Product Overview

The Acoustic Flexible Duct is designed specifically for noise-sensitive ventilation applications requiring sound attenuation, thermal insulation, and flexible installation. Built with a micro-perforated inner aluminum core supported by a steel spring helix, sound waves generated by inline fans and high-velocity airflow pass through the perforations directly into the surrounding acoustic fiberglass insulation. This significantly dampens system decibels while maintaining optimal airflow and temperature control.

Key Performance Characteristics

  • Active Sound Attenuation: Micro-perforated inner core traps sound waves within the acoustic glass wool layer, significantly muffling fan decibels and airflow hum.
  • Flexible Routing & Easy Fitting: Highly pliable construction allows smooth bending around corners without cracking or needing rigid elbow joints.
  • Dual Thermal & Noise Protection: Simultaneously manages indoor room temperatures and suppresses high-CFM ventilation exhaust noise.
  • Air-Tight Vapor Seal: Durable outer aluminum jacket provides an air-tight seal to prevent leakage along extended flexible duct runs.
