A large, high-performance electrostatic dust filter that traps fine dust particles ( with an efficiency of 85% for particles as small as 1.6 microns ) comes as standard equipment. In addition to this there is a pre-filter which prolongs the life of the high-performance filter by catching larger particles in advance. An anti-scattering design keeps tiny particles of collected dust from being dispersed back in to the air when replacing the filter, and a timer function conveniently alerts the user when it is time for filter replacement.

Based on precise airflow analysis, internal air is kept clean at all times

A projector needs a constant intake of outside air for internal cooling, and the PD121X design is based on a careful analysis of the airflow from intake to exhaust. Fans are deployed at key points, and the airflow is optimized to enable proper cooling with only one ventilation port, thereby limiting the intake of air that bypasses the filter. By restricting dust intrusion, performance is maximized and the lifespan of the lamp and electronic circuitry is prolonged.

Hermetically sealed DLP® unit

Protects the lens from scratching by dust, etc. This special coating also prevents unwanted reflections.
A clear cover fits tightly over the operation panel, effectively sealing it from dust. This is especially important in a unit used as a ceiling-mounted projector.
A special cover fits tightly over the adjustable portion of the zoom and focus ring.

Designed to minimize deterioration in lamp performance caused by dust and dirt

Keeping the lamp and deflector clean is important for maintaining lamp brightness. The PD121X achieves this via its dust-resistant design, which prevents the influx of airborne particles and thereby minimizes lamp deterioration.
