Liquid tank sealed FFU | detachable FFU

The liquid tank sealed FFU and detachable FFU fan filtration unit are a new type of FFU specially developed by Guangzhou Zijing Company according to the strict requirements of GMP clean rooms in some pharmaceutical factories. The FFU fan and high-efficiency filter are separable, and the working principle is the same as that of ordinary FFUs. The fan sucks in air from the top and passes through itFFU high-efficiency filterAfter filtration, clean air is evenly distributed to provide clean air and particle filtration control for a clean environment.

FFU (Fan Filter Unit) is a combination of a fan and a filter, also known as a "built-in fan filter device". FFU is usually installed at the end of the clean room's air supply, and is usually placed on a suspended "dry" gasket sealing keel frame. The upper part of FFU is the fan module, and the lower part is the filter. According to the requirements of cleanliness, the filter can be a high-efficiency (HEPA) or ultra high efficiency (ULPA) filter of different grades, providing clean air for the cleanroom. The fan module not only needs to overcome the resistance of the high-efficiency filter at the bottom of the FFU, but also needs to overcome the resistance of all channel components of the entire circulating air to maintain the set operating wind speed. The FFU system has the characteristics of simple design and construction, flexible wind speed adjustment, and easy change of clean areas, making it one of the popular system forms in industrial cleanrooms.

The FFU laminar air supply unit module can be connected and used, making FFU widely used in clean roomsclean benchClean production lines, modular clean rooms, andlaminar hoodWaiting for application scenarios. FFU is equipped with primary and high-efficiency dual pole filter screens. The fan sucks in air from the top of the FFU and passes it through primary and high-efficiency filters. The filtered clean air is sent out at a constant speed of 0.45m/s ± 20% on the entire air outlet surface.

Liquid tank sealed FFU is a new type of FFU developed according to the needs of customers. Widely used in manufacturers of semiconductors, electronics, flat panel displays, disk drives, optics, biotechnology, clean production lines, clean workbenches, clean rooms, modular clean rooms, laminar flow hoods, and other places.

Liquid tank sealed FFU | features of detachable FFU:

1. The bottom of the filter separation FFU adopts a special design of fixed parts, which makes it convenient and fast for one person to operate when installing, disassembling and replacing the filter.

2. Adopting an efficient AC centrifugal fan, the average wind speed increases by 25%, and the overheating protection ability is good, effectively reducing losses.

3. Stable wind speed and long service life. Suitable for cleanrooms with a cleanliness level of Class 1-1000.

4. It is particularly suitable for assembling into ultra clean production lines, and can be arranged as a single unit for use according to process needs, or multiple units can be connected in series to form a 100 level assembly line.

5. Unique liquid tank sealing method, equipped with PAO dust emission port and concentration sampling port, fully meets the requirements of the new GMP-E specification. Lightweight and slim body, more convenient for application in small areas.
