Filters are used in main and fine air filtration units for general ventilation and air conditioning equipment. - details see: https://www.machineto.com/hvac-self-supported-pocket-filters-10224946

The filter medium is constructed from selected high performance fibers in a progressive density multi-layering technique to ensure high depth loading with optimal lowest pressure drop performance. This result in long filter life and usage, high fractional efficiency combined with relatively high dust loading and low energy and maintenance costs.

The pocket media are inherently rigid. The bag edge is welded by national patented high-frequency technology. The welding edge is really leak-free when compare to the sewing way.With a welded rib construction to form pockets with the highest possible functional security in even the most brutal air-pressure and high dust-laden environments.
