Panasonic PT-FW300EA manual High Durability for Long-Lasting Brightness, Dust-Resistant Design

Performance You Can Count On

In addition to being bright and easy to use, the PT-F300 Series 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 polarisers. The new Auto Cleaning Filter (ACF) extends the filter replacement cycle to over 10,000 hours,* 1 and together with the dust-resistant design boost reliability.

Dust-Resistant Design

In developing the dust-resistant design, Panasonic totally re-engi- neered the airflow path, from intake to exhaust, to create a cabinet that hermetically seals off the projector interior. This design and the ACF

team up to keep the air inside the projector clean for long periods of time and minimise any brightness degradation.

The front panel covers the lens to protect from dust, and conceals the controls to pre- vent accidental misoperation. It can be opened for easy access to controls even after the projector is mounted to the ceiling.

Panasonic’s proprietary Auto Cleaning Filter (ACF) uses a highly efficient electrostatic filter called the Micro Cut Filter. The ACF brushes away dust that adheres to the filter, which helps prevent clogging that can impair operation or cause malfunction. This helps maintain the Micro Cut Filter’s superior dust-collecting per- formance and, coupled with a

Micro Cut Filter

A highly efficient electrostatic filter in the air intake section traps dust particles that are 1 micron or larger. By capturing approximately seven times as more dust than conventional filters, it guards the optical block and reduces the penetration of dust into the interior to provide stable operation and halt drops in brightness.

5,000-Hour Lamp Life

Lamps used in a projector require much higher precision than ordinary household lamps. Panasonic employs a number of advanced technologies

—including a proprietary lamp drive system—that help maintain optimal lamp performance for longer-lasting brightness. This has resulted in a 5,000-hour*2lamp replacement cycle.

*1 The replacement cycle given here is a guideline. It may be shorter depending on the usage environment.

*2 This is a maximum value calculated by continuously turning the lamp on for 3.5 hours and off for 0.5 hour. The lamp replacement cycle will decrease if the lamp is turned on/off more fre- quently, or if it is left on for longer intervals.
