil-based counterpart. For more effective noise reduction, you can also invest in a noise-proof box.
For the most affordable solution, you can build a soundproof box. You will need to measure the diameter and height of the air compressor before cutting the plywood or any other soundproofing material. Once you have the exact dimensions of the box, you can begin construction. Once the box is complete, you can then fit in the soundproofing material. Next, install hinges on the front side of the box and a lock system on the opposite side.
Methods of measuring noise level
A standardized way to measure the noise level of an oilless air compressor is to take measurements in an acoustic free field without walls and with a sound intensity scanning technique. The level of noise that an air compressor makes depends on several factors including the size and materials of the room, the presence of other equipment, and the positioning of the compressor within the room. The noise level of an oilless air compressor will differ depending on its size, setup, and connection of its components and pipes.
First, the location of the compressor is important. The unit must be located in an area with minimum noise pollution. The noise is typically measured at a distance of 1.5 meters from the unit’s exhaust. In the case of a portable compressor, a windscreen must be used if the air-conditioning unit is located outdoors. A windscreen can be used to reduce noise, but it must not influence the A-weighted sound level.
Noise mufflers
When you are working in an environment where you can’t hear your employees clearly, you may want to consider installing noise mufflers for oilless air compressedors. This is a simple way to reduce the noise level of an oilless air compressor. Silencers are similar to mufflers for cars, reducing airborne noise from an engine without compromising performance. Unlike a car muffler, a noise muffler for an oilless air compressor incorporates an air filter and silencing component.
The main source of noise for an oilless air compressor is its intake and exhaust ports. Intake noise is low-frequency, and a muffler with a high-impedance composite will reduce the noise. The exhaust noise comes from the outlet port, where air pressure is high and flow velocity is high. Therefore, a muffler with a small hole is required. In this way, the noise muffler can reduce the noise levels from an oilless air compressor significantly.
Noise absorbing blankets
When attempting to quiet down an oilless air compressor, you’ll find that the most effective solution involves covering it completely. This is possible with noise absorbing blankets. They work by absorbing sound and are easy to install. However, you should be aware that the sound blanket can only work as effective as the compressor itself. If it doesn’t fully cover the compressor, you may need to buy a new one. Make sure to look for the noise level and customer feedback before you purchase an air compressor.
To help quiet the noise of an oilless air compressor, you can install sound blankets around the motor or piston cylinders. Sound blankets absorb mid-range and high-frequency sounds and can be placed over the compressor itself or on the walls. If you don’t have the luxury of an enclosure, you can purchase rubber grommets to cover the motor and quiet it down. Rubber is also an excellent sound absorber.
