自净器（Automatic Purifier）

自净器是一种可移动的空气净化设备，可放置在室内、乱流洁净室的四角、涡流区，以减少灰尘滞留的机会，形成洁净室的空气环境，也可作为操作点临时净化措施，用以满足精密仪表、电子工业、卫生、食品及科研部门的需要。同时在自净器出风口前方，能得到高洁净度的局部环境，可与有关设备配套使用。

Automatic Purifier is a mobile air purifying equipment which can be placed indoors or at four corners of the Disorder Flow Clean Room and whirlpool area in order to reduce the possibility of dusts existing and maintain a clean air environment. It also can be used as temporary purifying equipment at the operation site of precise instrument, electron industrial, sanitation, food and scientific research departments. Additional, the Automatic Purifier can work together with other equipments to provide a partial high cleanliness grade environment.

工作原理：

自净器由预过滤器、通风机、负压箱、正压箱、高效过滤器等部件组成。工作过程是：当通风机运转后吸入室内空气，通过初步除尘压入静压箱，再经高效过滤器进一步净化并以水平平行流状态流向箱体前方，从而室内空气通过自净器往复循环达到洁净的工作环境。

使用范围： 自净器适合于10000～100000级较低洁净环境的场合，也可用于局部净化级别较高的环境。
