High Dust Holding Capacity Pre-Filter for HVAC Systems
COARTEX Coarse Bag Filters are designed for coarse particle filtration in HVAC and industrial ventilation systems. The multi-pocket bag design provides a large filtration surface area, allowing high airflow rates while maintaining low pressure drop and excellent dust holding capacity.
These filters are typically installed as the first filtration stage in air handling units (AHUs) to remove larger airborne particles such as dust, fibers, and lint. By capturing coarse contaminants, Coarse Bag Filters help protect downstream fine filters and improve the overall efficiency of ventilation systems.
COARTEX Coarse Bag Filters offer reliable performance in commercial and industrial applications where stable airflow, long service life, and economical filtration solutions are required.
