02. Bag or Pocket Medium-Efficiency Air Filter

What is a cleanroom bag&pocket medium-efficiency air filter?

Cleanroom bag&pocket medium-efficiency air filters are specialized air filters designed for use in cleanroom environments. They are typically made of high-quality synthetic media that effectively captures airborne particles and contaminants, preventing them from entering the cleanroom space. These filters are available in bag or pocket configurations, which allow for a large filtration area, resulting in higher dust-holding capacity and longer filter life.
The bag-type air filter has 3-12 parallel bags, and the bag depth is generally 250~900mm. Ultrasonic welding between individual bags. Such a process ensures that the airflow can pass through the entire filter more efficiently and the dust is efficiently loaded and evenly distributed. This extends filter life and reduces energy costs. And a grid can be arranged in the inner bag of the filter to effectively increase the filtering area.

How do bag&pocket medium-efficiency air filters work?

Cleanroom bag&pocket medium-efficiency air filters work based on the principle of mechanical filtration. The synthetic media used in these filters is designed with varying fiber diameters and layers to create a tortuous path for the air to pass through. This traps and retains particles of different sizes, including dust, pollen, mold spores, bacteria, and other airborne contaminants. The filters typically have a high initial efficiency and are capable of achieving an average efficiency of 60-90% for particles in the range of 1-10 microns, depending on the filter class.
