The ultra-thin Uni-grid support can complement any thin, low-profile air filter assembly while maintaining the sleek filter design throughout the entire cross-section. Other expanded metal grids contain louvers that can get caught on chassis edges during installation and removal, but the Uni-grid support’s smooth surface will slide in and out of equipment easily. Once installed, the Uni-grid will reduce bowing and bulging commonly found in the center of filter assemblies. The support adds durability and ruggedness to the filter assembly and has been designed to a high open-area percentage in order to maximize the allowable airflow through the filter.
