E-outstanding Noise Reducer 5PCS 1/4Inch NPT Black Plastic Pneumatic Air Compressor Exhaust Muffler Silencer

Exhaust muffler: In a pneumatic system, the cylinder discharges to the atmosphere through the exhaust hole of the reversing valve. Because the passage of the gas path is curved and narrowed in the valve, the exhaust pressure is higher. When the exhaust speed changes from the speed of sound When the exhaust hole is discharged, the air will expand and the gas will vibrate, and the sound will be harsh. The size of the noise is related to the speed of the driver. The faster the driver, the greater the noise. The sound pressure level at the entrance of 20 PSIG is 67dBA, and the sound pressure level at the entrance of 100 PSIG is 84dBA. Maximum pressure: 10KG The noise is measured in decibels (dB) at a distance of one meter from the exhaust port. According to international standards, the maximum noise allowed during 8 hours of work is 90 db, the maximum noise that people can withstand during 4 hours of work is 93 db, and the maximum noise allowed for two people working hours is 96 db, allowing one hour of work The maximum human noise is 99 db, and the maximum limit is 115 db (increasing half of the time allowed by 3 db). Noise is harmful to human health, it is necessary to install a muffler to reduce unnecessary noise. Generally, the muffler of the solenoid valve can be reduced by about 25dB. Note: (1) When choosing a plastic muffler, pay attention to the surrounding environment (it will not be knocked or knocked), the tightening force should not be too large during installation, and it is not suitable to use organic solvents. (2) Because the cylinder speed is too slow, some users are not allowed to remove the muffler. When the impurities are sucked in from the exhaust, this operation will not only greatly increase the noise, but also cause the valve to change direction.

• Made of high-quality polyethylene and polyethylene foam with long service life.
• With plastic reinforced structure, it can withstand ultra-high pressure without deformation.
• Compact muffler, used to diffuse air and noise from the exhaust port of muffler, gas cylinder and pneumatic tool.
• In a pneumatic system, the cylinder discharges to the atmosphere through the exhaust hole of the reversing valve. Because the passage of the gas path is bent and narrowed in the valve, the exhaust pressure is higher.
• When the exhaust speed is discharged from the exhaust hole at the speed of sound, the air will vibrate after the expansion of the air, and the sound will be harsh. The size of the noise is related to the speed of the driver. The faster the driver, the greater the noise.
