AUSFIL uses five main types of filter media as the foundation of our production line- Stainless Steel Woven Wire Mesh, Needle Punched Felt, Spunbounded Polyester, Micro-Fiberglass and Cellulose. Each media has its own level of performance, with varying levels of cost, capture efficiency, dirt holding capacity, differential pressure capability and system life. Below is a brief comparison chat that may help to assist making the right selection.
