Sound attenuators permit the passage of air while reducing noise in ventilation systems.
Which sound attenuator do I use?
NCS Acoustics design, manufacture and install many types of attenuators, including; Rectangular, Cylindrical and Specialist. We have standard sizes readily available and are also manufacture to individual requirements. See below for a description of each type and read the brochures for more information or call us and let our expert acoustic engineers provide you with suitable options and a quote.
NCS Acoustics have developed an Attenuator Selection Program, software that helps you to identify the right attenuators for you needs. Covers the NCS, NSM, NCT, NTM ranges, lengths from 600mm to 3600mm. Contact us about this.

Projects:
Curb Rectangular Attenuators
Our Curb Rectangular Attenuators are similar to NCT/NCS Rectangular Attenuators but with a spacer for fan clearances and a flashing for roof exit and weather protection.
Contact us for more information.
HVAC Cylindrical Attenuators
For reduction of ventilation and air conditioning system noise in numerous applications. Designed for direct connection to the inlet and outlet of axial flow type fans and can be adapted for induct applications. Melinex lining avaialble for damp or grease-laden air applications.
FCU Attenuators
FCU Attenuators provide optimised acoustic performance for reducing inlet/outlet sound levels from ceiling mounted FCU units where high levels of noise reduction are required and space constraints govern, such as residential and hotel HVAC applications. Client specified spigot sizes for easy connection to FCU unit and ducting. Standard sizes 600mm & 900mm long and custom widths manufactured to individual requirements.
Powered Attenuators
Custom designed powered unit, with attenuation and fan to simplify ventilation, prefect for plant rooms.
