Delta-flex Insulated Duct Connector

Delta-flex Insulated Duct Connector is a premium-grade vibration and sound isolation joint designed specifically for HVAC duct applications where both thermal insulation and acoustic damping are required. It is engineered to prevent mechanical vibration and fan noise from transferring into rigid duct systems while also minimizing energy loss and condensation risks.

Manufactured by Delta Duct Air Conditioning L.L.C., UAE, this connector is ideal for advanced HVAC systems in commercial, residential, and industrial environments.

Construction & Design

The Delta-flex Insulated Duct Connector is constructed using:

• Outer Fabric Layer: Fire-resistant, abrasion-proof flexible fabric tested to NFPA 701-2010.
• Insulation Core: High-density fiberglass layer for thermal and acoustic insulation.
• Inner Fabric Layer: Reinforced fire-rated fabric providing secure airflow isolation.
• Side Strips: Precision-formed galvanized steel sheets with lock-seam joining for structural integrity.

This insulated multi-layer structure provides vibration absorption, thermal resistance, and sound attenuation while maintaining flexibility during installation.

Key Features

• Thermally Insulated – Reduces energy loss and prevents condensation at duct transitions.
• Acoustic Vibration Control – Minimizes fan noise and vibration transfer.
• Fire-Rated Fabric – Tested in accordance with NFPA 701-2010.
