Product Details

Silicone Flexible Duct Connector with Galvanized Edges is a vital HVAC component designed to connect AHUs, blowers, or air conditioners to ductwork. It effectively isolates machine vibrations and reduces operational noise.

Key Features

  • High Temperature Resistance: Significantly higher heat resistance than standard PVC connectors; ideal for hot air or exhaust systems.
  • Non-Combustible: Fiberglass fabric is flame retardant, providing maximum safety for buildings and factories.
  • Superior Durability: Silicone protects against UV, ozone, and moisture, preventing the fabric from cracking even in outdoor or high-heat environments.
  • Chemical Resistance: Excellent resistance to chemical vapors, oils, and basic acids/alkalis.
  • Vibration Isolation: Isolates vibrations from blowers/AHUs to prevent noise transmission through steel ductwork.

Size: 70 x 100 x 70 mm (Steel x Fabric x Steel)

Silicone Flexible Duct Connector with Galvanized Edges is the ideal choice for industrial HVAC systems exposed to high temperatures. Made from high-quality fiberglass fabric coated with grey silicone on both sides, it is securely bonded to galvanized steel edges to prevent rust and air leakage.

Usage Instructions

  1. Measure: Measure the width and circumference of the duct to determine the required length of the flexible connector.
  2. Cut to Size: Cut the flexible duct connector from the roll (allow 5-10 cm for seam overlap).
  3. Form and Fold: Fold or bend the galvanized edges to match the duct flange shape (round or rectangular).
  4. Install and Secure: Attach the galvanized edges to the machine flange (e.g., AHU) and duct flange using sheet metal screws, rivets, or clips.
  5. Seal Joints: Seal metal joints with silicone sealant or aluminum tape to ensure an airtight finish.
