Features

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

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

Refer to the Q-Seal series for applications where moisture may be present in the air stream.
