Introduction of Fan Filter Unit

Fan filter unit is a device for cleanroom, it comes with fan / motor, HEPA filter. HEPA filter remove fine dust with good efficiency 99.99%, fan to help airflow overcome the resistance of HEPA filter. Fan filter unit air velocity is adjustable, 3 level adjustable. Also the ffu can be controlled centralized by computer system. Most of the FFU are made of metallic housing, stainless steel / painted metal plate and so on.

for cleanroom / for clean devices / for clean booth


Most frequent application for the cleanroom Fan Filter Unit

FFU is a modular terminal air supply device with built-in power and filtration efficiency in the clean booth.There are various levels of cleanliness and spatial collocation in the clean booth, so the FFU in the clean booth can provide local air purification equipment in a high clean environment.Clean room is mainly composed of box body, fan, primary air filter, damp layer, lamp, etc.The clean booth can be hung and supported on the ground. It is compact and easy to use.It can be used individually, or multiple connections can be made into a strip clean area to reduce costs.

Advantages of the clean booth: the air is sucked into the air by the fan from the top of FFU and filtered by the primary filter and high efficiency filter. The filtered clean air is sent out to the clean booth at a constant speed of 0.45m/s + 20% across the entire air outlet surface.A uniform flow layer is formed to make the clean air flow presents a vertical one-way flow, thus ensuring the required cleanliness in the work area.Can be used alone or in combination.Modular structure, easy to improve cleanliness, strong expansibility, and high reuse value;


The quality of food and the standards around it are constantly improving, and the safety of food depends on the production technology and production environment. The food industry has very severe requirements on the processing environment and production environment of food.Many manufacturers in the food production workshop have built cleanroom as the isolation of outdoor pollution. While, Just build a clean room can’t completely discharge pollutants, fan filter unit is needed to maintain cleanliness level, clean air be sent in uniform wind by FFU, so, most food production manufacturer will order a certain number of Fan Filter Unit.

The medical industry demands a high degree of cleanliness. Many experiments and surgeries can only be carried out in a specific environment of high cleanliness.

The FFU purification unit can guarantee this well.

In the biopharmaceutical industry, although compared with the electronics industry, the requirements for the overall purification level are not high, but for the control of dust particles and bacteria pollution, generally the sterile room needs to be equipped with a 100-level laminar flow hood to protect, and these environmental cleanliness guarantee cannot be separated from the FFU purification unit.

The electronics industry, due to the nature of products and user experience, pay special attention to the clean environment in the production workshop.Industries like electronics, flat-panel displays and semiconductors are long – term users of FFU cleaning units.

All of our high-end phones are made in a clean room, and the FFU cleaning unit is an effective guarantee of their quality
