Applications
- Fan Filter Unit (FFU) is air cleaning equipment to supply purified air to the clean room for manufacturing photo-electronics, semi-conductor, liquid crystal, etc.
- The installation space is the system ceiling grid.
- For a large clean room, the number of required FFU is from several hundreds to several thousands.
- We developed DEVISER Fan Filter Unit(FFU)basing upon the concepts including, to reduce running cost by saving energy, and to reduce initial cost by total design of clean room; such as noise specifications etc., to meet all the requirements for constructing, operating, and maintaining clean rooms.
- Custom thin & Mini type of Fan Filter Unit is available for your requirements.
Advantages of clean room with Fan Filter Unit method
- The degree of cleanliness from class 1 up to 100,000 can be set and it can be set at individual area.
- Because the back in the ceiling is a low-pressure area, the potential of the leakage is extremely low.
- Bay method or through the wall method is possible by the arrangement of layout of FFU.
- The volume of the air flow can be set at each area.
- Flexible increase or change of the clean room is possible by the arrangement of Fan Filter Unit.
Features
- A 3 - section or variable speed airfoil turbo fan made by aluminum alloy, which pursued the most suitable designed by computer analysis, provides high efficiency and low-noise characteristics.
- A carrying handle makes transportation and installation easier.
- A safety socket block for connecting electric power is most suitable for a small clean room system.
- An optional ULPA filter, which is 99.9999% efficiency at 0.12 microns, is available to meet the extremely critical clean area needs.
