Flexible and Long-Lasting

AAF's Universal Latches are available to hold a variety of filters and filter combinations in place to create a positive seal. They are specifically designed for upstream or downstream servicing. Each latch is annealed to music wire specifications after forming, and is commercially zinc-plated to provide years of service under varying environmental conditions. The latches are replaceable and easy to use, requiring only a simple twisting motion to release the filter. Double latches allow prefilters to be changed without disturbing the final filter.

Unique Design

Universal Holding Latches are designed to be used exclusively in combination with AAF's Galvanized Universal Holding Frames. UHF's feature a unique retaining tab to hold the “L” Series latches. “L” Series latches do not connect to, or disturb, the flat sealing flange and gasket surface.

The L-42 and L-44 latches, specifically designed for the VariCel® II filter in combination with a prefilter, offer an additional advantage. The latch can be turned to release the prefilter while maintaining a pressure seal on the higher-efficiency VariCel II filter.
