Ceiling Mount Hepa Fan Filter Unit With EMB DC Motor , Free Maintenance For One Year


Fan filter unit (FFU) is a type of motorized air filtering equipment. It is used to supply purified air to cleanrooms, laboratories, medical facilities or microenvironments by removing harmful airborne particles from recirculating air.[1] The units are installed within the system's ceiling or floor grid. Large cleanrooms require a proportionally large number of FFUs, which in some cases may range from several hundred to several thousand. Units often contain their own pre-filter, HEPA filter and internally controllable fan air distribution

5. Material: armor plate, stainless steel;
6. Adjustable speeds;
7. Excellent performance ;
8. Using a highly-efficient centrifugal air blower;
9. Durable, low noise, low vibration;
10. Free maintenance for one year

Concept of FFU development:
1. To reduce running cost by saving energy;
2. To reduce construction cost and term by thin, light and compact structure;
3. To reduce initial cost by total design of clean room including noise spec. etc;
4. We development FFU units basing upon the above concept to meet all the requirements for constructing, operating and maintaining clean rooms.

Advantage of clean room with FFU:
1. The construction period can be shortened;
2. The degree of cleanness from class 10 to class 1000 can be set and the degree of cleanness can be set at each area;
3. Because the back in the ceiling is a low-pressure, the potential of the leakage is low;
4. Bay method or through the wall method is possible by the arrangement of layout of FFU;
5. The velocity of the air flow can be set at each area;
6. Flexible increase or change of the clean room is possible by the arrangement of FFU.
