ATOMUFFLER ® AND BANTAM™ DESIGNS FOR NOISE CONTROL BY THE ALLIED WITAN COMPANY
The Atomuffler’s radical, full-flow design uses interposing sound waves, multiple-stage velocity deceleration, an obstruction-free expansion chamber and a porous disseminator (filter element) to completely dissipate harmful air exhaust blasts. A large peripheral exhaust surface area diffuses the air blast, further lowering velocity and reducing air noise. The Atomuffler is ideal for reducing Exponentially Perceived Noise (EPNdB).
Stop Noise Before it Starts The deafening roar of air exhaust isn’t just distracting – it also can be dangerous. Eliminate the noise and help keep employees safe with the Atomuffler ® and Bantam™ designs for noise control, offered exclusively by the Allied Witan Company.
How They Work The Atomuffler and Bantam muffler and filter product lines eliminate excessive noise by dividing the air stream and turning it back on itself. As air exhaust enters the muffler at high velocity, the Atomuffler and Bantam mufflers redirect it into smaller air streams that rebound off opposing walls of the chamber. With the air steams colliding head-on with each other, the velocity is reduced and the air is dispersed throughout the disseminator surface area. This technique eliminates noise without sacrificing machine performance.
How They Help For more than 60 years the Atomuffler has been used in thousands of plants and countless applications, and the Bantam muffler has proven itself time and again for more than 40 years. They both have an outstanding ability to eliminate excessive noise for a more pleasant working environment while reducing potential physical injuries caused by extreme air blasts.

Air Dryer Muffler
Dual-stage filter element traps particulates for longer element life and less noise The Atomuffler® Air Dryer Muffler is designed specifically to manage the demanding service problems associated with desiccant regenerative-type air dryers. These air dryers often expel air laden with moisture which can be heavily contaminated with desiccant dust. The primary stage of the Air Dryer Muffler’s dual-stage filter element traps particulates, allowing cleaner air to permeate freely through the secondary stage, which manages the reduction of noise. This design also features a relief valve that is triggered to open if the air outflow becomes obstructed by a build-up of particulate, which will divert the outflow directly to atmosphere. It is highly recommended that the air dryer system be initially purged of free desiccant fragments before installing a new Air Dryer Muffler or whenever an air dryer has been recharged with new desiccant material.

Vacuum Pump Exhaust Muffler
For quiet and efficient pump performance Designed to muffle the distracting noise of vacuum pump exhausts, the Atomuffler® Vacuum Pump Exhaust Muffler is an efficient and inexpensive addition to any pump. Noise reduction is achieved by an obstruction-free expansion chamber that reduces exhaust air velocity and softly disperses it throughout the muffler’s large disseminator surface area without causing mechanical impedance. The Vacuum Pump Exhaust Muffler is recommended for applications where quiet and efficient pump performance is critical, such as in suction apparatuses, vacuum frames, checks, simulation chambers, and transfer and control devices.

Defogger Muffler
Unique sump drains out oil mist The Atomuffler® Defogger Muffler is specifically designed to reduce pneumatic noise emanating from air-operated devices and to effectively remove oil mist. This muffler utilizes a comprehensive approach to intercept, extract and condense oil to liquid droplets, which gravitate into a sump to be drained off periodically. The muffler’s design requires that it be mounted with the drain cock pointing downwards, which can then be opened periodically to empty out the sump.

Steam Exhaust Muffler
Boiler start-ups and food processing The Atomuffler® Steam Exhaust Muffler provides a lower cost alternative and effectively silences objectionable noise created by steam exhaust outlets during boiler start-ups and testing stages only. Using readily available replacement disseminator elements, Steam Exhaust Mufflers can be completely rebuilt and ready for the next start-up or tuning job. Constructed of corrosion-resistant materials, the end caps are also treated with a special epoxy coating for additional resistance to conditions where alkalis are a problem. This also makes the Steam Exhaust Muffler well-suited for low-pressure food processing and similar applications. Note: The Steam Exhaust Muffler is not designed for permanent installation on boilers.

Damper Muffler
Easily handles dirt and moisture-laden air Featuring the same outstanding design as the industry-standard Atomuffler®, the Damper Muffler includes an added variable reactive damper that provides an unobstructed free-flow air passage to reduce noise caused by emanating raw exhaust air. This unique design utilizes a proven reactive principle of noise suppression. The explosive force of exhaust air impacting against the damper thrusts it into an oscillating motion, converting dynamic acoustic energy into kinetic energy. The damper’s responsive pulsating motion drains off kinetic energy hence dissipating acoustical energy. Some applications include foundry equipment and railway and transit brake systems.

MICRO MINIATURE MUFFLER
Micro Miniature Muffler Adjustable control for logic applications Allied Witan Company’s Micro Miniature Muffler is designed specifically for low air volume use on pneumatic logic applications such as control, pilot, limit, zone, and relay valves. The muffler’s compact size allows installation in extremely tight quarters. Attached directly to exhaust ports, noise reduction is accomplished by dispersing the exhaust air radially, minimizing sound intensity with negligible flow impedance. The Micro Miniature Muffler also can be used as a speed control to meter exhaust air flow.

M64 Mini-Muff High flow in a compact package The M64 Mini-Muff combines the serviceability of our Atomuffler® products with the compact size and durability of our all-metal Bantam™ mufflers. Constructed entirely of corrosion-resistant metals, the standard M64 Mini-Muff allows for higher temperature operating conditions. Back pressure is kept at a minimum thanks to a large unobstructed inlet and exhaust surface area. All stainless steel construction is also available for very corrosive or sensitive situations. This model has a 2” pipe thread and is easily attached directly to the exhaust ports of air-operated equipment.

It is widely recommended by leading noise consultants and safety engineers throughout the world. When you specify the Atomuffler, you can be confident you’re getting the ultimate in noise reduction, advanced muffler design, exceptional service and value.
How much noise is too much? r /PJTF MFWFMT JO UIF VQQFS EFDJCFM E# SBOHF BSF BOOPZJOH UP TPNF QFPQMF r &YQPTVSF UP MFWFMT BCPWF E# GPS IPVST DBO QPTTJCMZ DBVTF EBNBHF XIJMF damage is likely when exposed to levels above 90 dB for the same amount of time. r 8IFO MFWFMT BSF BCPWF E# GPS IPVST TFSJPVT EBNBHF JT QPTTJCMF r E# JT DPOTJEFSFE UIF IVNBO UISFTIPME GPS QBJO BOE FBSESVN SVQUVSF DBO occur at 150 db. Damage caused by noise goes beyond just hearing loss. Recent studies have shown that increased exposure to high levels of noise can cause stress, hypertension, and even cardiovascular problems. Tests performed on air exhausts not equipped and equipped with the Atomuffler showed that noise levels can drop from 97-121 dB without a muffler down to 81-84 dB with the Atomuffler. 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 of predicting exact results.
