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.
