Communication Filters

communication filtersGenisco communication filters are low-pass Electromagnetic Interference and Radio Frequency Interference filters (EMI & RFI) designed to block high-frequency noise that interferes with the operation of sensitive electrical equipment. 

These high performance dual circuit filters are available for both DC and AC applications including: 

  • Telephone
  • P.A. System 
  • Fire Alarm
  • Relay/Thermostat
  • General Communication 
  • Data

These standalone filters are built with a gasketed pipe to penetrate into a shielded environment (shielded rooms, screen rooms, SCIFs, secure environments, etc.) to maintain emission integrity.
