 Acoustical
silencer nozzles for Tri-Stack™ systems
attenuate up to 12 dBa for quieter operation
in particularly noise sensitive areas. Low
profile design is
unobtrusive, enhancing roofline aesthetics
without affecting fan performance. Acoustical
silencer nozzles may be retrofitted onto
existing Tri-Stack fans quickly
and conveniently. |

*These values include corrections for breakout noise from the motor and nozzles. They do not include breakout noise from by-pass dampers at mixing boxes. In order to achieve the full values listed above, the bypass dampers must also be acoustically treated. |

 Standard Outlet Silencers
Standard silencers are an alternate to the Acoustical Silencer Nozzle™. Like the acoustical silencer nozzle, it att attenuates the Tri-Stack™ system. Standard silencers are available in a variety of lengths for every Tri-Stack model. |
