Noise Attenuators

MODEL	TYPICAL APPLICATIONS	SPECIFICATIONS

Series-A	The Series-A Orifice Plate with its drilled orifice pattern is installed after the pressure regulating valve to smooth out turbulence caused by the pressure drop across the regulator. Noise reduction levels of 5-10 dBA can typically be achieved. CATALOG SPEC SHEET(S)	Model: Series-A Noise Reduction Capability: 5-10 dBA Sizes : 2" - 6" Connections: 125# FLG, 250# FLG

Series-H	The Series-H Acoustic Silencer incorporates a Dual Diffuser tube design. The inner tube has a drilled orifice pattern and the outer tube contains an integral layer of sound absorbing insulation. Noise reduction levels of 20-30 dBA can typically be achieved. CATALOG SPEC SHEET(S)	Model: Series-H Noise Reduction Capability: 20-30 dBA Sizes (Inlet x Outlet): 4" x 8", 6" x 10", 6" x 12" Connections: FLG

Series-S	The Series-S Acoustic Diffuser incorporates a single tube with a drilled orifice pattern which reduces downstream turbulence. Noise reduction levels of 10-15 dBA can typically be achieved. CATALOG SPEC SHEET(S)	Model: Series-S Noise Reduction Capability: 10-15 dBA Sizes (Inlet): 3/4" - 6" Connections: NPT, FLG
