FFU Fan Filter Unit The HEPA Filter System Ceiling Of Cleanroom
Product Description
FFU is abbreviation of Fan Filter Unit. It is a modular terminal air supply device with its own power and filtering effect. Its main function is to inhale the air from the top of the FFU by the fan and filter it by HEPA, and the filtered clean air is evenly sent out at the air velocity of 0.45m/s+20% on the entire air outlet surface to meet the cleanliness requirements of the clean environment. It is mainly installed on ceiling keels and equipment machines in clean areas and working areas. It is widely used in semiconductors, optical electronics, precision instruments, biopharmaceuticals, aerospace, and automobiles, hospitals, food, spraying, printing and other fields.

FFU Features
Negative pressure ventilation
Because of its ability to provide static pressure, the clean room is positive pressure relative to the outside world. Therefore, external particles are not subject to leakage into the clean area, makes sealing easy and safe.
Save space
Compared to other systems,FFU system occupies less floor height in the supply air plenum.And basically does not occupy the clean room space.
Shorten construction period
Using FFU saves the production and installation of air ducts.Shorten the construction period.
Reduce operating costs
Although when choosing FFU, the initial investment is higher than using duct ventilation. However, in the later operation, it prominently shows the characteristics of energy saving and maintenance-free.
Convenient and fast control
Remote and precise control of single or group FFU, And it is not affected by other pipe network systems.
It is flexible and easy to replace, install and move
FFU is self-powered and self-contained modular.The matching hepa filter is easy to replace, so it is not restricted by the region: In the clean workshop, it can be installed, replaced and moved according to the needs, and it can be controlled by separated zone.
