Clean roomFFUAlso known as cleanroom specific FFUGuangzhou Zijing FFU manufacturer, specializing in clean room FFU/purification workshop FFU, with a hundred level clean room FFU and air purification equipment,laminar hoodCleanroom FFU installation and FFU can be customized according to customers' actual requirements for non-standard cleanroom FFUs, such as cleanrooms.
Fan Filter Units, abbreviated as FFUs. It is a self powered end air supply device with filtering function; The FFU fan sucks in air from the top and filters it through HEPA, then evenly sends out clean air from the outlet surface; This product is a 1175X575X255 inner rotor motor+410 plastic impeller. The product size and accessories can be customized according to customer requirements.
As a high clean air purification equipment, cleanroom FFUs are widely used in Class 10, Class 100 cleanrooms, and cleanroomsCLEAN BOOTH、Clean workbenchApplication scenarios such as clean production lines, modular clean rooms, and local level 100 cleanrooms.

Cleanroom FFU classification:
Ordinary type, energy-saving type, group control type

Clean roomFFUConfiguration and composition:
1. The box body can be made of materials such as stainless steel, aluminum zinc plated plate, cold-rolled steel plate, electrostatic spraying, etc. It is lightweight, corrosion-resistant, rust proof, and aesthetically pleasing.
2. The fan adopts a direct drive high-efficiency centrifugal fan, which has the characteristics of long life, low noise, maintenance free, low vibration, and stepless speed regulation. The quality of the fan is reliable, and the working life is up to 50000 hours or more.
3. HEPA high efficiency ranging from 99.99% @ 0.3um to 99.999% @ 0.12um, with excellent air uniformity distribution performance.
4. It has the characteristics of energy saving, centralized computer control, stable operation, and digital speed regulation. A computer can be used to centrally control the operation, speed regulation, and work status query of 8000 wind turbines.
5. The products are scanned and tested by a dust particle counter before leaving the factory to ensure quality.

1、 Requirements for pre installation of cleanroom specific FFU:
1. The clean work area must be sealed.
2. All ceiling frames have been installed and leveled.
3. Installation personnel should be equipped with uniform clean clothing to prevent human contamination of the cabinet and high-efficiency filter.

2、 Simple installation steps and precautions for clean room FFU fan unit and high-efficiency filter:
1. Firstly, the fan unit is uploaded onto the keel by two or three groups of personnel. During this process, attention should be paid to tilting the entrance and exit to prevent damage to the fan unit.
2. Transfer the high-efficiency filter to the keel in the same inclined manner and combine it with the keel. Due to the fragility and vulnerability of the filter element inside the filter frame. During the installation and transmission process, only grip its frame tightly, handle it gently, and do not touch its internal filter element to avoid collision with the filter element. During the process of combining with the keel, it is important to note that the direction of the high-efficiency filter's air outlet should face downwards.
3. Next is the installation of the fan unit and HEPA. Place the fan unit tightly against the HEPA and be careful during installation to prevent damage to the HEPA. After installation, it is necessary to check whether their bonding is uniform and tight.3、 Precautions for Clean Room FFU Maintenance and Repair
Doing a good job in repairing and maintaining the FFU can effectively improve the service life of the FFU fan filter unit and save some costs for the enterprise. The relevant maintenance precautions are summarized as follows:
1. According to the cleanliness of the environment, the filter of the FFU fan filtration unit should be replaced (the initial efficiency is generally 1-6 months, the high efficiency is generally 6-12 months, 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 is effective, etc.). If the high-efficiency filter is effective, a new high-efficiency filter should be replaced.
3. When replacing high-efficiency filters and primary filters, the following measures should be taken:
① When replacing the high-efficiency filter of the FFU fan 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, point the high-efficiency filter of the heart towards the bright spot and observe with the naked eye whether the high-efficiency filter has been damaged due to transportation or other reasons. If there are leaks in the filter paper, it cannot be used.
③ When replacing the high-efficiency filter, the housing should be lifted first, and then the failed high-efficiency filter should be removed and replaced with a new one.
