The Helios DIF 280 is a high-performance diffuser engineered for enhanced pressure recovery through aerodynamic optimization. It reduces air velocity by creating a size transition, effectively converting dynamic pressure into static pressure. This component also serves as an adapter for seamless transitions to larger duct sizes.
Ideal for placement immediately after a fan or at the termination of a duct system, the DIF 280 helps minimize outlet losses when used as an external discharge point. When installed with a free outlet, a protective grille (type SG) in the next larger size can be added for safety.
Constructed from hot-dip galvanized steel sheet, the diffuser features a robust design with a double-sided welded flange and a hole pattern that complies with DIN 24155 standards.
