Parallel baffle circular silencers - Model 233 industrial grade, all welded construction

 

Applications

  • Fan inlet and outlet silencers
  • Pressure blower inlet silencers
  • Exhaust stack silencers
  • Ventilation intake and discharge silencers

Benefits

  • Usually used in larger diameter, moderate to high velocities, systems requiring substantial noise attenuation
  • Superior choice for use as insert silencers and when small passage widths are required for mid to high frequency attenuation
  • Aerodynamically designed baffle noses and tails guarantee minimize pressure drop

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

Design options

  • Cleanable and removable liner/bullet designs for dirty applications
  • Insert silencers (baffles and support structure, without casing) for installation in pre-existing ductwork and stacks
