RCSA, round dissipative SOUND ATTENUATOR (SILENCER), is designed to provide solution to all HVAC discharge noise for round duct.
FEATURED STANDARD CONSTRUCTION
• FRAME:
-Constructed from 20 gauge galvanized frame, formed with lock seams with mastic sealant.
• POD:
- Constructed from 22 gauge galvanized frame.
- 8”(200mm) wide radiused at one end to minimize air pressure loss and regenerated noise.
• INFILL:
- 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 at high-air velocity.
- Clean liner glass fiber as last layer.
• SIZES:
- Minimum Diameter Size:
D = 6”(150mm) without Pod
D = 14”(350mm) with Pod
- Maximum Diameter Size:
D = 60”(1500mm) Diam
(larger size can be manufactured on special order)
- Minimum Length Size:
L = 24” (600mm)
-Round silencers with diameter less than 26” are manufactured using the minimum length size L=24”
-Round silencers with diameter greater or equal to 26” can be manufactured either L = 1D or
L = 2D.
-Round silencers with 26” diameter and above in length L = 2D are manufactured as multiple section and field assembled (by others).
OPTIONS
• 18Ga or 16Ga casing & splitters frame.
• Aluminum Construction
• Standard flange 2” galvanized (50mm), 3mm thickness.
• Pod can be removed for diameter greater than 14”
N.B: - Length of the sound attenuator is: L = 1D or 2D
