The Helios STS 355 is a flexible connector designed to be installed between fans and duct systems to prevent structure-borne noise and absorb installation tolerances. It features an elastic cuff made from durable, silicone-free PVC fabric capable of withstanding temperatures up to 80 °C.
Both ends are fitted with angular flange rings made of galvanised sheet steel, ensuring a robust and secure fit. The hole configuration conforms to DIN 24155 standards, making it suitable for integration into standard ventilation systems.
This connector is ideal for HVAC applications where sound dampening and flexible alignment are essential
