Pocket Air Filter / Bag Filter – High-Capacity Filtration for HVAC and Industrial Ventilation
When it comes to air filtration in large commercial and industrial HVAC systems, efficiency, dust-holding capacity, and durability are crucial. That’s where the Pocket Air Filter, also known as the Bag Filter, excels. Designed for high-volume airflow and extended service life, the Pocket Air Filter / Bag Filter is the preferred solution for air handling units in buildings, factories, hospitals, and cleanrooms.
❓ What is a Pocket Air Filter / Bag Filter?
A Pocket Air Filter (also called a Bag Filter) is a multi-pocket, high-efficiency filter used in HVAC systems to remove fine dust, pollen, mold spores, and airborne contaminants. Made of synthetic or fiberglass media, each "pocket" expands under airflow, creating a large filtration surface area that allows for excellent dust retention with low pressure drop.
These filters are commonly used in:
-
Air Handling Units (AHUs)
-
Rooftop Units (RTUs)
-
Cleanroom pre-filtration
-
Commercial and industrial ventilation systems
