MAJR Products Corporation Vice President of Electrical/EMC Engineering, Michael J. Oliver, authored this white paper. The white paper presents airflow characteristics of electromagnetic and radio frequency interference (EMI/RFI) shielding honeycomb ventilation panels and dust filtration characteristics of dust filtration panels. For a System Engineer, airflow data helps to identify the correct panel size for electronic cooling applications. The Airflow data of these shielding honeycomb ventilation panels are presented as graphs of Static Pressure Drop (Inches H2O) vs. Airflow (CFM / Sq. inch).
