In addition to being bright and easy to use, the PT-FW300U LCD projectors give you enhanced performance with minimal maintenance over time. Highly reliable optical block and a long operating life are ensured by the use of inorganic materials for the LCD panels and polarizers. The Auto Cleaning Filter (ACF) extends the filter replacement cycle to over 10,000 hours, and together with the dust-resistant design boost reliability. It is an ideal replacement in existing systems. The 2x zoom lens and horizontal/vertical lens shift expand the applicable installation area, so you can place them in the same exact locations as your previous projectors. Abundant interfaces minimize additional cabling when replacing projectors. Using serial input and the emulate function, you can continue to use the control commands of previous Panasonic models.
