Sonex Circular Attenuators Series

  Features

• The Q-Tech high performance SONEX circular attenuators are the outcome of a testing and development programme in our insertion loss test facility.
• Developed to provide high performances the SONEX range is designed for several applications.
• Their prime use is for connecting to fans, but they are also ideal for connecting to supply air grilles or being positioned anywhere throughout a system where attenuation is necessary to remove noise generated by equipment.
• In all situations they provide a known and dependable insertion loss, giving security to design engineers looking for quality installations in often difficult to handle situations.

• All units have been tested in accordance with BS4718:1971 for insertion loss.
• Air flow pressure loss data was obtained from tests conducted on a BS848 : Part 1, 1980 test rig.
• Pressure losses are little more than those which would occur over a comparable section of straight duct.

  Construction

• The attenuator consists of a perforated tubular liner manufactured from sheet steel.
• The liner is enclosed by a thick layer of mineral wool sound absorbing material.
• Casing and end plates are formed from galvanised sheet steel.
