Donaldson to provide cabin air filters for new Boeing
Donaldson has been selected by Boeing to provide the HEPA cabin recirculation filter and electronic equipment (E/E) cooling filter for the new Boeing 747-8 Freighter and Intercontinental aircraft.
Donaldson will design, develop, and qualify the HEPA cabin recirculation filter and the E/E cooling filter. When installed, the new HEPA cabin air circulation filter will reportedly provides higher efficiency and an extended filter life due to its media design. Donaldson HEPA filters meet or exceed 99.97% efficiency on 0.3µm, the highest rating available for aircraft cabin recirculation systems, trapping dust, lint, smoke, bacteria, viruses, spores and other contaminants. The new E/E cooling filter will protect the avionics equipment from contamination, which can cause higher operating temperatures and can lead to equipment malfunction or failure.
