華宇凈化談談FFU風機過濾單元的維護保養

             對FFU風機過濾單元進行適當的維護保養可以提高FFU風機過濾單元的壽命，對企業節省一定的費用。

               一、根據環境的潔凈度，FFU風機過濾單元更換過濾器（初效一般為1-6個月，一般為6-12個月,過濾器不可清洗）。

                   二、定期（一般每兩個月一次）用塵埃粒子計數器測定用本產品實施凈化的潔凈區域的潔凈度，當實測的潔凈度與要求的潔凈度不符時，應查明原因（是否有泄漏、過濾器是否有失效等），若過濾器已失效，則應更換新的過濾器。

                三、更換過濾器及初效過濾器時應停機進行。

               四、FFU風機過濾單元更換過濾器時應注意以下事項：

1、FFU機過濾單元更換過濾器時應特別注意拆箱、搬運及安裝取用時確保濾紙完整無損，禁止用手觸及濾紙造成破損。

2、FFU安裝前，將新的過濾器對著亮處，以肉眼觀察過濾器是否因運輸等原因而出現破損，如濾紙有漏洞則不能使用。

3、FFU更換過濾器時應首先將箱體抬起，然后將失效的過濾器取出，換上新的過濾器（注意過濾器的氣流箭頭標志應與凈化單元出風氣流方向一致），確保邊框密封后將箱蓋回原位。

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.
