Air Flow Switch
MODEL :- RC-F62AA
“RC” flow switch is designed to detect airflow in ducts by responding specifically to the velocity of air movement. When air comes into contact with the paddle, the spdt (single pole double throw) contacts activate making or breaking an electrical circuit based on whether the airflow starts or stops. This ensures accurate and reliable monitoring of ventilation and hvac systems.
Can Be Used In :
- Air duct
- Fast Shut down on Air duct heaters to guard against burning failure
They can be wired to close circuit and open a second circuit. When Air flow either exceeds or drops below the adjusting flow rate.
