FFU’s full name in English is (FanFilterUnit), and its Chinese name is fan filter unit.
FFU fan filter unit can be connected and used in a modular manner. Clean room FFU filter membranes are widely used in clean rooms, clean workbenches, clean production lines, assembled clean rooms and local level 100 applications.
The clean laboratory is a fully enclosed environment. Through the primary, secondary and high-efficiency filters of the air-conditioning supply and return system, the indoor ambient air is continuously circulated and filtered to ensure that airborne particles are controlled to a certain concentration.
The main function of a clean laboratory is to control the cleanliness, temperature and humidity of the atmosphere that products (such as silicon chips, etc.) are exposed to, so that products can be tested and scientifically researched in a good environmental space.
So clean laboratories are usually also called ultra-clean laboratories, clean laboratories, purification laboratories, etc.
Clean room FFU filter membrane refers to a microporous film made of polytetrafluoroethylene as raw material and using special processing technology through calendering, extrusion, biaxial stretching and other methods.
This kind of membrane has excellent breathability, corrosion resistance, aging resistance, high temperature resistance and other properties.
According to the usage requirements, the pore diameter can be between 0.1-10um, the thickness can be between 2-100um, the porosity can reach 50%–80%, and there are up to hundreds of millions of micropores per square centimeter.
The highest accuracy can reach H14 level (99.995%) or above. Since the micropore diameter is tens of thousands of times larger than water molecules and hundreds of times smaller than water droplets, it has excellent moisture permeability, air permeability and waterproof properties.
PTFE film manufacturer specializes in the production of clean room FFU filter membranes. It has a full set of advanced production equipment and technology. It also has an advanced clean room and an independent composite slitting workshop to ensure the production quality of PTFE membrane.
