USED FOR COOLING, VENTILATION, AND SPECIALIZED SYSTEMS
These filters (manufactured to meet MIL-PRF-16552) are cleanable, high-velocity impingement type metal filters. Dirt particles and fine lint in the air stream are collected on the filtering media by adhesion to a thin film of filter adhesive on the filter. These filters are located upstream of cooling coils, CBR filters, HEPA filters, flame arresters (flame arrestors require metallic Navy standard filters), and other specialized systems. After cleaning (washing, thorough rinsing, and drying) the Navy standard filters shall be recoated with a filter adhesive (except air filters used as grease filters in commissary spaces of some older ships should not be coated with a filter adhesive). A thin coat of air filter adhesive is applied to the inlet side of the filtering media so that dirt particles and fine lint will adhere to the filtering media.
