Pod Type Circular Attenuator – VCA-SP/LP Series

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.
