Constructed with a coarse pre-filtration outer layer, an ultra-fine meltblown core, and a protective synthetic backing. This graduated density traps larger particles upstream, preventing premature clogging and extending operational lifespan.
Optimized for ultrasonic welding and hot-melt production lines. Seams withstand static pressure surges up to 600 Pa without rupture or bypass leakage.
Built-in internal spacer ribs prevent pocket deformation and pocket-to-pocket touch under variable airflow, ensuring uniform face velocity and complete dust utilization across the entire media surface.
Available in standard industry colors matched to filtration efficiency classes for easy quality inspection and warehouse management.
