EMI Air Vent Filter

EMI Air Vent Filter

Features

EMI Air Vent Filter plays roles of both ventilation (heat discharge) and countermeasure against EMI in shield rooms, chambers, electronic enclosures and so on. The choice of material for EMI Air Vent Filter is greatly determined by EMI SE, performance of heat discharge and dimension of devices.

Applications

  • Network Server
  • Personal Computer
  • Cooling Fan Cover
  • Access Equipment
  • High Speed Routers
  • Storage Cabinets
