MSA1 Legacy Spark Arresting Chamber Exhaust Silencers

MSA1 Legacy Spark Arresting Chamber Exhaust Silencers

Use a model MSA1 in residential and light industrial areas for spark arresting capability where background noise is relatively high and constant and the need for higher degrees of silencing is minimal. In residential neighborhoods having high traffic or light industry with relatively constant background noise. Residents in these areas are typically accustomed to the noise or make some efforts to shield themselves from the ever present background noise. Use of an MSA1 can keep engine exhaust noise within existing noise levels.

Typical Applications: Internal combustion engine exhausts, marine service, refineries/hazardous environments, and offshore drilling/production platforms
