Lightweight and versatile aluminium honeycomb vents are supplied in a variety of styles to facilitate mounting requirements and any overall size. Panels are designed to provide minimum pressure drop of airflow through the assembly whilst giving good RF attenuation. Panels are normally supplied using two layers of honeycomb oriented at 90° to provide non polarised attenuation. Straight through panels can be supplied with plating to overcome the polarisation problem.
Vents can be fitted with conductive gasket for improved shielding effectiveness, drilled holes or threaded captive inserts to aid fixing & can also include separate dust filters and protective kick plates to prevent accidental damage. All panels finished in Alocrom 1200 to stop
oxidisation. Other finishes available to order.
EMC EMI LTD’s EMI shielding vent panels or attenuvents are made from aluminium or steel honeycomb mounted into a frame. Many aluminium frame styles are available together with different thicknesses and configuration of honeycomb to meet different shielding requirements. Protective grilles are available for vulnerable areas together with dust filtration foams. Many plated or painted finishes can be specified.
