Bag & Pocket Medium-Efficiency Air Filter

Bag and pocket medium-efficiency air filters are types of air filters that are designed for use in cleanrooms and other controlled environments. Cleanrooms are specialized environments that are designed to minimize the presence of contaminants, such as dust, bacteria, and other particles. In a cleanroom, air filters are used to remove particles and contaminants from the air, in order to maintain the cleanliness of the environment.
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.
Bag and pocket medium-efficiency air filters are designed to remove particles and contaminants from the air with a medium level of efficiency. This means that they are able to remove a wide range of particle sizes, from larger particles such as dust and dirt to smaller particles such as bacteria and viruses. They are typically used in cleanrooms and other controlled environments where a medium level of cleanliness is required, such as in pharmaceuticals, medical devices, and semiconductors.
Bag and pocket medium-efficiency air filters are typically made by enclosing a filter media, such as fiberglass or synthetic fibers, within a perforated metal or plastic frame. The frame is then sealed with a plastic or rubber gasket to prevent air leakage. The filter media is typically coated with a layer of adhesive, which helps to capture and remove particles and contaminants from the air.
When choosing a bag or pocket medium-efficiency air filter, it is important to consider the specific requirements of your cleanroom, such as the size and shape of the cleanroom, the level of cleanliness required, and the types of hazardous materials that will be used. By carefully evaluating these factors, you can determine the right bag or pocket medium-efficiency air filter for your needs.

Youth’s bag air filters are designed to be used in primary/mid-stage/high-stage air filtration equipment. Extended Surface Unsupported Bag Filters are designed for use in air filtration systems and equipment requiring medium to high efficiency filtration. Youth is available in a variety of standard sizes, face sizes, pocket counts and depths to provide optimum performance in a constant airflow air handling system.

What is Different Between a Bag or Pocket Air Filter?

Bag air filters and pocket air filters are both types of air filters that are commonly used in cleanrooms and other specialized environments. While both types of filters are designed to remove particles and contaminants from the air, there are some key differences between them.

One of the main differences between bag air filters and pocket air filters is their construction. Bag air filters are typically made by enclosing a filter media, such as fiberglass or synthetic fibers, within a perforated metal or plastic frame. The frame is then sealed with a plastic or rubber gasket to prevent air leakage. In contrast, pocket air filters are made by enclosing the filter media within a series of pockets or compartments that are sewn or welded together.

Another key difference between bag air filters and pocket air filters is their performance. Bag air filters typically have a lower initial resistance and a higher dirt holding capacity than pocket air filters, which means they can remove more particles from the air while still allowing air to flow through the filter. Pocket air filters, on the other hand, typically have a higher initial resistance and a lower dirt holding capacity, which means they are more effective at removing smaller particles from the air but may restrict air flow more than bag air filters.

When choosing between a bag air filter and a pocket air filter, it is important to consider the specific requirements of your application. For example, if you need a filter that can remove a large amount of particles from the air while still allowing air to flow through the filter, a bag air filter may be the better choice. If you need a filter that can remove smaller particles more effectively, a pocket air filter may be a better option. By carefully evaluating your needs, you can determine the right type of air filter for your application.
