BAG AIR FILTER / POCKET AIR FILTER

Bag or pocket filters serve a crucial role in HVAC systems, effectively eliminating dust from ambient air. Typically, they function as final filters in commercial settings or act as prefilters for HEPA systems, particularly in hospitals and the Pharmaceutical Industry.

Structure and Variability

Constructed by sealing together pieces of media, these filters take the form of pockets. Each bag filter can feature a specified number of pockets, such as 3-pocket or 6-pocket variants. Additionally, the pockets themselves can vary in length, allowing for diverse surface area sizes to be created.

Impact on Performance

The combinations of pocket numbers and lengths directly influence the surface area of the filter. Generally, a larger surface area translates to an improved Dust Holding Capacity (DHC) and extends the service life of the filter. This correlation underscores the significance of surface area in enhancing the filter’s efficiency and durability.

Applications and Versatility

Bag or pocket filters find widespread application beyond HVAC systems, proving beneficial in various industries like pharmaceuticals, manufacturing, and food processing. Their versatility lies in effectively capturing contaminants and particulate matter, contributing to cleaner and safer environments across diverse industrial settings. With their adaptable configurations and superior dust retention capabilities, these filters play a pivotal role in maintaining air quality standards and ensuring optimal working conditions in critical sectors.
