FFU comes with a high-efficiency filterProduct Description:

What is FFU high-efficiency filter? The FFU high-efficiency filter is a high-efficiency filter installed on the FFU fan, generally made in the form of no partition high-efficiency filter. The filter material is made of ultra-fine glass fiber, with a filtration grade of 99.99%, mainly capturing 0.3um dust particles.
FFU high-efficiency filters are widely used in manufacturers of semiconductors, electronics, flat panel displays, disk drives, optics, biotechnology, clean production lines, clean workbenches, clean rooms, modular clean rooms, laminar flow hoods, and other places.

FFU high-efficiency filter structure features:

Attachment: FFU related knowledge:
FFU, also known as Fan Filter Unit, is a modular end air supply device with self powered and filtering capabilities. The fan sucks in air from the top of the FFU and filters it through the FFU high-efficiency HEPA filter. The filtered clean air is evenly sent out at a wind speed of 0.45m/s ± 20% on the entire outlet surface. FFU high-efficiency filters are widely used in semiconductor, LCD manufacturing, electronics, and biopharmaceuticals Waiting for the industry.
FFU fan filter unit usage environment:
Surrounding temperature: 5 ℃~40 ℃ Humidity: below 85% RH (without moisture condensation) Surrounding air: general indoor air cleanliness: level 100-10 Please avoid continuous and repeated ON/OFF operation of the machine.

FFU fan filtration unit product introduction:
The fan filtration unit FFU is a ceiling mounted unit with an internal fan, used in turbulent and laminar clean rooms. It has the characteristics of modular connection and can be used. The average wind speed on the outlet surface reaches 0.45m/s ± 20%.
Outstanding features: long lifespan, low noise, maintenance free, low vibration, gear speed regulation, and the ability to connect and control thousands of units.
Strict control: Before leaving the factory, all products are tested according to the international standard ISO14644-1, and FFU high-efficiency filters are scanned and inspected one by one with a dust particle counter to ensure quality.

How long does it usually take to replace the FFU matched high-efficiency filter?
What is the replacement cycle for FFU matched high-efficiency filters?
1. The primary filter screen should be cleaned once a week and replaced every six months. The medium filter screen does not need to be cleaned and should be replaced every quarter. The high-efficiency filter should be replaced once a year.
Note: The above replacement frequency is adjusted according to the operating time and cannot be fully referenced due to cost factors. It refers to a cleanroom that operates 24 hours a day. It is also closely related to the operating environment of the air conditioning cabinet, and maintaining the cleanliness of the computer room is crucial, for reference only.

2. The resistance of the sub high efficiency filter has exceeded the rated initial resistance by 100Pa, or is equal to 2 times the design or operating initial resistance (3 times for low resistance sub high efficiency) for more than 1 year. If it exceeds the standard, it can be replaced at any time.

3. The resistance of the coarse and low efficiency filter has exceeded the rated initial resistance of 60Pa, or is equal to 2 times the design or operating initial resistance for 3-6 months. If it exceeds the standard, it should be replaced at any time. The coarse filter should be checked weeklyMedium efficiency filterClean the return air outlet device once.

4. Replace the initial and intermediate filters every 6 months. Replace the high-efficiency filter every year. If the resistance of the medium efficiency filter exceeds the rated initial resistance of 80Pa, or is equal to 2 times the design or operating initial resistance for 6-12 months, replace it at any time if it exceeds the standard.

5. The resistance of the high-efficiency filter has exceeded the rated initial resistance of 160Pa, or is equal to 2 times the design or operating initial resistance for more than 3 years. If it exceeds the standard, it can be replaced at any time. The installation of high-efficiency air filters in operating rooms should comply with the following regulations:

High efficiency filterThey are high-efficiency filters without partitions and with partitions, high-temperature resistant high-efficiency filters, combined sub high efficiency filters, ultra high efficiency filters, DOP with liquid tank high-efficiency filters, knife holder high-efficiency filters (dense pleated high-efficiency filters/combined high air volume high-efficiency filters), ULPA ultra high efficiency filters. High efficiency air filters can be customized according to customer specifications and sizes!
