Delta-flex Uninsulated Duct Connector

Delta-flex Uninsulated Duct Connector is a high-performance flexible joint system designed to isolate vibration, noise, and mechanical stress between air handling units and ductwork. Manufactured by Delta Duct Air Conditioning L.L.C., UAE, this connector ensures quiet and stable HVAC operation by preventing vibration transfer from fans or blowers into rigid duct systems.

Construction & Design

Delta-flex Uninsulated Duct Connector consists of a layer of flexible fire-rated fabric securely bonded between two strips of galvanized steel sheet metal, lock-formed together to create a continuous, durable connector.

• Fabric Layer: Flame-retardant, high-strength cloth tested in accordance with NFPA 701-2010.
• Metal Side Strips: Precision roll-formed galvanized steel for corrosion resistance.
• Lock-Seam Construction: Ensures airtight joints and long-term durability.

This design absorbs vibration, accommodates thermal/structural movement, and dampens acoustic disturbances—enhancing system longevity and reducing structure-borne noise.

Key Features

• Prevents Vibration Transmission from AHUs and fans to duct systems.
• Noise Reduction Capability via flexible fabric isolation layer.
• High Durability with reinforced fabric bonded to galvanized steel.
• Fire-Rated Fabric tested to NFPA 701-2010 flame propagation standards.
