Stoddard D33-H 2.5" Sfilencer

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 and D33H Silencers 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.
