Blower Discharge Silencer for standard silencing at blower speeds below transition speed.

Design
A multi-chambered silencer containing a special arrangement of volumes and air passageways to effectively reduce pulsations through the conversion of noise energy into heat. D12 and D12H 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. 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.
