Description

The ALU flexible duct connector is manufactured from multi-layer aluminium laminate with reinforced edges for a durable, airtight seal. Designed to decouple HVAC equipment from rigid ductwork, it absorbs axial, lateral, and angular movement caused by fan vibration and thermal expansion. The connector maintains full airflow capacity while dramatically reducing structure-borne noise, making it the ideal choice for comfort-critical applications such as offices, hospitals, and hotels.
