Air filters

Dual EMI/RFI Honeycomb air filters are for medical electronics enclosure applications. This system provides air filtration and EMI shielding in a single assembly that is compact and removable. The honeycomb structure consists of cells that are engineered to trap and absorb EMI noise while maintaining 95% to 99% openness for minimal airflow impedance.
