Initial Pulse Testing of Cartridge Medias in Accordance with Accelerated VDI 3926

This research was undertaken to get initial results on the performance of Arioso® high performance air filtration composite media designed for use in pulse-cleanable cartridges. These tests compared Arioso M7001-11 (designed for F9 efficiency) against M3203-11 designed for H12 efficiency) and Sample A, an industry leading ePTFE media using pulse testing equipment built in accordance with VDI/DIN 3926. The first test rig was of the Type 1 (vertical duct) style and second rig was of the Type 2 (horizontal duct) style.
