FFU风机过滤单元的维护保养

2019-05-06

FFU风机过滤单元进行适当的维护保养可以提高FFU风机过滤单元的寿命,对企业节省一定的费用。

一、根据环境的洁净度,FFU风机过滤单元更换过滤器(初效一般为1-6个月,高效一般为6-12个月,高效过滤器不可清洗)。

二、定期(一般每两个月一次)用尘埃粒子计数器测定用本产品实施净化的洁净区域的洁净度,当实测的洁净度与要求的洁净度不符时,应查明原因(是否有泄漏、高效过滤器是否有失效等),若高效过滤器已失效,则应更换新的高效过滤器。

三、更换高效过滤器及初效过滤器时应停机进行。

四、FFU风机过滤单元更换高效过滤器时应注意以下事项:

1FFU机过滤单元更换高效过滤器时应特别注意拆箱、搬运及安装取用时确保滤纸完整无损,禁止用手触及滤纸造成破损。

2FFU安装前,将新的高效过滤器对着亮处,以肉眼观察高效过滤器是否因运输等原因而出现破损,如滤纸有漏洞则不能使用。

3FFU更换高效过滤器时应首先将箱体抬起,然后将失效的高效过滤器取出,换上新的高效过滤器(注意高效过滤器的气流箭头标志应与净化单元出风气流方向一致),确保边框密封后将箱盖回原位。

The proper maintenance of the FFU fan filter unit can improve the life of the FFU fan filter unit and save the enterprise a certain cost.

1. According to the cleanliness of the environment, the FFU fan filter unit changes the filter (the initial effect is usually 1-6 months, the efficiency is generally 6-12 months, and the efficient filter is not to be cleaned).

2. On a regular basis (usually once every two months) with dust particle counter measure with this product purification clean area cleanliness, when measured cleanliness does not accord with requirement of cleanliness, should find out the reason (if there is leakage, high efficiency filter, etc.) if there is a failure, if efficient filter has failed, it should be replaced a new hepa filter.

3. When replacing the high efficiency filter and the initial filter, the machine should be stopped.

4. FFU fan filter unit should pay attention to the following items when replacing the efficient filter:

(1)The FFU filter unit should pay special attention to the removal, handling and installation of the filter when replacing the efficient filter. The filter paper is intact and the paper is prohibited to touch the filter paper to cause damage.

(2)Before the FFU is installed, the new high efficiency filter will be applied to the light to see whether the high efficiency filter can be damaged due to transportation and other reasons. If the filter paper has a loophole, it cannot be used.

(3)Head to replace hepa filter should be the first to raise box body, and then the failure of high efficiency filter, change into a new high efficiency filter (note that the flow arrow symbol of hepa filter shall be the purification unit of blast in the same direction), to ensure that the border will cover back in place after the seal.
