The PT-RQ22K brings unassailable image-quality to body dimensions comparable to Panasonic’s 10,000-lumen-class projectors. Panasonic has eliminated air filters from its 20,000 lumen class, enabling maintenance-free operation for up to 20,000 hours. This is achieved with hermetically sealed optics and unique heat-pipe-based cooling with one-way airflow. The projector can operate continuously for long periods, even in smoky staging conditions.
