Also known as FFU fan filter unitIt is a ceiling unit equipped with an internal fan, used in turbulent and laminar flow clean rooms, with the characteristics of modular connection, and the air outlet surface wind speed reaches 0.45m/s ± 20%. A coarse and efficient two-stage filter can be set at the top. The working principle is that the fan sucks in air from the top of the FFU and filters it through a coarse and high-efficiency filter. The filtered clean air is evenly sent out through the air outlet surface at an average wind speed of 0.45m/s.

FFU fan filtration unit product features:

Low energy consumption, high static pressure, can adopt multi-stage or stepless speed regulation, low operating cost.

Adopting a special flow channel and uniform flow system design, it has the characteristics of low noise and uniform wind speed.

Lightweight, adopting a cover in installation method, making installation, filter replacement, and maintenance more convenient.

Using a dedicated fan, it has a long service life, is basically maintenance free, and can achieve computer group control and remote control functions.

In the construction, renovation, or renovation of clean rooms and workshops, it can improve cleanliness levels, reduce noise and vibration, greatly reduce costs, and is an ideal device for clean environments.

The shell structure can be made of electrostatic spraying materials such as stainless steel, aluminum plate, aluminum zinc plate, and cold-rolled steel plate, which have the advantages of light weight, corrosion resistance, rust prevention, and beautiful appearance.

Outstanding featuresLong lifespan, low noise, maintenance free, low vibration, and stepless speed regulation.

Strictly controlBefore leaving the factory, the products are scanned and tested one by one using a dust particle counter in accordance with the international standard ISO14644-1 to ensure quality.

applicationsWidely used in manufacturers of semiconductors, electronics, flat panel displays, disk drives, optics, biotechnology, clean production lines, clean workbenches, clean rooms, modular clean rooms, laminar flow hoods, and other places.

Our FFU group control features:

The human-machine interface host adopts a display screen to achieve remote monitoring and adjustment of FFU. It can easily achieve FFU multi unit and partition control. It can achieve the start stop and speed regulation functions of any number of FFUs, and the speed regulation function can be digitized by directly inputting the expected wind speed value (such as 10%. 20%, etc.) to achieve the purpose of speed regulation. Capable of monitoring the current of any FFU. When there is a fault FFU alarm, it can display the location of the fault FFU in real time. The computer monitoring center adopts an on-site interface method. Through communication with the monitoring host, when any one or more FFUs fail, the on-site interface of the computer monitoring center will sound an alarm to quickly determine the location of the faulty FFU, ensuring that monitoring personnel can handle the fault in a timely manner.

Partition control method:

According to the actual system requirements, each host is divided into six zones for control, with each zone corresponding to a group of FFUs (the system stipulates that the maximum number of fans per group is 32). The control functions are as follows:

1. To control the start and stop of a certain group of fans in the entire clean room, the wind speed of a certain group of fans can be uniformly set.

2. Control the start and stop of a certain fan in the entire clean room, and set the wind speed of a certain fan.

3. The number of fans in a certain group can be set.

4. Query the operating status of a certain fan in the entire clean room, such as the start stop status of the fan and the operating wind speed of the fan.

5. Overload protection function: Automatic remote alarm when overload occurs.
