The StreamShield EMI vent panel has a thin layer of intumescent
coating in the vent's honeycomb cells. When exposed to flames or heat at 300F,
the coating expands rapidly, filling the cells with carbonaceous foam that
prevents flames from propagating through the honeycomb.
The vents are typically used on telecommunication, data
communication, and other electronic rack cabinets. The HEICF 1594 coating helps
enclosures meet the requirements of network equipment building systems and
Bellcore GR-63-CORE physical protection standards for fire resistance. The
coating also meets ASTM E-84 Test procedures.
StreamShield EMI vents provide more than 50 dB shielding
effectiveness from 1 to 10 GHz. Open area of the honeycomb is 85% with the
The framed vents are available for round and rectangular opens.
Additional features include integral conductive mounting gaskets, compression
shops, and studs for push-in attachments.
