A high-temperature pleated HEPA panel for clean ovens, coating lines and laminar flow units where the supply air must stay clean.

A high-temperature pleated HEPA panel is a process filter, not a filter that merely tolerates heat. It sits at or near the terminal position on a clean oven, a curing or coating line or a laminar flow unit, so the air leaving it reaches the product with nothing behind it to catch what it passes. It is therefore judged on the particle removal the process needs, and on whether it still holds that performance after weeks at temperature.

What makes it survive is the seal rather than the media. The ultrafine glass fiber pleat pack is held in a metal frame, and the joints are closed with a flexible sealing material in place of rigid ceramic adhesive, because a seal that cannot move with thermal expansion is the part that cracks, peels or leaks as the unit cycles. Selection turns on the continuous temperature the filter actually sees rather than the peak the oven can reach, and on the grade the process cleanliness requires. Change-out follows differential pressure, but the seal should be inspected at the same time: a lifted seal bypasses the media, and a pressure gauge will not show it.
