Fisher™ 6060 WhisperTube Modal Attenuator

The WhisperTube is a passive reactive silencer designed for installation downstream of the control valve or other equipment contributing to system noise. Requiring negligible pressure drop across the device; the WhisperTube achieves system noise reduction across a wide range of conditions without impacting the flow capacity or process.

• Broadband Noise Reduction — Patented design with internal acoustic cavities of varying sizes reduce noise across a broad range of frequencies.
• Application Versatility — Designed for a wide range of fluid flow rates; pressures and temperatures. Reduce noise inside the pipe for all sources upstream. Pair the WhisperTube with any equipment used in compressible fluid service.
• Maximize Flow Capacity — Negligible pressure drop across the WhisperTube other than the normally expected line loss for a pipe spool piece of equivalent length equates to noise attenuation with no impact on process flow.
• Passive Reactive Silencer — Internal cavities produce acoustic wave reflections that reduce noise propagating downstream.
• Reliable Performance — No internal acoustic packing material to fail from moisture absorption. Cast internal drain channel ensures any potential liquid buildup can be removed; ensuring optimum performance.
• Compatible with Piggable Systems — Straight through flow geometry with inside diameter that matches the pipe accommodates pigging operations when required for cleaning and maintenance.
• Sour Service Capability — NACE MR0103; MR0175 / ISO 15156 compliant materials of construction as standard for applications involving sour gas or vapor.
• Quick and Easy Maintenance — Removeable cylindrical stainless steel screen for easy cleaning if required with no special tools needed.
• Easy Installation — Threaded lifting provisions accommodate fitting the body with hoist rings or lifting eye bolts for optimized product control during installation.
