The difference between the clean room and clean booth(Modular clean room)

More and more customer prefer easy installed clean booth(Modular clean roo, softwall clean room as named) for cost saving, to keep a clean area space.

Then Anlaitech company engineer would take more information about clean booth to share, if any professional in clean room trade, we would much appreciated your comments !

Thank you for reading.

The difference between the clean room and clean booth(Modular clean room)

 

1. Clean booth material :

Framework of clean booth generally three types:50*50/50*80/50*100 stainless steel square but, iron with epoxy powder coated in square tube , 40*40 aluminum.
The top shelf material of clean booth generally four types: stainless steel plate, cold rolled steel spray epoxy, anti -static air curtain, (anti-static ) acrylic plate .
Airflow Supply Parts, the general choice FFU laminar flow hood (FFU laminar flow air supply unit )
Walls of clean booth materials generally include: anti-static air curtain, ( anti-static ) acrylic plate.

2.Clean booth purification level of choice:

More customers will choose 1000class clean booth(Modular clean room), or 10000class clean booth, a small number of customers will choose one hundred or ten thousand clean class clean booth. In short , clean booth-level choices depends on customers requirements, but relatively clean booth sealed closed, such as when selecting clean booth level is relatively low, often bring some side effects : insufficient cooling capacity, staff feel more hot in the clean booth, so the actual and the customer communication process , need to pay attention to this point.

3. The cost of the clean room and clean booth comparison:

Overall, most customers will built clean booth in the clean room, but some customers do not want to build a clean room, clean booth does not consider air conditioning system and air shower room, pass box these cleaning equipment, etc. the cost of clean booth is about 40% to 60% of the clean room cost, also depending on the customer 's choice of clean booth material, as well as the size of the clean booth. The larger the area needs, with a clean room cost difference will be smaller compared.

4. clean booth advantages:

A. Construction fast, easy installation
B. low cost , easy maintenance
C. easy to control , FFU each comes with fan;

5. clean booth drawbacks:

A. because of the extensive use of FFU air filtration units , so clean booth noise may be relatively large ;

B. FFU own fans, to maintain high frequency, but most clean room choose FFU own fans instead of HEPA filter box also maintain high frequency;

C. due to space airflow supply , clean shed inside will often feel hot ;

D. If not clean booth built in the clean room, due to the lack of protection in effect filter, high efficiency filter life compared with the clean room, will be shortened, the higher the cost of long-term use.

What is the FFU (laminar flow hood)?

What is the FFU (laminar flow hood)?
FFU (Fan Filter Unit) is a combination of fan and filter can also be called “Motorized HEPA filtration equipment”. FFU are usually installed in the supply end of the clean room, usually placed on the T-grid with gasket sealed. FFU upper part is the fan module, the lower part is the filter. Accordance with the requirements of cleanliness filters for different levels of efficiency (HEPA) or ultra-efficient (ULPA) filters provide clean air for the clean room. Fan modules overcome the resistance of the HEPA filter, but also to overcome the resistance of the whole cycle all channels of wind components in order to maintain the set running speed. Design and construction of FFU system with simple characteristics, flexible air flow adjustment, easy to change in the clean area, so the system has become one of the popular forms of industrial clean room.

FFU (laminar flow hood) Features:
1: Flexibility. Because limiting FFU self-powered, it is not limited by region. In a huge clean room can divided into zoning control according to need. Moreover, with the change in the semiconductor manufacturing process, plant layout is bound to be adjusted accordingly, flexibility FFU makes this adjustment easier, and will not bring secondary investments.

2: Reusability. If the FFU no need use at moment can be removed, sealed, safekeeping for next using.

3: Negative pressure ventilation. This is the unique characteristics of FFU, because of its own to provide anti-static, making relative to the clean air plenum plant negative, thus, the particles inside static pressure under pressure will not leak to clean area, make sealant becomes very simple and safe.

4: Shorten the construction period. Eliminating the need for the use of FFU duct fabrication and installation because the air duct in a clean project, takes up a lot of the construction period , any investor wants to invest as soon as possible to bring income , the choice of FFU become a possibility .

5: To reduce operating costs. Although the selection of FFU, the initial investment than with high ventilation duct, but during running, the outstanding performance of energy-saving, maintenance-free characteristics, with a 40% reduction in cycle operating costs.

FFU (laminar flow hood) external residual pressure (ESP): In a set speed, the total static pressure FFU (TSP), net of HEPA / ULPA filter resistance, that is external residual pressure (ESP), the unit is Pa. ESP is the FFU ability to overcome resistance in the clean room air circulation, either dimension the overall static TSP FFU and pressure or fan outside the machine module are required supply airflow volume, or no meaning.
Input energy (input power consumption): normal operation of FFU input voltage and input current the unit is W. Obviously, FFU that run at different condition of airflow volume and total static pressure, enter a different energy. Therefore, if you do not specify the operating point, the value of the input energy does not make sense.
Unit noise (noise level): according to the standard IES-RP-CC002, the normal operation of the FFU from the surface of the wind noise level at the center is 1.2mm below the unit is dB (A). FFU run at different conditions of airflow volume and total static pressure, different noise. Therefore, if you do not specify the operating point, the noise level does not make sense.

FFU (laminar flow hood) fretting (micro vibration): According to the standard IES-RP-CC002, FFU vibration amplitude and vibration rate at the maximum operating conditions point unit are mm and mm / s.

Uniformity air velocity (air uniformity): according to the standard IES-RP-CC002, the normal operation of FFU, the distance by measuring the surface side of the wind 150mm (6 ") of the horizontal surface wind speed, the average value of the obtained average wind speed. minimum and maximum wind speed and air deviation than is uniformity in units of + / - % standard IES-RP-CC002 FFU required air velocity at any point of its average wind speed deviation should be within + / - 20% or less .

Air Filter efficiency (filter grade): according to the European standard EN1822, HEPA Filter class from H10-H14, U15-U17. Or according to the American standard MIL-282 (HEPA), for 0.3um efficiency values ​​; according to the American standard IES-RP-CC007.1, for 0.12um efficiency values.

Plant scale evaluation form

                                                      Plant scale evaluation form (1) – production capacity assessment

- Note: the factory according to their own situation, choose plant size evaluation form ( 1 ) / ( 2 ) one of which can be filled when the factory can not provide financial documents to confirm the size of the factory proved , the auditor should use this factory recommended methods for evaluation.
- The auditor must clearly explain to the factory to use this table, and afterwards as factory disagrees with the results of the assessment should be modified only by formal financial documents to prove to the TÜV.

- Capacity assessment form based on actual production or product production capacity to fill the last year of the factory by the manufacturer , in an audit , the auditor checks should be required , the manufacturer is obliged to provide the relevant production records ( eg : production of certain products monthly statistics report ) to prove the authenticity of the filled contents.

- If the capacity of the following claims in doubt, but the factory can not provide sufficient proof, TÜV and GMC audit staff reserves the right to specify the capacity suspicious in the report.

3. The structure’s characteristic and element

    1. The structure’s characteristic

As the sketch map, the Flow Workstation makes up of cabinet, centrifugal fan, HEPA filter and operational on-off. The cabinet material use cold board plastic coated. The clean cells use the wind system that can change wind power. Through this process of changing, the average wind speed in the clean working area will keep in a rated range (0.3~0.45m/s). This can prolong the using time of air filter.

2. The element of working

The airs go through the pre filter, then into the pressure cabin by centrifugal fan, and go through the hepa filter at last. At this time, the clean air could come out and flow to the working area. The pressure in the working area is not same, so this can prevent the dust from outside. In order to enlarge the area of purification, we’d better use a dispersing component at air exit.
