What should we pay attention to in the maintenance of the fan filter unit?

Proper maintenance of the FFU fan filter unit can not only enhance its work efficiency, but also improve the service life of the FFU fan filter unit. So what should we pay attention to in the maintenance of the fan filter unit?

1. Replace the filter in time according to the cleanliness of the environment, and replace the filter in the FFU fan filter unit

1. First check the color of the upper and lower filter materials of the air filter. If the color of the filter material turns black, it means that it should be replaced in time;

2. Gently touch the filter material on the air outlet side of the air filter with your hand, if you feel the dust is thick, you need to replace it;

3. Regularly record the replacement status and events of the air filter, and summarize the best replacement cycle;

4. When the air filter does not reach the final resistance, and the pressure difference in the room has dropped significantly, it is possible that the resistance of the filter is too large and needs to be replaced in time.

Second, the FFU fan filter unit should pay attention to the following matters when replacing the high-efficiency filter:

1. When replacing the high-efficiency filter in the filter unit of the FFU machine, special attention should be paid to ensure that the filter paper is intact when unpacking, transporting, and installing and taking it. It is forbidden to touch the filter paper by hand to avoid damage.

2. Before installing the FFU, point the new high-efficiency filter to the bright place, and visually observe whether the high-efficiency filter is damaged due to transportation and other reasons. If the filter paper has holes, it cannot be used.

3. When replacing the high-efficiency filter, the FFU should first lift the box, then take out the failed high-efficiency filter and replace it with a new high-efficiency filter (note that the airflow arrow mark of the high-efficiency filter should be consistent with the direction of the air flow out of the purification unit. ), make sure the frame is sealed and put the lid back in place.
