S Series (Spigot Connection) Attenuator
A comprehensive range of attenuators with male spigot connections to suit metric spiral ductwork systems.
Available in up to four standard lengths from stock they have excellent attenuation properties. Achieved with sound absorbing acoustic infill which is glass tissue faced as standard to minimise fibre migration retained in the casing with a perforated steel liner.
Melinex lining (no additional cost)
Where moist or greasy ambient conditions exist (kitchen hood or wash extract) or for clean air applications (hospital or test lab). The glass tissue facing should be replaced with a melinex lining barrier. To prevent any particle migration through the inner liner and to protect the acoustic infill from soakage. This will however result in a slight loss of attenuator performance. Please contact our sales office for further information.
