Panasonic PT-F200EA - Manual (Page 2)

With their outstanding flexibility,
PT-F200 series projectors make
ideal replacements for existing
ceiling-mounted systems. They
require little maintenance after
installation, so total cost of
ownership is low.

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 projector automatically
detects when dust accumulates on the high-efficiency electro-
static filter and impairs performance. The affected section of the
filter is wound into the casing, so the filter maintains its dust-
catching capability. 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 pro-
jector 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.
