Compatible Hitachi Projector Models

The NJ22211 air filter fits Hitachi S55i, X55i, LKX62W, X62, X62W and X71C projectors. It replaces OEM part numbers 78-6969-9861-2 and 78-6969-9875-2. This component is intended for owners of those specific models who need to maintain internal airflow and protect optical surfaces from dust accumulation.

Installation and Maintenance Context

The filter sits inside the projector chassis and intercepts airborne particles before they reach the lamp and lens assembly. Replacement is straightforward and often performed during routine lamp changes. Regular swaps prevent clogging that would restrict cooling airflow and raise internal temperatures, which shortens component life.

Sustained Operation Benefits

A clean filter allows the cooling system to maintain stable temperatures over long projection sessions. When the filter is neglected, dust buildup reduces fan efficiency and causes gradual heat accumulation that degrades the lamp and optical engine. Changing the filter at each lamp interval preserves consistent thermal performance throughout the projector's service life.

Questions about this item

When should I replace the NJ22211 air filter to avoid heat buildup?

Replace the filter when changing the lamp or whenever a filter warning icon appears on screen, as a clogged filter reduces cooling fan effectiveness and causes internal heat buildup.

How loud does the projector get if the NJ22211 filter is clogged during all-day use?

A clogged filter forces the cooling fan to work harder, increasing noise and reducing its effectiveness, which leads to internal heat buildup that shortens projector and lamp life.

Which Hitachi projector models is the NJ22211 filter compatible with?

The NJ22211 filter fits Hitachi S55i, X55i, LKX62W, X62, X62W and X71C projectors, replacing part numbers 78-6969-9861-2 and 78-6969-9875-2.
