FFU refers to fan filter unit and can be modularized, which makes it widely used in clean rooms, clean benches, clean production lines and assembling clean rooms, local class 100 environment, etc.
FFU is equipped with primary and high efficiency filters. Air is sucked into the fan from the top of the FFU, filtered by the primary and high efficiency filters and then sent out from the fan outlet at a uniform velocity of 0.45M/S±20%. FFU is suitable for high-level clean environments and serves as an ideal facility for purifying environment. It can provide high-quality clean air for clean rooms and micro-environments of different sizes and different cleanliness levels, improve cleanliness level and reduce noise and vibration in newly-built clean rooms and renovated clean workshops, reduce costs greatly and facilitate installation and maintenance.
Generally speaking, the clean room system contains an air duct system, an FFU system and an axial flow fan system;
Compared with the air duct system, the FFU system has six advantages:
(1) flexible (2) recyclable (3) capable of negative pressure ventilation (4) shortening construction period (5) cutting down on operating cost (6) saving space.
In clean rooms with their cleanliness level being 1,000-grade (FS209E standard) or Level ISO6 above, as well as in locally clean environment, clean cabinets and clean benches, the FFU system is usually used.
1. FFU is especially suitable for assembling into super-clean production line. It can be arranged as a single unit according to the process needs, or multiple sets can be connected in series to form a 100-stage assembly line.
2. FFU fan filter unit adopts external rotor centrifugal fan, which has the characteristics of long life, low noise, no maintenance, small vibration and stepless speed regulation. Suitable for obtaining a higher level of clean environment in various environments.
3. FFU for different areas, different levels of clean room, micro-environment to provide high-quality clean air. In the new clean room, clean workshop or renovation, it can not only improve the cleanliness level, reduce noise and reduce vibration, but also greatly reduce the cost. Easy to install and maintain, is the ideal component of clean environment.
4. Shell structure is made of high quality aluminum-zinc plate, light weight, corrosion resistance, rust prevention, beautiful and generous.
5. FFU laminar flow cover is scanned and detected according to E,METOME U. S. federal standard 209 dust particle counter to ensure quality.
6. FFU laminar flow hoods are in accordance with the US Federal Standard 209E, and METOME dust particle counters are scanned and tested one by one to ensure the quality.
