Flexible Duct Connector

Flexible Duct Connector – Vibration & Noise Isolation for Ducting Systems

Durable, Airtight Solution for Fans, AHUs & Duct Installations

The Flexible Duct Connector is a high-performance joint designed to eliminate noise and vibration transmission between fans, air handling units, and ductwork. It consists of a durable PVC fabric layer bonded between two strips of galvanised steel, providing both flexibility and structural integrity.

Engineered for use in commercial and industrial ventilation systems, this connector improves system longevity, reduces acoustic transmission, and ensures a secure, airtight seal—compliant with EN 1507:2007 Class D airtightness standards.

✅ Key Features:

• Vibration & Noise Isolation
  Prevents transmission of mechanical vibrations and noise into the duct system.

• Durable Construction
  Made from galvanised sheet metal with a high-quality PVC centre fabric layer.

• Airtight Performance
  Compliant with Class D (EN 1507:2007) airtightness standards, tested at 2000 Pa.
