What is an FFU? You are wondering how the FFU is structured, what are the specifications, and the advantages it offers for cleanroom. Let's find the answer with VCR

What is FFU?

FFU (Fan Filter Unit) is an air cleaning device, used to provide clean air to cleanroom in the plants of semiconductors, liquid crystal diodes, etc. Fan filter unit is installed on the grid ceiling system. In large cleanrooms, the number of equipment needed ranges from hundreds to thousands.

Concept of FFU development

1. To reduce operating costs by saving energy

2. To reduce construction costs because of thin, light, and compact structure of fan filter unit

3. To reduce the initial cost of the overall cleanroom design like the noise ...

-> FFU has been developed to comply with requirements for cleanroom construction, operations, and maintenance.

1. Box cover

2. Fan

3. Filter

4. Mask

What are the advantages of a cleanroom having FFU?

1. Construction time can be shortened

2. Cleanliness level from class 1 to class 1000 can be set differently in each area

3. Because the opposite part of the ceiling has low pressure, the potential for this leakage is low

4. The arrangement of FFU partly decides the cleanroom construction method

5. The velocity of the airflow can be set in each area

6. Flexible increase or change of the cleanroom is possible due to the arrangement of the fan filter unit.
