Compatible Projector Models

This air filter fits Hitachi projectors including the S55i, X55i, LKX62W, X62, X62W and X71C. It replaces original part numbers 78-6969-9861-2 and 78-6969-9875-2. The component is supplied new and weighs 0.2500 units.

Maintenance Timing and Limits

The filter suits owners performing routine upkeep or a lamp change on the listed models. It is not for buyers who need a replacement lamp assembly or a filter for projectors outside the named series. Visual inspection is advised if the unit lacks a warning indicator.

Sustained Cooling Protection

A clean filter maintains airflow to the optical engine during extended operation, preventing heat buildup that shortens component life. When the filter clogs, fan efficiency drops and internal temperatures rise steadily. Replacing it at each lamp interval preserves long-term projector reliability.
