Introduction
Scope of Manual
This instruction manual provides installation,
maintenance, and parts ordering information for the
NPS 2 through 12 Fisher WhisperTube modal
attenuator.
Description
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 fluid flow rates,
pressures and temperatures.
Do not install, operate, or maintain a 6060 WhisperTube without being fully trained and qualified in
valve, actuator, and accessory installation, operation, and maintenance. To avoid personal injury or
property damage, it is important to carefully read, understand, and follow all the contents of this
manual, including all safety cautions and warnings. If you have any questions about these instructions,
