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 polarizers. It also
makes them the logical choice
for a truly dependable LCD
projector system.
Auto Cleaning Filter to Minimize 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
dust-resistant design, minimizes 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 minimize 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.
Performance You Can Count On
1
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
polarizers. The new Auto Cleaning Filter (ACF) extends the filter replacement cycle to over
10,000 hours,

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.

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.
*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.
