Product Description

Product Description

Product Description:

Duct silencer kit is a complete noise control solution for HVAC air distribution systems, designed to reduce fan noise, airflow turbulence, and cross-talk between rooms. The kit includes a rectangular or circular silencer body, connecting flanges, acoustic infill material, and mounting hardware. The outer casing is made of galvanized steel or stainless steel, while the internal sound-absorbing core uses fire-resistant mineral wool or glass fiber wrapped in perforated metal sheets. This structure effectively attenuates mid-to-high frequency noise without significantly restricting airflow. The silencer is installed inline with supply, return, or exhaust ducts and is widely used in office buildings, hotels, hospitals, schools, recording studios, and industrial facilities where acoustic comfort is required.

Main Features & Selling Points:

(1) Effective noise reduction: acoustic core absorbs fan and airflow noise, lowering duct-borne sound levels by up to 15-25 dB depending on model.

(2) Fire-safe materials: mineral wool or glass fiber infill meets basic fire resistance requirements, enhancing system safety.

(3) Low pressure drop: optimized internal profile maintains smooth airflow, reducing energy consumption of the HVAC fan.

(4) Durable casing: galvanized or stainless steel shell resists corrosion, moisture, and mechanical damage in long-term service.

(5) Modular installation: flanged ends connect directly to standard ductwork, allowing quick retrofit or new system assembly.

(6) Custom OEM service: available in various lengths, cross-sections, and acoustic performance grades for project-specific needs.
