SAF SAC 2-Sound Attenuators Circular

     
Description:

The SAF Model  Circular silencers, in flexible aluminum construction, for the reduction of noise in the circular ducts of air conditioning systems. Hygienically safe due to bio-soluble absorption material according to EU directive 97/69/EC. Variant with spigot has a groove for a lip seal, suitable for circular connecting ducts to EN 1506 or EN 13180. Absorption material is non-combustible and inert to fungal and bacterial growth. Insertion loss measured according to ISO 7235.Casing air leakage to EN 15727, class D.

Application:

• Circular silencers are used for the reduction of noise in the circular ducts of air conditioning systems
• For the reduction of air-regenerated noise of air terminal units and for the reduction of fan noise
• Can be used as cross talk silencer to reduce the transfer of noise through ducts between neighboring rooms
• Very flexible and consequently suitable for installation in complicated duct systems and restricted spaces

Construction:

• Casing and perforated inner duct are Aluminum
• Absorption material: Mineral wool
• Absorption material faced with non-woven glass fiber fabric for protection against erosion due to airflow velocities up to 20 m/s
• Casing air leakage to EN 15727, class D
• Smallest bend radius 3 × outer diameter D₃
• Installation in ducts outside of closed rooms requires sufficient protection against the effects of weather
• Casing with acoustic and thermal insulation.
• Spigot with groove for lip seal
• Maximum operating pressure 1000 Pa
• operating temperature 100 °C
