FEATURES:

Attenuators have been designed to reduce noise interference between interconnected Space/Rooms. Airflow/Air-transfer is maintained at relatively low resistance whilst limiting high degree of noise transfer.

Four different styles are offered to suit most common configuration of installations.

ATTENUATOR TYPES:

• CAU  : Type CAU commonly used for ceiling to ceiling penetration to   avoid noise interference between interconnected rooms.
• CAI    : Type CAI designed for in-line duct mounting in a ventilation system or simple room to room wall penetration above    ceiling to isolate sound.
• CAL   : Type CAL commonly used for air transfer between adjoining areas where the acoustic integrity of a common partition needs to be maintained.
• CAZ   : Type CAZ can be used for mounting inside wall cavity or in the ceiling cavity.

CONSTRUCTION:

Casings are manufactured from pre-galvanised sheet steel 1.2mm thick with Acoustic material infill lined with erosion resistance film which is retained and fixed with perforated sheet steel.

PERFORMANCE:

Acoustic performance of crosstalk attenuators are derived from tests meeting with requirements of BS4718:1971 and AS1191:1985.
