projector

  Access to the lamp from the top of the projector means you can replace the lamp on ceiling-mounted projectors without needing to take down the projector. 
   
   

*1 For projectors under 5 kg as of May 12, 2008.
*2 Guidelines based on 8 hours of use per day (actual filter operating time: approx. 3,000 hours). (Based on accelerated testing in the JIS D-0207 experimental environment.)
*3 Previous model: PLC-XU78/XU75 

 Ingestion of dust into the projector leads to reduced brightness and a deterioration in picture quality.
The PLC-XC55/XC50 features a new dust-resistant design that limits the movement of air through the projector to the intake and exhaust vents. 
     
  A lens cover helps keep dust from finding its way into the projector around the lens, a longstanding problem with conventional designs.
A sliding cover plays the same role for the focus and zoom controls. 
   
  Build-in airflow and air pressure sensors detect intake airflow during operation. When a clogged filter is detected due to airflow falling below a certain threshold, the filter is advanced automatically to replace the dirty surface with a clean one, eliminating the need to clean the filter. The filter cartridge replacement cycle is about one year*2.
The PLC-XC55/XC50's use of a large filter approximately three times as fine as previous models*3 keeps even microscopic dust from entering the projector.
