Solutions for Everyone
Most projector problems are caused by dust. A dust-clogged filter reduces the cooling effect, and dust that accumulates inside the projector can lower both image quality and brightness. Ceiling-mounted projectors are often less frequently maintained because they're not easily accessible for cleaning. In fact, it's hard work just to carry a ladder around to all of the projector sites in a large building to carry out maintenance for ceiling-mounted projectors. Also, maintenance can be done only during certain time slots between lectures or after the building closes. This makes maintenance even more laborious.

Filter cleaning is essential for stable projector operation. The F300 Series and D6000 Series with the Auto Cleaning Filter does not require filter cleaning or replacement for about 10,000 hours. The models equipped with the Auto Cleaning Robot (PT-DZ12000/D12000/DW10000/D10000) do not require filter cleaning or replacement for about 2,000 hours.
All models feature a Micro-cut filter that prevents the entry of any lint and particles larger than pollen. And the optical block is completely sealed. In addition, the projectors are designed for dust resistance, enabling Panasonic projectors to maintain their initial performance for a very long time.
The ACF (Auto Cleaning Filter) automatically winds the filter and cleans its surface when the clog sensor detects dust and at preset time intervals.
The ACR (Auto Cleaning Robot) removes dust from the air filter using a brush every time the projector is turned on.
The optical block, the heart of the projector, is completely sealed.
