DB BOX - Acoustic Silencer

The DB BOX Acoustic Silencer is a high-performance soundproofing solution designed for situations where standard inline silencers cannot be installed. Engineered for industrial and HVAC applications, the unit combines robust sound insulation with advanced sound absorption to minimise noise from air handling, cooling, and mechanical systems.

How It Works

The silencer operates through a modular structure made of galvanised steel panels and internal sound-absorbing louvres. Each louvre features a perforated metal surface filled with dense acoustic material, allowing air to pass while effectively reducing sound energy across a wide frequency range. This hybrid approach ensures both low-frequency attenuation and broadband noise reduction, improving comfort and compliance in demanding environments.

Key Benefits

• Efficient noise reduction for HVAC systems, compressors, and air ducts
• Combines sound insulation and absorption for optimal performance
• Durable galvanised steel construction with powder-coated finish
• Compact, modular design ideal for restricted or retrofit installations
• Custom dimensions available to suit specific system layouts
• Low maintenance and long operational life

Installation Overview

The DB BOX silencer is designed for flexible integration into existing ductwork, mechanical systems, or industrial enclosures. It can be mounted horizontally or vertically, depending on airflow direction and space constraints. Standard models include configurations with two to five sound-absorbing baffles, while custom units can be tailored to the acoustic requirements and spatial limitations of each project.
