Shielded Air Ventilation Panels
Air filter panels, with honeycomb design mounted in an extruded aluminum edge frame, electronically shields ventilation openings of equipment enclosures with minimum pressure drop.


Shielding Express Air Vent Panels are constructed using aluminum honeycomb mounted within a C-channel edge frame. The panels are supplied ready to mount on the shielded enclosure via a composite EMI/RFI shielding gasket attached to the panel frame. The panel edge frame has a mounting hole pattern for either through-bolts or captive insert receptacles.

All panels are made to customer specifications.
