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,

High Durability for

Long-Lasting Brightness

New Inorganic Materials Add Durability to

the Optical Block

The F300 Series projectors'

optical block maintains a high

level of performance over

time, due to the use of inor-

ganic materials in the LCD

panels and polarisers. It also

makes them the logical choice

for a truly dependable LCD

projector system.

Auto Cleaning Filter to Minimise Maintenance

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

and together with the dust-resistant design boost reliability.

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.

dust-resistant design, minimises brightness loss

due to dust accumulation. As a result, the filter does

not need to be replaced for over 10,000 hours, *

greatly reducing the hassle of maintenance.

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.

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*

lamp 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.

ACF brush

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.
