Filter material: high-quality chemical fiber filter material and glass fiber filter material, using high-quality glass fiber material, which not only effectively intercepts dust in the air, but also can be burned to generate carbon dioxide and water after use, without polluting the atmosphere. Special filter material and reasonable filter structure reduce the resistance to the lowest level.
Outer frame: aluminum profile, galvanized sheet, plastic frame, to meet the needs of different customers.
Filtration efficiency: There are four types: F5, F6, F7, and F8, corresponding to medium efficiency and medium efficiency, 40% to 90% of the colorimetric method. Filters of this efficiency can be used both as pre-filters in the protection class and as final filters in general ventilation and air-conditioning systems.
Scope of application: pre-filtration of industrial central air-conditioning and centralized ventilation systems, terminal filtration of industrial central air-conditioning and centralized ventilation systems, protection-grade filters for high-efficiency filters.

Medium-efficiency glass fiber pocket (bag) filters are used in the intermediate filtration stage of HVAC, AHU, and cleanroom air conditioning systems to reduce particulate loading and protect downstream HEPA filters. Featuring ultrafine glass fiber media and a multi-pocket structure, they can be configured according to airflow, efficiency, installation space, and allowable pressure drop for equipment integration and replacement projects.
Select the filter class and media according to project requirements to reduce fine particle loading. Performance should be supported by the relevant test standard and efficiency data.
Reduces particles reaching HEPA filters. Actual protection performance and replacement intervals depend on upstream filtration, dust loading, and operating hours.
The multi-pocket design provides a large filtration area. Assess dust-holding requirements based on pocket count, pocket length, and dust loading, allowing sufficient space for pocket expansion.
Configure the filtration area according to design airflow. Verify initial pressure drop and available fan static pressure to balance filtration performance and system operation.
Suitable for central air conditioning and cleanroom air handling units. Confirm airflow per filter, installation dimensions, and pocket arrangement during selection.
Replacement specifications can be standardized. Schedule replacement based on operating differential pressure and on-site inspections to simplify spare parts and maintenance management.
