Description
Glass Fiber Media HEPA/ULPA is made of fine glass fibers. It has a dense, multi-layered structure that enables it to capture tiny particles (down to 0.3μm) with efficiency up to H11-U16 grades.
It features high temperature resistance (up to 250℃), low wind resistance, and long service life. It’s widely used in HEPA/ULPA air purifiers, industrial dust collection, and precision electronic manufacturing.
