A fan filter unit (FFU) is a of type of air filtering equipment. It is used to supply purified air to cleanrooms or microenvironments by filtering out harmful airborne particles from recirculating air. The units are installed within the system's ceiling or floor grid. Large cleanrooms require a proportionally large number of FFUs, which in some cases may range from several hundred to several thousand units often contain their own pre-filter, HEPA filter and internally controllable fan air distribution.

compressed air filter
1). Separator filter (HF9)
For bulk liquid removal plus a 3 micron coalescer (5ppm w/w maximum remaining oil content)
Two-stage filtration
* First stage: two stainless steel orifice tubes provide 10 micron mechanical separation
* Second stage: in-depth fiber media captures solid and liquid particles to 3 micron
2). Air line filter (HF7)
For removal of liquid water and oil; removes solid particles to 1 micron (1.0 ppm w/w maximum remaining oil content)
Corrosion resistant inner and outer cores
Two-stage filtration
* Firt stage: captures larger particles with alternate layers of fiber media and media screen
* Second stage: coalesces aerosols and captures solid particles with multiple layers of epoxy bonded, blended fiber media
3). High efficiency oil removal filter (HF5)
For coalescing fine water and oil aerosols; removes solid particles to 0.01 micron (0.01 ppm w/w maximum remaining oil content)
Corrosion resistant inner and outer cores
Two stage filtration
* First stage: multiple layers of bonded, blended fiber media for fine coalescence

The material of HEPA Filter Air Filtration is mainly made of ultra-fine glass fibre as filter material, hot melt glue as separator, assembled with all kinds of outer frame, beautiful appearance, compared with the high efficiency filter with partition, under the same air volume, has the advantages of small volume, light weight, etc.
With the development of clean technology, high-efficiency air filters are changing rapidly in terms of filtration materials, structural forms, sealing materials, outer frame materials and testing methods. In particular, the rapidly changing production of integrated circuits requires a production environment with a particle diameter of 0.05 - 0.1 �¼m and an air cleanliness level of 1 or even more stringent, and also controls molecular-level chemical pollutants and heavy metal pollutants in the production environment.
Precautions for use
Pay attention to regular maintenance during use, pay attention to the surface and internal cleaning of the unit and replace the HEPA Filter Air Filtration regularly. Use clean cleaning utensils, such as rags, troughs and detergents, with appropriate strength and without excessive rubbing of the interior. Only with good regular maintenance and regular cleaning can the service life be extended. Folding filter to do regular replacement, reduce the resistance of the filter operation, greatly reduce the cost of the enterprise, save a lot of electricity costs.
The replacement cycle of high efficiency filters is generally in accordance with the recommended service life of the supplier's instructions, while the replacement cycle is adjusted according to the cleanliness level, high efficiency protection status, pollution level and product risk, and requires regular high efficiency leak detection and replacement according to high efficiency leak detection or high efficiency filtration before and after pressure difference. If the HEPA air filter is damaged, it can be repaired in accordance with the regulations, and should be replaced if it does not meet the requirements.
Application areas
With the development of industry, people's awareness of living in an environmentally friendly environment has increased, which has also played an active role in promoting the healthy development of clean business and regulating clean room construction and acceptance. Nowadays, clean technology has been greatly developed, and has expanded from the high, precise and sophisticated industrial clean room as the main application area back then, to the broader field of industrial clean rooms, general biological cleanliness and isolated biological clean rooms today.
