Description
These series are rigidly constructed and consist of an outer
cylindrical galvanized steel casing, lined internally with non-hygroscopic and incombustible sound-absorbent material. This
material is retained by an inner perforated metal cylinder.
When a pod is fitted, it is of perforated metal, retaining an infill of
acoustic material.
Melinex lining of the acoustic infill can be provided to prevent the
ingress of moisture or grease. There is a small performance
penalty in higher frequencies with this.
The ends of the silencers are drilled and tapped to match the
VANCO axial flow fans. Non-standard flange drillings or sizes can
be supplied to the customer’s specifications.
