Prices & Options
The Helios Fans RSK 355 is an automatic backdraught flap designed for insertion directly into duct runs. It automatically prevents reverse airflow by operating under both underpressure and overpressure modes using a reliable spring lock.
The housing is made of galvanized sheet steel, providing durability and corrosion resistance, while the flaps are crafted from aluminum with a stainless steel return spring for longevity. For horizontal airflow installations, the axis of rotation should be positioned vertically. In vertical installations, the flap functions correctly only with ascending airflow.
This product is ideal for ventilation systems requiring protection against backflow, ensuring proper airflow direction and enhanced system efficiency.
