Helios Fans DIF 355
Helios
Prices & Options
The Helios DIF 355 diffuser is aerodynamically optimized to enhance pressure recovery by slowing airflow through a size transition, converting dynamic pressure into static pressure. It also serves as an adapter to ensure an efficient transition to a larger duct diameter.
Designed specifically for installation immediately after a fan or at the end of a duct system, the DIF 355 minimizes outlet losses when used as an external discharge point. When operating as a free outlet, it can be paired with a protective grille (type SG) in the next larger size for added safety.
Constructed from durable hot-dip galvanized steel, the diffuser includes a double-sided welded flange and features a hole pattern in accordance with DIN 24155 specifications.
