How can I choose a quiet compressor?
Selection of a quiet compressor requires the internal mechanism of machine compression, type of lubrication and energy sources. Another factor to keep in mind when choosing a quiet compressor is the total size of the machine. Some compressors manufacturers offer external cladding machines to prevent excessive noise generated from the internal engine. In addition, you could buy one of the specialized compressors that their manufacturers consider to be "quiet" who have noise outputs of about 30 decibels. This quiet compressor uses two large inner screws that are set parallel to each other; When he turns at the same time. The air entering into the compressor is captured in moving grooves. As the mechanism rotates, a larger volume of air is compressed into the tank. To compress the connected air tool or the compressed air receives this compressed air and uses it to generate mechanical movement.
Compressors are available in versions without oil and oil; But the calm compressor will be oiledcompressor. The lubrication provided by the oil dampens the compressor engine noise. Oil -free compressors have more friction because the engine works because their pre -lubricated internal coating does not provide much noise reduction.
The energy source is another factor that you should consider when buying a quiet compressor. These machines are offered in electric or gas versions; Many experts agree that electric compressors are much silence than gas. Although the engine still generates noise during basic operation, electric hum is not as disturbing as the combustion processes in the gas compressor that is similar to the sounds of the car engine.
Generally, the large size of the compressor will require a larger engine that generates more noise. A quiet compressor will usually be a smaller model like a portable product. A small engine in a portable compressor cannot produce a lot of noise because the operating mechanIsms such as pistons moving in cylinders are much smaller and move in a more limited area compared to a larger compressor.
Some manufacturers produce and sell what a quiet compressor calls. These compressors may be expensive because the physical design of the tank and surrounding cases is stronger; This design function dampens the noise produced by the machine. You should remember that these compressors are not quiet, but have a very low audio output.
