Description
The Nonwoven Pocket Filter is engineered for medium-efficiency air filtration in commercial, industrial, and institutional environments.
Constructed from high-quality synthetic nonwoven filter media using advanced ultrasonic welding technology, the filter pockets maintain their shape during operation and ensure uniform airflow distribution across the entire filtration surface.
The progressive-density media structure allows particles to be captured throughout the depth of the filter, resulting in higher dust holding capacity, longer service life, and lower energy consumption.
Designed for use as a secondary filtration stage after pre-filters, pocket filters effectively remove fine dust, pollen, fibers, and airborne contaminants before air enters sensitive environments.
