Maintenance and upkeep of FFU fan filtration unit in clean room

Proper maintenance and upkeep of the FFU fan filtration unit in the clean room can improve its lifespan and save businesses some costs.
1、 According to the cleanliness of the environment, the FFU fan filter unit needs to replace the filter (the initial efficiency is generally 1-6 months, the high efficiency is generally 1-2 years, and the high efficiency filter cannot be cleaned).

2、 Regularly (usually every two months) use a dust particle counter to measure the cleanliness of the clean area where this product is used for purification. When the measured cleanliness does not meet the required cleanliness, the cause should be identified (whether there is a leak, whether the high-efficiency filter has failed, etc.). If the high-efficiency filter has failed, a new high-efficiency filter should be replaced.
3、 When replacing high-efficiency filters and primary filters, the machine should be stopped.
4、 When replacing the high-efficiency filter of the FFU fan filtration unit in the clean room, the following precautions should be taken:
1. When replacing the high-efficiency filter of the FFU machine filter unit, special attention should be paid to unpacking, handling, and installation to ensure that the filter paper is intact and undamaged. It is forbidden to touch the filter paper with hands to cause damage.
2. Before installing FFU, place the new high-efficiency filter against the bright spot and visually observe whether the high-efficiency filter has been damaged due to transportation or other reasons. If the filter paper has a leak, it cannot be used.
3. When replacing the high-efficiency filter of FFU, the box should be lifted first, and then the failed high-efficiency filter should be removed and replaced 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 from the purification unit). After ensuring that the frame is sealed, the box cover should be returned to its original position.
