Clean Room Equipment —— FFU

The full English name of FFU is (Fan Filter Unit), and the Chinese professional term is fan filter unit. The FFU fan filter unit can be used in modular connection. The use of FFU is widely used in clean rooms, clean workbenches, clean production lines, assembled clean rooms and local 100-level applications.

FFU is equipped with primary and high-efficiency two-stage filters. The fan inhales the air from the top of the FFU and filters it through the primary and high-efficiency filters. The filtered clean air is sent out at a uniform speed of 0.45M/S±20% on the entire air outlet surface. Suitable for obtaining a high level of cleanliness in a variety of environments. It provides high-quality clean air for clean rooms and micro-environments of different sizes and cleanliness levels. In the renovation and renovation of new clean rooms and clean workshops, it can improve the cleanliness level, reduce noise and vibration, and greatly reduce the cost. It is easy to install and maintain, and it is an ideal component for a clean environment.

The following advantages of FFU itself make it quickly applied:

1.     Flexible and easy to replace.

Install and move FFU is self-contained and modular, and the matching filter is easy to replace, so it is not restricted by the area; in the clean workshop, it can be controlled by zone according to need to be replaced and moved.

2.     Negative pressure ventilation This is the unique feature of FFU.

Since it can provide static pressure itself, the clean room is positive pressure relative to the outside world, so that external particles will not be leaked into the clean area, making sealing very simple and safe.

3.     Shorten the construction period.

The use of FFU saves the production and installation of air ducts and shortens the construction period.

4.     Reduce operating costs.

Although the initial investment of FFU is higher than that of using air duct ventilation, in the later operation, it prominently shows the characteristics of energy saving and maintenance-free.

5.     Space saving

Compared with other systems, the FFU system occupies less floor height in the air supply static pressure box, and basically does not occupy the clean room space.
