The RT 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.

RT 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 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.
