The abbreviation for DC FFU purification unit is Fan Filter Units, which means "fan filter unit (unit)" in Chinese. That is to say, the fan and filter (HEPA or ULPA) are combined together to form a self powered end purification device. More precisely, it is a modular end air supply device with built-in power and filtering function. The fan sucks in air from the top of the FFU and filters it through HEPA. The filtered clean air is evenly sent out at a wind speed of 0.45m/s ± 20% on the entire outlet surface.

Overview of DC FFU purification unit:

The DC FFU purification unit has a long working time, low noise, maintenance free, low vibration, stepless speed regulation, uniform wind speed, and easy installation.

DC FFU can be modularly connected and used, making it widely used in cleanrooms, cleanroom workstations, cleanroom production lines, modular cleanrooms, and local Class 100 applications.

FFU is equipped with primary and high-efficiency two-stage filters. The fan sucks in air from the top of the FFU and filters 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. The DC FFU purification unit provides high-quality clean air for cleanrooms and microenvironments of different sizes and cleanliness levels. In the renovation and renovation of newly built cleanrooms and cleanrooms, the cleanliness level can be improved, noise and vibration can be reduced, and the cost can be greatly reduced. Installation and maintenance are convenient, making it an ideal component for clean environments.

DC FFU fan filter unit, with adjustable FFU wind speed, actual current LED display, fault alarm, overload protection functions, and can be set with local control (i.e. single unit control) and remote centralized control function (RS485). The flexible and versatile control methods make FFU control more arbitrary.

Application of DC FFU purification unit:

FFU is suitable for manufacturers of semiconductors, electronics, flat panel displays, and disk drives, as well as optical, biotechnology, and other places with strict control requirements for air pollution. Quickly occupy the market with unique advantages and reasonable prices.

Characteristics of DC FFU purification unit:

1. FFU dimensions (mm): 1175 * 575 * 320, noise level 52-56 decibels;

2. The FFU box and high-efficiency filter adopt a split design, making installation and replacement more convenient and efficient;

3. The fan adopts German DC centrifugal fan or domestic aluminum impeller centrifugal fan, with a working time of more than 50000 hours;

4. And it has the characteristics of energy saving, centralized computer control, stable operation, low noise, digital adjustment, etc;

5. FFU adopts a unique air duct with uniform wind speed, and the entire air outlet surface is uniformly sent out at a wind speed of 0.45M/s.

6. The shell can be made of mirror stainless steel, aluminum zinc coated plate, or cold plate electrostatic spraying to create a beautiful and elegant appearance;

Before leaving the factory, FFUs are scanned and tested one by one using a laser particle counter according to the US Federal Standard (209E) to ensure quality;

FFU is suitable for cleanrooms ranging from 10 to 10000 levels, facilitating centralized control of overall operation;
