Installation and Maintenance
DUCTMASTER BIFURCATED
Construction
NuAire DuctMaster attenuators for Bifurcated units
are manufactured with a rigidly constructed,
cylindrical galvanised steel casing. The casing is lined
internally with sound absorbent material which has
excellent acoustic properties, is non-hygroscopic and
also incombustible. The material is retained by a perfo-
rated aluminium liner.
Each silencer has two opposed mounting pads with
multiple mounting feet fixing points.
Flanges are quickfit type to match the DuctMaster
Bifurcated axial fans.
Four mounting feet, feet fixings and a clamping collar
are supplied with each silencer.
When a pod is fitted it is constructed of perforated
aluminium with an infill of the acoustic material.
Silencer Types
Two types of cylindrical silencer are available:
Unpodded : Ref = DCS
Podded : Ref = DCSP
(The introduction of the pod considerably improves
the attenuation but increases resistance to airflow).
Two standard lengths of silencers are available:
Short : Ref = S
Long : Ref = L
Examples:
a) DCSP 315 S is a short silencer with a pod.
b) DCS 315 L is a long silencer without a pod.
