Genisco 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.
