Panasonic  PT-FX400 Projector

An original lamp drive system and a more durable new lamp unit help maintain optimal lamp performance for longer-lasting brightness than predecessor models.*² This has resulted in a 6,000-hour lamp replacement cycle.

Dust Resistant Design

Extreme care has been taken in designing the dust-resistant structure inside the PT-FX400 Series cabinet. The lens section, where dust enters, has been protected and separated from the optical block, which is the heart of the projector. Integrated molding of internal cabinet parts has also been increased to further improve sealing performance. The intake and exhaust airflow paths are straight, and the intake airflow path is provided with a new Eco Filter unit to guard the optical components from dust.
This dust-resistant design keeps the air inside the projector clean for long periods of time and minimizes brightness degradation. The Eco Filter’s long replacement cycle of 12,000 hours reduces the hassle of maintenance. And, as an environmental consideration, the filter can be washed with water and reused.

The Eco Filter consists of two Micro Cut Filters (electrostatic filters), a pre-filter and a main filter, which use an ion effect to collect extremely small dust particles. The pre-filter has a honeycomb configuration and the main filter is pleated to achieve a large surface area that raises its dust collecting performance. Thanks to these features, the Eco Filter has a replacement cycle of 12,000 hours.

The PTFX400 projector optical block maintains a high level of performance over time, due to the use of inorganic materials in the LCD panels and polarizers, thus achieving a replacement cycle of 12,000 hours. It also makes them the logical choice for a truly dependable LCD projector system.
