Features

The RT..QS (Q-Seal) 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..QS (Q-Seal) models use a bio-soluble acoustic grade glass wool or mineral wool infill, fullw wrapped in an impermeable plastic membrane/film, encased in finely perforated galvanised steel.

They are used in critical applications, medical and clean rooms, and any sensitive ventilation systems requiring a wrapped infill material to prevent the possibility of insulation fibre ingress into the airstream. They are also suitable where the insulation medium is directly exposed to weather, grease, liquid or dusts. Attenuators of this model type may also be cleaned periodically by low-pressure steam or pressure washer equipment.
