Shenzhen ZhenJing technology as air purification industry 10 years enterprise, give their professional advice! First of all, buy back the FFU, installation before the need for the main issues?
One, FFU installation before off requirements:
1, clean work area must be closed.
2, all the ceiling skeleton has been installed and adjusted level.
3, the installation of personnel need to be equipped with uniform clean clothing, to prevent man-made pollution ffu box and high efficiency filter.
Second, the fan unit and high-efficiency filter simple installation steps and precautions:
1, first of all, the fan unit through two or three groups of people were uploaded to the keel above, the process should be noted that in the entrance to tilt out of the entry, in order to prevent damage to the fan unit.
2, the same tilted way to pass the high-efficiency filter to the keel, and make it combined with the keel. Because the filter cartridge inside the filter frame is very fragile and vulnerable. In the process of installing and transferring, you can only hold its frame tightly and put it down gently, not touching the filter element inside, and resolutely avoiding collision with the filter element. In the process of combining with the keel, pay attention to the direction of the air outlet side of the high-efficiency filter should be facing down.
3, followed by the installation of the fan unit and HEPA, the fan unit is placed close to the hepa, the installation should be careful, in order to prevent damage to the HEPA. installed, you must check whether their combination is uniform, tight.
Three, FFU maintenance notes
Doing a good job of ffu maintenance can effectively improve the life of ffu fan filter unit, the enterprise to save a certain amount of money. Related maintenance notes are organized as follows:
1, according to the cleanliness of the environment, ffu fan filter unit replacement filter (primary effect is generally 1-6 months, high efficiency is generally 6-12 months, high efficiency filters can not be cleaned.)
2, regularly (generally once every two months) with the dust particle counter to determine the cleanliness of the clean area with the implementation of the product purification, when the measured cleanliness does not match the required clean, the reasons should be identified (whether there is a leakage, high-efficiency filters are effective, etc.), if the high-efficiency filters have been effective, should be replaced with a new high-efficiency filters.
3, the replacement of high-efficiency filters and primary filters should pay attention to the implementation of the following:
① ffu fan filter unit replacement of high-efficiency filters should pay special attention to the unboxing, handling and installation to ensure that the filter paper is intact, and prohibit the use of hands to touch the filter paper to cause damage.
② ffu installation, the heart of the high-efficiency filter to the bright spot, to the naked eye to observe whether the high-efficiency filter due to transportation and other reasons for damage, such as holes in the filter paper can not be used.
③ ffu replacement of high-efficiency filters should first lift the box, and then take out the failed high-efficiency filters and replace them with new high-efficiency filters
