50% reduction in noise energy
Duct Silencers greatly reduce air movement noise levels in your work area or outside the building when located in the duct line on air discharge of fans and dust collectors. Duct Silencers can be installed in new or existing systems. Not to be installed on inlet side of dust collector.
Our Duct Silencer is constructed of three layers. The inside layer is a wall fabricated of 22 gauge expanded metal. This is wrapped in the second layer which is a sound absorbing Melamine acoustical sculptured wedge foam that withstands constant temperatures up to 320oF covered with a hypalon coating. The hypalon coating stops the foam from absorbing contaminate that flows through the duct system and at the same time allows air noise to pass into the sculptured wedge Melamine material. Finally, the outer layer consists of 22 gauge galvanized steel spiral pipe. Please allow 4 to 10 working days for fabrication.
