Description: This product is designed to alert users of low- or no-air conditions in pipes. The DAFA can monitor radon mitigation systems by detecting a loss of airflow in the pipe and providing a signal to the homeowners if the fan has stopped operating. It utilizes a thin, field-trimmable vane to sense the airflow rate in pipe sizes between 3 to 4 inches. The product is battery powered to provide versatility of installation location and offers a yellow LED to indicate a low battery. The battery can last up to five years when in a steady state. An 85 dB audible buzzer alternates with a bright red LED to alert users when the airflow drops below the desired rate.
