Description
The verified SALDA RSK variants use a galvanized-steel casing and aluminium blades to restrict reverse airflow in circular ventilation ducts. Their manufacturer article codes and diameters match LETO records. VN-183 is internally named RSK 150, but its manufacturer and article-code match require confirmation; SALDA specifications and the family image are not confirmed for that SKU. Dimensions shown for verified variants come from the current manufacturer selection tool.
