Abstract

An art, method and process of protecting fan/propeller blades, mainly the leading edge, from pitting as a result of corrosion and foreign object damage including dust particles. An art, method and manner of preventing humidity-led pitting of fan/propeller blades that operates on high velocity domestic fans, centrifugal fans, and rotarials and ensures safe operation. A protective composition that yields to a plastic based shields that slide into the sharp edge of fans, mainly the leading edge and partly surrounds it and obstructs humidity access to it.
