Configuring a Silencer

A silencer may consist of single or multiple silencer units (2 full units illustrated at right). Each full unit consists of two acoustic half-baffles and a central air passage. A silencer may be made up in several configurations using different unit sizes. A silencer with dimension 'M' of 24 in. (610 mm) can be made from one 24 in. (610 mm) unit, or 12 in. (305 mm) units.

*All Kinetics silencers are backed by independent testing in a NVLAP accredited laboratory in accorance with ASTM E477-06a and AMCA 1011-03.
