Circular silencers - Model 213 and 223
industrial grade, all welded construction

Applications

• Fan inlet and outlet silencers
• Pressure blower silencers
• Intake silencers on engines
• Exhaust stack silencers
• Ventilation intake and discharge silencers
• HVAC duct silencers

Model 213 silencers

• Straight through circular silencers with acoustic liner, but without a center bullet
• No obstructions in the airstream
• Good for smaller diameter connections and when low pressure drop and economy are priorities

Model 223 silencers

• Circular silencers with acoustic liner and a center bullet when substantial noise reductions are required
• Aerodynamically designed for maximum attenuation with minimum pressure drop
• When used on inline axial fans, we can fine tune the center bullet so that it matches the fan hub diameter, reducing pressure drop by as much as 50%

Accessories

• Galvanized and stainless steel mesh bird, insect and safety screens
• Drilled flanges matched to the connecting equipment or ductwork
• Mounting brackets, support legs, saddles and feet for silencer installation
• Access panels and doors for inspection of internals
• Variety of fabric, film and mesh baffle liners available for different types of service
• Pressure and flow measurement devices including pressure taps, rings and piezometer tubes

Circular silencer features

Design options

• Cleanable and removable liner/bullet designs for dirty applications
• Tapered transition/evase silencers for use on axial flow fans and for attenuation in restricted spaces
• Insert silencers (liner, bullet and support structure, without casing) for installation in pre-existing ductwork and stacks
