The IAC pleated filter is a one-piece element of spun bond polyester media. Because spun bond material is pleatable, we can get 200 300% more filter media into a pleated filter that is the same size, or usually smaller than the conventional filter bag it replaces. This dramatically reduces your air-to-cloth ratio, providing for a much more efficient operation of the collector. You will also see increased airflow, lower differential pressure, lower energy cost and higher filtration efficiencies.
