FFU clean room or FFU HVAC operation to provide purified air by controlling the concentration of dust levels, temperature, humidity as well as the pressure level in a strict manner. Thanks to the FFU, hepa filter or fan, FFU, which will save the investment cost, the more space for customers to use compared to 1 HVAC system normally. Join us to learn FFU what is and why your business should invest system the blower Fan Filter Unit right now.

Equipment FFU what Is?

FFU is the acronym of Fan Filter Unit only the name of a device filter active air supply purified air to a room or a certain area needs cleaning.

For example, FFU clean room is usually installed in the ceiling of the clean room, assembly fan, FFU for hospitals, operating room, the lab. Or use FFU, hepa filter for the laboratory, the area modulation or production areas, medicinal, application for factory production of electronic components – semiconductor. The production unit, electronic circuit, Chip,motherboard, etc.

> clean Room, what is the standard clean rooms you need to know

In addition, Fan Filter Unit can directly use take fresh air from outside, without taking from HVAC systems, from AHU or FCU. Many places, fan, Fan Filter Unit is installed above the work of production workers, modulation or research,…etc.

In the production area of the plant often airflow after being cleaned will go through the HVAC system or AHU. But in the factory or the production area, the research practice often used in research or to produce more products, at the same time at the same time. This did happen to cross contamination, therefore, the fan, FFU are typically installed at the right on the ceiling of each area. So will separate each zone separately enhance the effect level airflow clean and avoid the risk of cross infection.

Principle of operation of the FFU clean room

There are 2 processes occurring in the theory of operation of the FFU:

smoking process: Use the fan Fan Filter Unit to suction air from the outside in. Users can filter the rough side on the fan to filter large dust particles to help the air filter more quickly and HEPA filter work more efficiently.
Push process: intake air will be pushed through the HEPA Filter or Ulpa Filter then put the clean air into the clean room with the velocity of 0.45 m/s +20%.

So Fan Filter Unit will take the air or fresh air from the AHU to filter clean level for clean room. Gas system will circulatory and always ensure the quality of gas.

The structure of the FFU clean room

FFU clean room usually designed to include the main parts after:

box, FFU: effect to protect the blower Fan Filter Unit and fixation location as well as design of other parts.
Mask soi anal Fan Filter Unit to evenly diffused air flow direction vertically down below the area that needs cleaning.
Fan, FFU: propeller System, Fan Filter Unit, this effect draws the air, and then push the air flow passing through the filter plate.
Membrane filter FFU: there are many types of membrane filter different to fitting inside the clean room equipment. Often use of the primary filter, the secondary Filter is located in front of the plate Filter, HEPA Filter or Filter, ULPA . FFU hepa filter will remove the tiny particles with sizes of 0.3 micron level filtration performance can reach 99.97% of.
Controller fan Fan Filter Unit: controllers for fan operation in the levels low, medium, or high level according to the needs of use.
Electronic controller to control operations for the entire FFU.

Design and installation of FFU HVAC for clean room

ffu-phong-sach

FFU HVAC can be mounted directly onto the ceiling in the form of independent. Or a combination of Fan Filter Unit with chamber system blowing cold supply air flow straight for clean room at high level.

Selecting FFU hepa filter: filter membranes used for Fan Filter Unit will have different thickness depending on the differential pressure. If user type membrane filter for Fan Filter Unit is too thick or high differential pressure is not exactly does airflow difficulty go down or disperse air evenly for effective poor.

So the version FFU hepa filter is often the form of mini-pleat with the design differences of thickness as well as the number of folds on a standard frame.

Advantages of FFU clean room

product structure, Fan Filter Unit, light weight with corrosion resistant, high smooth surface. Prevent secondary pollution, low air resistance and sound insulation.
Low noise and low vibration.
Low height should save room space when installation, the possibility of re-use can be sealed and preserved, then use back to normal.
Suitable for manufacturer has grid system easy change the size of the structure of the Fan Filter Unit according to the Grid system.
Diffuser sheet in the device fan, Fan Filter Unit, keep the air pressure spread in average room with wind speeds were steady.
Efficiency of the motor, low power consumption, should help users to save energy costs.
Can increase or change in a flexible way clean room by arranging the filter Fan.

However, the equipment clean room FFU there are also disadvantages is the cost of the initial investment is quite high and can arise breakdown difficult maintenance.

On this is the no. 1 information detailed interpretation equipment FFU what are the advantages of FFU clean room as well as characteristics filter, FFU, hepa filter.
