Stop Noise Before it Starts

The deafening roar of air exhaust isn’t just distracting – it also can be dangerous. Control the noise and help keep employees safe with Atomuffler- and Bantam-brand mufflers and filters for noise control and filtering needs, manufactured exclusively by Allied Witan Company and available from Multifactor Europe Limited

How They Work

Atomuffler and Bantam muffler and filter product lines reduce excessive noise by dividing the air stream and turning it back on itself. As air exhaust enters the muffler at high velocity, Atomuffler and Bantam mufflers redirect it into smaller air streams that rebound off opposing walls of the muffler chamber. With air streams colliding head-on with each other, velocity is reduced and the exhaust air is gently dispersed throughout the disseminator surface area. This technique reduces noise without sacrificing machine performance.

How They Help

In thousands of plants and countless applications, Atomuffler-brand mufflers have been used for more than 60 years, and Bantam mufflers for more than 40 years. Both product lines have proven themselves time and again for effectiveness, value and superiority. They have an outstanding ability to control excessive noise for more pleasant working environments while reducing the potential of physical injuries caused by extreme air blasts.

Noise Information – How much noise is too much?

• Noise levels in the upper 70 decibel (dB) range are annoying to some people.
• Exposure to levels above 80 dB for 8 hours may cause hearing damage, while exposure to levels above 90 dB for the same amount of time is likely to cause hearing damage.
• When noise levels are above 100 dB for 8 hours, serious hearing damage is possible.
• 120 dB is considered the human threshold for pain, and eardrum rupture can occur at 150 dB.

Damage caused by noise goes beyond just hearing loss. Recent studies have shown that sustained exposure to high levels of noise can cause stress, hypertension, and even cardiovascular problems.

For example, tests performed on air exhausts not equipped and equipped with Atomuffler products showed that noise levels can drop from 97-121 dB without a muffler down to 81-84 dB with Atomuffler products. That’s a decrease of up to 37 dB. On average, noise levels were reduced 17-25 dB. However, every application is different and there is no way to predict exact results.

From a different perspective - dB and power:

• 3 dB reduction cuts sound energy in half
• 10 dB reduction decreases sound energy by a factor of 10
• 20 dB reduction decreases sound energy by a factor of 100
