Model 313 and 323 -Absorptive Mufflers
Model 313 mufflers; Straight through circular design with absorptive acoustic liner, but without a center bullet. No obstructions in the airstream. Good for smaller diameter connections and when low pressure drop is important. Model 323 mufflers; Circular design with acoustic liner and a center bullet when substantial noise reductions are required. Aerodynamically designed for maximum attenuation with minimum pressure drop.
