Application of FFU in cleanroom

FFU is equipped with primary and HEPA filters. The fan draws air in from the top of the FFU and filters it through the primary and HEPA filter, and the filtered clean air is sent out at a uniform wind speed of 0.45m/s on the whole air outlet surface. It is suitable for obtaining high-level clean environment in various environments. It provides high-quality clean air for different sizes and cleanliness levels of clean rooms and microenvironments. In the new clean room, clean plant type renovation renovation, not only can improve the cleanliness level, reduce noise and vibration, but also can greatly reduce the cost, easy to install and maintain, is the ideal parts of the clean environment.

Why use FFU system?

1. Flexible and easy to replace, install and move

FFU is self-powered, the supporting filter is easy to replace, so it is not restricted by the region; In the clean workshop, zoning control can be carried out according to needs, and replacement and movement can be carried out according to needs.

2. Negative pressure ventilation

This is a unique feature of FFU. Because 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 the sealing very simple and safe.

3. Shorten the construction period

The use of FFU eliminates the production and installation of air ducts and shortens the construction cycle.

4. Reduce operating costs

Although the initial investment in the selection of FFU is higher than the use of air duct ventilation, it highlights the characteristics of energy saving and maintenance-free in later operation.

5. Save space

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

Classification of FFU

Classified according to the box material

According to the different materials of the box, it can be divided into - standard coated steel plate (including galvanized, aluminum plated zinc, aluminum plate spray, etc.), stainless steel plate, aluminum plate (aluminum alloy plate), other materials.

Classified by motor type

According to the motor classification, it can be divided into AC motor and brushless EC motor. AC single-phase motor code A1; AC three-phase motor code A3; The EC brushless motor code is EC.

FFU fan selection

FFU fans can be selected from EC fans (EC) and AC fans (AC).

1, AC fan selection

AC FFU uses a manual speed control, because its initial investment is relatively small, commonly used in the clean room of less than 200 FFU.

2, EC fan selection

2、Selection of EC fan

EC FFU is suitable for clean rooms with a large number of FFUs, using computer software to intelligently control the operating status and faults of each FFU, saving maintenance costs, each set of software can control multiple main gateways, and each gateway can control multiple FFUs.

EC FFU can save more than 30% energy than AC FFU, and the annual energy saving for a huge number of FFU system is very considerable. At the same time, EC FFU also has the characteristic of low noise.
