Resideo 4074ETH Flow Switch Els PW 17895 Reliable Switching: Utilizes normally closedThe Resideo 4074ETH Flow Switch is a critical sensing component engineered specifically for F50 and F58 Series Electronic Air Cleaners. This differential pressure switch serves as the primary interlock, ensuring the air cleaner cells are only energized when sufficient HVAC system airflow is detected. This prevents ozone buildup and protects internal components from premature failure due to static operation. The 4074ETH is a direct replacements for the
