2C81480G01 is a precision aerospace component, compliant with AS9100D quality standards and FAA/EASA regulations, designed for the environmental control systems (ECS) of large commercial aircraft.

It serves as an ECS cabin air filter seal frame, forming a tight, airtight seal between the cabin air filter and the filter housing. This seal ensures that all cabin supply air passes through the filter, blocking particulate contaminants, allergens, and engine exhaust residues from entering the cabin, avoiding poor air quality that would affect passenger comfort, or cause irritation to crew and passengers' respiratory systems during long-haul flights.

Made from lightweight, rigid polycarbonate and flexible EPDM rubber, it operates stably at -50°C to 180°C, and resists abrasion and aging. Weighing 0.12kg, it allows fast MRO replacement, a critical component for cabin air quality and ECS efficiency.
