The guard and retainer allows free passage of air (24CFM) with minimum air resistance and pressure drop. When the filter media requires maintenance you simply remove the snap-fit retainer to clean or replace the filter, leaving the guard attached to the fan. This assures protection to the fan blade and eliminates damage to the fan during cleaning.
