TAPERED DISSIPATIVE
In 1966, Charlie Rink first developed a family of silencers with superior Dynamic Insertion Loss and Static Pressure characteristics. Today, that family of silencers consists of the Ruskin Sound Control Models A, AM, and DM. These silencers are the first choice of designers for rectangular dissipative silencers. As with all Ruskin Sound Control silencers, the data for these products has been developed in strict accord with ASTM E477 in independent, nationally recognized laboratories.
Primary Applications
- Standard: VAV boxes, rectangular ductwork, air handling units, generator radiator silencing, tunnel ventilation, general ventilation.
- W/ Non-fibrous Liner: Cleanroom systems, hospitals, chemical laboratories, cooling towers (DM), fume hood exhaust.
