Best Chamber Type Spark Arresting:
Expected Attenuation is 28 to 32 dBA
Use a model MSA4 for the highest degree of silencing in areas requiring “hospital grade� noise reductions and a spark arresting feature.
The MSA4 is presently the top-of-the-line reaction silencer without addition of insulated inlets,
outlets or shells or custom silencer design.
Example: Suitable for use where background noise is extremely low, such as residential or hospital locations away from busy streets.
