Air Flow Switch For Exhaust Fan

An air flow switch for an exhaust fan is a device that is used to measure the amount of air that is flowing through the fan. It is designed to detect changes in air flow and activate the fan when the air flow drops below a certain level. This helps to ensure that the fan is running at an optimal level and is not overworking itself. The air flow switch is usually connected to the fan motor and is triggered when the air flow drops below a certain level. This helps to ensure that the fan is running efficiently and not wasting energy. The air flow switch can also be used to detect when the fan is not working properly, such as when it is blocked or not running at the right speed. This helps to prevent the fan from overworking itself and potentially damaging the motor.
