With their outstanding flexibility,
PT-F100 series projectors make
ideal replacements for existing
ceiling-mounted systems. They
require little maintenance after
installation, so total cost of
ownership is low.

Advanced Technologies that Maintain High
Brightness Over a Longer Service Life
Auto Rolling Filter (ARF) and Anti-Dust Design
A Micro Cut Filter, a high-efficiency electro-
static filter, with superior dust-collecting per-
formance combines with Panasonic’s original
Auto Rolling Filter and anti-dust design to minimise brightness
loss due to dust accumulation. The Auto Rolling Filter periodi-
cally winds the used section into the casing so that a fresh
section of filter is exposed. Thus, peak performance is main-
tained. In developing the anti-dust design, Panasonic totally re-
engineered the airflow path, from intake to exhaust, to create a
cabinet that hermetically seals off the projector interior. This
design and the Auto Rolling Filter team up to keep the air
inside the projector dust-free at all times.

Micro Cut Filter
A high-efficiency electrostatic filter in the air intake section
traps dust particles that are 1 microns* or larger. By cap-
turing approximately 7 times as much dust as our previous
filters, it guards against optical blocks and reduces the
penetration of dust into the interior to provide stable oper-
ation by preventing drops in brightness.
