PJ559D面向商务和教育市场,使用了优派的“防尘墙”技术,除了对光机进行防尘外,还对灯泡等部件有效防尘。其工控机机体设计的风扇增压技术,可以保证机器内部气压大于外界,从而阻止灰尘进入机身内,再加上全密封的金属光机设计、可反复清洗的立体静电滤网实现全面防尘。更好的防尘性能使得PJ559D在会议室和教室等开放式场所,能够获得更加长久的使用时间。
PJ559D for the business and education markets, the use of ViewSonic “dust wall ” technology, in addition to the light machine dust, but also the light bulbs and other components effectively dust. The IPC engine body design of the fan booster technology, you can ensure that the pressure inside the machine is greater than the outside world, thus preventing dust from entering the fuselage, coupled with a fully sealed metal light machine design, can be repeatedly cleaned three-dimensional electrostatic filter to achieve full dust . Better dust-proof performance makes the PJ559D longer in use in open spaces such as meeting rooms and classrooms.
