7ZL PPG -- Multi-Wing Fan Blade
Wide-chord left-hand rotation blade in polypropylene. The 7Z has the widest chord in the Z-range at 23cm — used in high-pressure forced-draft systems, dust extraction with heavy filter loading, and long duct installations requiring significant pressure rise.
Polypropylene Glass-Filled (PPG)
PPG blades offer superior chemical resistance compared to standard PAG. Ideal for applications where blades are exposed to corrosive gases, chemical fumes, aggressive cooling water treatment, or acidic environments.
