Sound Attenuator

 
GENERAL
ARSA has been developed to meet todays high requirements for sound attenuation and is especially suitable for use in duct systems.
 
QUICK FACTS
  • Rectangular sound attenuator with connections equal to outer casing
  • Good aerodynamic characteristics
  • Low pressure drop due to tapered splitters
  • Environmentally friendly sound attenuating material: Mineral wool with Soundtex
  • Available with inspection hatch
  • Available in fire-insulated version with 50 mm mineral wool insulation
  • Washable surface Soundtex
  • Connection dimensions from 400 x 300 to 2200 x 2200 mm
  • Customized design to suite any site requirements
DESIGN
  • ARSA is manufactured as standard in galvanized steel sheet.
  • The sound attenuating material, Soundtex, is tested to ISO standards with regard to cleaning, fibre-loosening, ageing properties, wet cleanable, emissions etc.
  • ARSA is supplied as standard with Flanged connection to connecting ducts.
FUNCTION
The low pressure drop through ARSA is achieved by shaping the splitter elements in accordance with the basic laws of aerodynamics using continuous tapering. The low pressure drop may be exploited to:
  • ARSA is manufactured as standard in galvanized steel sheet.
  • The sound attenuating material, Soundtex is tested to ISO standards with regard to cleaning, fibre-loosening, ageing properties, wet cleanable, emissions etc.
  • ARSA is supplied as standard with Flanged connection to connecting ducts.
ARSA contains all the positive characteristics of highest standard sound attenuators. By taking into consideration the properties of the construction materials and utilizing the basic principles of flow theory, Aircoustics have optimized the sound attenuator with regard to:
  • The acoustic properties of the sound attenuating materials
  • The thickness of the splitters
  • The width of the slots
  • The length of the splitters
  • The surface covering
  • Cleanabillity
By combining the above factors, Aircoustics can always offer the best sound attenuation and lowest pressure drop according to customer requirements.
 
Model ACSA - Sound Attenuator
 
 
FUNCTION
ACSA is a circular sound attenuator for use in circular ducts with 100 mm glass wool insulation for optimum sound attenuation. Availabel with a centre body for extra high attenuation and with flange connection. Fire insulation to E30 standard.
 
QUICK FACTS
  • Wide product range
  • Very high attenuation
  • Aerodynamically shaped centre body
  • Fiber-safe surface layer
  • Available with flange connection
  • Connection diametres from 100 to 2000 mm
DESIGN
ACSA is a circular sound attenuator for connection to circular ducts. The sound attenuating material consists of glass wool, which gives very good sound attenuation especially in the middle frequencies. The sound attenuating material consists of 100 mm longfibred glass wool which is covered with a layer of Soundtex. This material can resist considerably higher air velocities and mechanical wear than the standard fibre commonly used by other manufacturers. The sound attenuating material is also covered with perforated steel sheet over the Soundtex.

ACSA is manufactured as standard in galvanized steel sheet. The connection spigots are equipped with rubber seals.

ACSA fulfils fire class E30.
 
ACSA -P Sound Attenuator
   
DESIGN

ACSA -P is a circular sound attenuator, equipped with an aerodynamically shaped centre body. ACSA-P are intended for connection to circular ducts. The sound attenuating material consists of glass wool, which gives very good sound attenuation especially in the middle frequencies. The sound attenuating material consists of 100 mm longfibred glass wool which is covered with a layer of Soundtex. This material can resist considerably higher air velocities and mechanical wear than the standard fibre commonly used by other manufacturers. The sound attenuating material is also

covered with perforated steel sheet over the Soundtex.

ACSA-P is manufactured as standard in galvanized steel sheet. The connection spigots are equipped with rubber seals.

ACSA-P fulfils fire class E30.

Dimensions from 315 to 2000 mm are available on order.

Customized sizes also available on request to suite any site requirement
