CSA-M, dissipative SOUND ATTENUATOR (SILENCER), is designed to provide solutions to all HVAC discharge noise with medium dynamic insertion loss.
FEATURED STANDARD CONSTRUCTION
• FRAME:
-Constructed from 20 gauge galvanized frame, formed with lock seams with mastic sealant.
• SPLITTERS:
- Constructed from 22 gauge galvanized frame.
- 8”(200mm) wide radiused at one end to minimize air pressure loss and regenerated noise.
- Filled with acoustic fibers complying with various standards requirements.
The infill is compressed and contained behind a 22 gauge, 4mm hole diameter perforated metal sheet. This protection prevents damage and fiber erosion up to 5900fpm (30m/s).
- Clean liner glass fiber as last layer.
• AIR WIDTH:
- Varies between 3”(75mm), 4”(100mm), 6”(150mm) & 8”(200mm) depending on required insertion loss and pressure drops.
• SIZES:
- Minimum size of 11”(275mm)W x 8”(200mm)H
- Rectangular silencers with weight that exceed 200Kg (441Lbs) are manufactured as multiple section and field assembled (By others).
