 Frameless Honeycomb ventilation panels 9505

EMI shielded ventilation panels for ventilation and heating without frame. Possible with compressed flange.


Honeycomb vents are used to EMI shield openings for ventilation or acoustic/visual contact. We can make these vents according to your drawing within a few days, or you can use our standard range from stock.


Honeycombs are also frequently used as flow straighteners to create a laminar flow.
