• Providing up to 85% perceived noise reduction and a 94% flow coefficient.

• Professionally reduces the Effective Perceived Noise in Decibels (EPNdB) without compromising equipment performance.

• Designed to absorb explosive exhaust noise emitted from valve exhaust ports, while muffling it through an optimized constant velocity (CV) flow coefficient.

• Exhaust gases are gently discharged into the atmosphere without noise, oil mist, or other pollutants, helping to maintain a clean, comfortable, and efficient working environment.

• A professional laboratory is set up based on the customer's actual usage scenarios. The product itself features corrosion-resistant aluminum end caps, 430 stainless steel components, high-temperature resistant fiberglass silencing wool, and ultra-fine fiber felt, ensuring resistance to chemical corrosion.

• Recommended for general exhaust up to 232 PSi (16 bar) and should be used to stop noise before it stops.

• The deafening exhaust sound not only distracts attention but can also be very dangerous. 

  The silencer made by Yuanmei is used to control noise and help ensure employee safety, meeting the requirements of noise control and filtration.

How do they work

Reduce excessive noise by separating the airflow and turning it back by itself. When the air is discharged and enters the muffler at high speed, the Yuanmei muffler redirects it to smaller airflows, which rebound from the opposite walls of the muffler chamber. When the airflow collides head-on, the speed will decrease and the exhaust gas will be gently dispersed over the entire surface area of the diffuser. This technology reduces noise without sacrificing machine performance.

How do they offer help

In thousands of factories and countless applications, the silencers of the Yuanmei brand have been in use for over 10 yearstime and again proving their effectiveness, value and advantages.They have an excellent ability to control excessive noise to achieve a more comfortable workingenvironment while reducing the possibility of personal injury caused by extreme air currents.

Noise Information - How much noise is considered too loud?

Noise levels within the range of 70 decibels (dB) can be quite annoying for some people.

Exposure to a level above 80 decibels for 8 hours may cause hearing damage, while exposure to a level above 90 decibels for the same period of time may also cause hearing damage.

When the noise level exceeds 100 decibels and persists for 8 hours, it may cause severe hearing damage.

120 dB is regarded as the threshold for human pain, and tympanic membrane rupture may occur at 150 dB.

The damage caused by noise is not merely hearing loss. Studies show that continuous exposure to high levels of noise can lead to stress, high blood pressure, and even cardiovascular problems.

For example, testing of exhaust pipes without silencing products has shown that noise levels can be reduced from 49.3-113.6 dB with no silencer to 76.1 dB with the Yuanmei brand. This was reduced by a maximum of 37.5 dB. 

On average, the noise level was reduced by 5.35 dB dB. However, this is just our experimental data, because each application is different and cannot predict exact results, we can only show you our own experimental results.

Compared with famous brands, our products are not inferior to them at all.
