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. The Steam Exhaust Muffler is not designed for permanent installation on boilers.
