The RS 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.

RS models use a bio-soluble acoustic grade glass wool or mineral wool infill, faced with fiberglass membrane, encased in finely perforated galvanised steel. Infill is hygroscopic and incombustible. It is suitable for dry general HVAC and industrial applications.

The RS 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.
