The Most Invincible Classroom Projector that Guarantees World-Class Learning Quality
Time to dustproof your projectors at school
● Sandy playgrounds and the habit of opening classroom windows are increasing the concentration of harmful dusts in indoor environments. 
● Several kinds of pollutants (from PM 10 to PM 2.5) that fill the air can damage your classroom projectors.
Education projector’s performance would be compromised by:

1. Dust accumulation on internal parts, which will cause image blemish, thermal issue, signal detection failure, brightness and color decay.

Unlike DLP projector's sealed design, non-DLP projector's open optical engine design has a higher chance of exposing internal parts to dust accumulation, which can affect projection quality.

2. Dust accumulation on color wheel sensor, which will cause flickering, abnormal color and shutdown.
