WL Series Operations Video
WL Series Vacuum Filters are designed for a variety of industrial and semiconductor process applications. The WL Series is ideal for medium-high vacuum furnaces and vacuum coating applications. All WL Filters comes standard with NW (also known as KF or QF) and ISO flange options and replaceable filter elements that offer great protection and longevity for long process vacuum systems. All Housings in this series are 100% helium leak tested to ensure vacuum integrity to 1x 10-5 mbar/l/s.
