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.
*1 This value is calculated by continuously turning the lamp on for 2 hours and off for 0.25 hours. The lamp replacement cycle will decrease if the lamp is turned on /off more frequently, or if it is left on for longer intervals.
Extreme care has been taken in designing the dust-resistant structure inside the PT-FW430 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*1 of 12,000 hours reduces the hassle of maintenance. And, as an environmental consideration, the filter can be washed with water and reused.*2
*1 The usage environment affects the duration of the filter.
*2 When washing with water, please follow the procedures listed in the operating instructions. Also, we recommend replacing the filter with a new one after it has been washed and reused twice. If the filter is not sufficiently clean after washing, replace it with a new one.
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 PT-FW430 Series projectors’ 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.
