The design of dual-EMI filters promotes necessary enclosure ventilation while simultaneously providing EMI/RFI shielding. The aluminum-framed filters feature an open-cell polyurethane foam filter media specially coated to provide improved flame retardation. All-aluminum components may be coated with a clear chromate conversion finish to make them conductive. In addition to providing desired shielding, the air filters meet UL 94 HF-1 flame retardancy requirements.
