The Tubular Duct Silencer is an acoustically effective cylindrical silencer using an absorptive annular flow design to provide high attenuation with minimum associated pressure loss.
The PULSCO TDS is most effective in mid-to-high frequencies, such as noise generated by fans, blowers, compressors, and/or turbochargers.

For any question or concern
Tubular Duct Silencer
The Tubular Duct Silencer reduces unwanted air flow noise and crosstalk conveyed into areas through ducting or piping.
The TDS is a cylindrical silencer that utilizes an absorptive, straight-through design to provide mid-to-high frequency attenuation with minimum pressure loss.
It includes a high transmission loss wall construction, maximum absorptive area, and an efficient aerodynamic design.
Flange
Flanges are drilled to match 125 lb. ANSI Standard (except TDS-2-8L and TDS-3-8L which have male NPT connectors.)
Internal Plate Material
The internal plate is made of 14 gauge perforated carbon steel.
Shell Material
All models up to 26″ are fabricated of 14 gauge hot rolled carbon steel. Models 26″ and above are constructed of 11 gauge hot rolled carbon steel.
External Finish
All Tubular Duct Silencers are finished with our standard primer.
High Temperature
High temperature designs, TDS, are available for applications such as gas turbine exhaust systems. The TDS is custom designed to meet the temperature requirements of your applications.
Acoustical Packing
The acoustical packing consists of 3pcf fiberglass acoustic packing.
