Exact-Fit Replacement Filter

The Maxell 78-8118-9641-0 air filter is manufactured for Hitachi S55i, X55i, X62, X62W, X71C and LKX62W projectors. It matches the original part number 78-6969-9861-2 and 78-6969-9875-2 for direct compatibility. Facility managers and home-theatre owners use it to maintain proper airflow through the optical engine. A clogged filter reduces cooling efficiency and shortens the lamp life.

Scheduled Maintenance Upgrade

This filter replaces the factory unit during routine service or when a filter-warning icon appears on screen. Manufacturers recommend cleaning every three months and swapping the filter at each lamp change. The swap is straightforward and requires no tools. Installers who skip this step risk dust buildup on colour wheels and polarisers.

Sustained Thermal Protection

Under continuous operation the filter traps airborne particles before they reach the heatsink and fan assembly. A clean element keeps internal temperatures stable during long presentations or movie marathons. When the media loads with dust the fan speed rises and hot spots form near the lamp housing. Regular replacement preserves the projector’s thermal design limits.
