Abstract
Official abstract text for this publication.
The present invention provides regenerable pleated media and filter elements and combinations thereof for use in a clean room environment for removal of airborne molecular contamination. Disclosed is a pleated filter media for a clean room environment wherein the pleated filter media comprises at least an adsorbent first layer of activated carbon or polymer wherein said activated carbon or polymer together with fibers and/or an adhesion agent is enclosed between two second layers of non woven with a grid positioned on at least one side of either of the second layers or incorporated in the first layer for preventing deformation of the pleated filter media when regenerated by a heated air flow above 100° C. at 1 atm.
First claim
Opening claim text (preview).
The invention claimed is: 1. An apparatus comprising: a heat resistant pleated filter media, which does not release particles above ISO Class 6 environment according to standard ISO 14644-1, for a clean room environment, the pleated filter media regenerable by heated air flow above 125° C. at 1 atm, said pleated filter media being heat resistant to melting and burning for temperatures of up to at least 190° C., and including: at least an adsorbent first layer of activated carbon…
