Rectangular Attenuators with Tapered Splitters – NTA20C

The NTA rectangular attenuators are available in a wide range of dimensions. They have tapered splitters which provide a lower noise reduction in comparison to straight splitter variants, but have a lower static pressure loss across the attenuator.

NTA AirLay models use a revolutionary polyester acoustic infill which is made from 70% recycled plastics. It provides greater insertions losses across the most critical frequencies when compared to conventional infill materials. Airlay is suitable for dry general HVAC applications with temperatures up to 80°C.

The NTA rectangular attenuators use cases and splitter frames made from durable galvanized sheet steel as standard.
