Flexible duct connecting
Flexible duct connectors are essential components in HVAC systems, designed to decouple the rigid sheet metal ductwork from noisy air-handling equipment like fans, blowers, and air conditioners. This isolation prevents the transmission of mechanical vibration and noise into the duct system. These connectors typically feature a flexible, fabric membrane—often made of fire-rated vinyl or neoprene—sandwiched between two strips of galvanized sheet metal. This arrangement creates an airtight seal while maintaining the necessary elastic break between the vibrating equipment and the fixed duct. The strategic use of flexible connectors is critical for acoustic control and system longevity. By absorbing vibration, they protect the ductwork from fatigue and reduce noise levels in occupied spaces, ensuring compliance with sound specifications and contributing significantly to overall occupant comfort.
