Ventilation Duct Silencers

• Over 30 designs
• Wide range of performance options
• Special low frequency, fibre-free and cross-talk models

IAC rectangular and cylindrical duct silencers provide effective, predictable noise reduction at substantial savings over other methods because IAC products are laboratory developed and tested under controlled conditions. Moreover, they are manufactured to specific metal tolerances and with controlled acoustic infill flow resistances to achieve consistent results.

World Leader IAC Launches 'Green' Silencer Range

IAC Limited of Winchester is introducing the first British-made 'green' silencer range for air handling applications. With acoustic infill material made from specially-developed post-industrial organic fibre, IAC is continuing to set the industry standard by providing eco-friendly alternatives to suit today's construction agenda.

• Acoustic fill is manufactured from 100% post industrial recycled organic material thereby reducing landfill
• Offers a solution to today's increasing requirements for eco-friendly HVAC systems.
• Fill requires a minimum amount of energy to manufacture - aiding energy conservation
• Fill easy to handle without skin irritation - therefore worker friendly
• Quiet-Duct Ultra Green silencer fill is mould and fire resistant and
  contains no harmful airborne particulates, formaldehyde or fibreglass to give 'peace of mind' in indoor air conditioned environments.

Fibre-Free 'Packless' Silencers

• Uniquely available from IAC
