FFU fan filter unit powered HEPA filter module for cleanroom

FFU fan filter unit | FFU fan powered HEPA filter module for cleanroom

FFU fan filter unit, also called FFU fan filter unit, is a ceiling-mounted unit with an internal fan. It is used in turbulent and laminar flow clean rooms. It can be used in modular links. The wind speed on the outlet surface can reach 0.45m/s± 20%. A coarse and high-efficiency two-stage filter can be set on the top. The working principle is: the fan sucks the air from the top of the FU and filters it through a coarse and high-efficiency filter, and the filtered clean air is evenly sent out through the air outlet surface at an average wind speed of 0.45m/s.

FFU fan filter unit product features:

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

It adopts special flow channel and equalizing system design, which has the characteristics of low noise and uniform wind speed. Light weight, the use of hood-mounted installation method makes installation, filter replacement and maintenance more convenient. It adopts special fan, which has long service life and is basically maintenance-free. It can realize computer group control and remote control functions.

In the new clean room, clean workshop or renovation and renovation, it can not only improve the cleanliness level, reduce noise and vibration, but also greatly reduce the cost. It is an ideal device for a clean environment. The shell structure can be made of stainless steel, aluminum plate, galvanized plate and cold-rolled steel plate by electrostatic spraying material, which has the advantages of light weight, corrosion resistance, rust resistance and beautiful appearance.

Features:

1.      long life, low noise, maintenance-free, low vibration, stepless speed regulation.

2.      Strict control: The products are scanned and tested one by one with a dust particle counter in accordance with the international standard ISO14644-1 before leaving the factory to ensure the quality.

3.      Applicable fields: Widely used in semiconductor, electronics, flat panel display, disk drive manufacturers and optical, biological industries, etc., clean production lines, clean workbenches, clean rooms, assembled clean rooms and laminar flow hoods and other places.

Advantageous:

The man-machine interface host adopts the display screen to realize the remote monitoring and adjustment of the FFU. It can easily realize multiple FFU and partition control. It can realize the start, stop and speed regulation functions of any number of FFUs, and the speed regulation function can be digitalized, that is, directly input the expected wind speed value (such as: 10%, 20%, etc.) to achieve the purpose of speed regulation. It can monitor the current of any FFU. When there is a faulty FFU alarm, the location of the faulty FFU can be displayed in real time. The computer monitoring center adopts the on-site interface mode, through communication with the monitoring host, when any one or more FFUs fail, the on-site interface of the computer monitoring center alarms, quickly determines the location of the faulty FFU, and ensures that the monitoring personnel deal with the fault in time.

Partition control mode:

According to the needs of the actual system, each host is divided into six areas for control, and each area corresponds to a group of FFU (the system stipulates that the number of fans in each group is at most 32).

The control functions are as follows:

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

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

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

4. Inquire about the running status of a fan in the entire clean room, such as the start and stop status of the fan, and the running wind speed of the fan.

5. Overload protection function: When overload occurs, it will automatically alarm remotely.
