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
Ahigh-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.
