Fantech's N2T series rectangular attenuators with 200mm thick tapered splitters are available to suit a variety of applications and duct dimensions. They can be made in different widths and heights, and each model number denotes a different percentage of open area and length combination. They provide superior insertion loss and pressure drop performance over standard rectangular attenuators.

The N2T series with 200mm tapered splitters are ideal for general HVAC purposes and suitable for industrial applications.

The N2..QS rectangular Q-Seal tapered attenuator includes the qualities of the N2Tseries attenuator and incorporates an infill system protected by an impermeable plastic membrane/film.

The N2..QS series is suitable in medical and clean room applications and any sensitive ventilation systems requiring an infill material that prevents the possibility of insulation fibre ingress into the airstream.

Fantech's N3T series rectangular attenuators with 300mm thick tapered splitters are available to suit a variety of applications and duct dimensions. They can be made in different widths and heights, and each model number denotes a different percentage of open area and length combination. They provide superior insertion loss and pressure drop performance over standard rectangular attenuators.

The N3T series with 300mm tapered splitters are ideal for general HVAC purposes and suitable for industrial applications.

The N3T..QS rectangular Q-Seal tapered attenuator includes the qualities of the N3T series attenuator and incorporates an infill system protected by an impermeable plastic membrane/film.

The N3T..QS series is suitable in medical and clean room applications and any sensitive ventilation systems requiring an infill material that prevents the possibility of insulation fibre ingress into the airstream.

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.

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.

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.

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.

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

The RT (standard model) rectangular attenuators are also available in a wide range of dimensions (see below)

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.
