Stoddard Silencers :: Stoddard Silencers D33 T
Application
Blower Discharge Silencer for maximum silencing at blower speeds above transition speed.
Design
A multi-chamber silencer containing a high frequency absorption device in addition to a
special arrangement of volumes and air passageways to effectively reduce both pulsation
and excessive high frequencies through the process of converting noise energy into heat.
D33 Silencer may be installed horizontally or vertically. Design parameters permit
nozzle orientation to suit installation requirements.
Construction
All welded steel sheet and plate construction for long service life. Acoustic absorption
material temperature limits far exceed application temperatures. Exterior surfaces are
prime coated. Flanges are drilled to match 125 lb. American Standard Flanges. Inspection
openings, mounting brackets, relief valve nozzles or special paint are available at extra
charge
