Helios Fans DIF 630
Helios
Prices & Options
The Helios DIF 630 is a precision-engineered diffuser optimized for high pressure recovery in ventilation systems. Its aerodynamic shape introduces a size expansion that slows the airflow, converting dynamic pressure into static pressure for improved efficiency. It can also be used as an adapter to transition smoothly to the next duct size.
This diffuser is ideal for placement immediately behind a fan or at the end of a duct system, serving as an outdoor outlet with minimized discharge losses. For free outlet installations, a protective grille (type SG) in the next larger size can be added for safety.
Constructed from hot-dip galvanized steel, the DIF 630 features a high-quality design with a double-sided welded flange and a DIN 24155-compliant hole pattern for compatibility with standard ductwork.
