FFU

Introduction：

FFU is an English abbreviation, full known as Fan Filter Units, Chinese meaning "fan filter units", is a kind of self-powered, with filtering effect of modular end air supply device. Its main function is that the air is inhaled by the fan from the top of the FFU and filtered by the HEPA. The filtered clean air is evenly sent out at the entire outlet surface at the speed of 0.45m/s soil 20%, so as to meet the clean requirements of the clean environment. It is mainly installed in the clean area, the ceiling keel of the working area and the equipment machine. It is widely used in semiconductor, optical electronics, precision instruments, biopharmaceutical, aerospace, automobile, hospital, food, spraying, printing and other fields.

FU 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.
