In recent years, as the purification engineering industry has begun to focus on two-way acceptance standards for product quality and stability, clean room FFU filter membranes have made outstanding contributions to some high-level purification environments.
In clean laboratories, mechanical equipment clean rooms and general biological clean rooms are maintained by positive pressure, but for clean laboratories that use toxic and harmful gases or flammable and explosive solvents and other special requirements, negative pressure is used control.
Maintaining a certain positive pressure in a clean laboratory is one of the necessary conditions to ensure that the clean room is free from or less contaminated and maintains the designed cleanliness level.
Even if it is a negative pressure clean room, a certain positive pressure must be maintained in the adjacent room or suite not lower than its cleanliness level, so as to maintain the cleanliness of the negative pressure clean room.
Clean room FFU filter membrane is suitable for various clean rooms from level 1 to level 100000. It adopts a special processing technology and is a microporous film made by 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.
It is a clean room FFU filter membrane manufacturer that specializes in R&D, production and sales.
