Features
and Benefits
Trane Plus Duct Silencer
The Plus option is a high performance
duct silencer. Designed specifically for
the Super Q II and Model Q
™ , it has
several unique features that reduce
airborne noise and turbulence to
exceptionally low levels. Briefly, the
Plus option develops maximum static
regain while simultaneously limiting
objectionable mid and high frequency
noise. The Plus option should be used
whenever quiet comfort is desired
and the duct system is acoustically
unable to provide it.
Trane’s Plus Silencer provides
significant noise attenuation, up to
32 db at 1,000 Hz, without a significant
increase in fan horsepower
requirements.
Plus Silencer
The modular, component design
approach of the Super Q II air handling
system makes it exceptionally well
suited for renovation, retrofit and
replacement projects. The Super Q II air
handling system components (fan,
silencers, filter/coil module, etc.) fit
through most doors and elevators and
can be easily field-assembled into any
system configuration (blow-thru, draw-
thru, etc.). By carrying the concept of noise source
attenuation to its economic maximum,
Trane has created a fan system that can
move significant amounts of air
without creating objectionable low
frequency rumble. It provides proven
acoustical performance with less
design risk. In project after project, the
Trane Model Q fan has been the key to
creating NC 15 to NC 35 quiet
comfort jobs.
Beyond quiet, the Super Q II Plus
system is small and compact. In fact, it
is small and quiet enough that it can be
successfully installed in ceiling
plenums. Locating a Super Q II Plus in
the plenum helps reduce and even
eliminate the floor space needed for
the mechanical room.
