Delta Duct FD5 – Acoustic Insulated Flexible Duct

The Delta Duct FD5 is a high-performance acoustic insulated flexible duct designed to deliver superior noise attenuation, thermal insulation, and airflow efficiency in air conditioning and ventilation systems. Developed for demanding commercial, industrial, and residential HVAC applications, the FD5 provides quiet, efficient, and durable air distribution where comfort and performance are essential.

Construction & Design

The FD5 combines advanced materials and engineering to ensure excellent thermal and acoustic control:

• Inner Core: Constructed from perforated aluminum/polyester laminate, bonded to a high-tensile steel wire helix, providing flexibility and sound absorption.
• Insulation Layer: Premium glass wool insulation (16, 24, or 32 kg/m³) delivers outstanding thermal and acoustic performance.
• Outer Jacket: Durable metalized polyester with a clear protective coating ensures resistance to tearing, moisture, and corrosion.

Key Features

• Acoustic Performance – Perforated inner core design reduces system noise and vibration transmission.
• Excellent Thermal Efficiency – High-density fiberglass insulation minimizes heat loss or gain.
• Highly Flexible & Lightweight – Easy to install in tight spaces or complex duct layouts.
• Fire-Resistant Construction – Manufactured using flame-retardant materials for added safety.
• Corrosion & Moisture Resistant – Outer jacket ensures long service life even in humid conditions.
• Smooth Internal Airflow – Reduces pressure drop and enhances HVAC system performance.
• Mold & Microbe Resistant – Ensures clean and hygienic air distribution.
