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.

Discharge Silencers are essential to good system performance on all rotary blower systems. The belief that the discharge creates less noise than the inlet is erroneous because the discharge pulsations and noise are normally contained in a closed system.

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

Application
Blower Discharge Silencer for standard 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
pulsations and excessive high frequencies through the process of converting noise
energy into heat. D32 and D32H 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.

If you are looking for standard silencing for your positive displacement blower the D32 model is a sensible choice. The D32T model still offers the same reliability as the D32 model but can be built with a nozzle configuration to better suit each application.

Application
Combination Intake-Discharge Silencer for Rotary Positive Blowers where maximum silencing is required.

Design
A combination intake and discharge silencer which enables the blower and motor to be mounted directly to the top of the horizontal mounted silencer. The silencers are of a multi-chamber design containing a high frequency absorption section in addition to a special arrangement of volumes and air passageways to effectively reduce both pulsations and high frequencies.

Construction
All welded steel and plate construction for long service life. Acoustic material temperature rating shall not exceed 300°F. Intake and discharge flanges are drilled to match 125 ASA flanges. When specified, the blower flange connections are drilled to match blower flanges or flexible connectors. Blower base, motor base, and mounting brackets are included as integral parts of the silencer package. Blower and Motor Slide Rails are not included with silencer bases. Special designs, relief valve connections and drilling of flanges are available upon request.
