FILTRATION
Medium to High Vacuum Filtration
WL Series ISO Flanges NW16-NW40, K63-K100
Overview
Solberg’s WL Series Vacuum Filters are designed for a variety of industrial and semicon processes where rapid thermal and/or pressure cycles create harsh operating conditions. Ideal for medium-high vacuum applications that utilize vacuum furnaces or deposition tools, the WL series comes standard with a variety of vacuum rated flange options and replaceable filter elements that offer superior protection and longevity for the vacuum system.
Housings in this series are 100% helium leak tested to ensure vacuum integrity and verify leak rates down to 1x10-5 mbar L/s.
