Application Data
The effective and economic solution for sound attenuation in circular duct systems from 100 to 500mm diameter. With at least three models per size throughout the range the system designer is given complete flexibility of choice allowing a selection which is the best balance of attenuation, size and cost for any application.

Sonex Attenuators are fitted with a patented duct seal which enables leak free ‘plug-in’ connection to rigid ductwork with consequent savings of installation costs. The excellent attenuation characteristics of the Sonex range are achieved without imposing undue system resistance. Pressure losses are little more than those which would occur over a comparable section of straight duct.

Developed and refined in one of the most modern and comprehensively equipped facilities in Europe. Production samples are regularly re-tested at these same laboratories and we guarantee that Sonex Attenuators will perform to stated figures as a minimum.

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. Standard models have a 30 minute fire rating (60 minutes also available).
