RadonAway Air Flow Alarm with Audible and Visual Alerts

The RadonAway battery powered air flow alarm monitors radon system operation. It mounts directly onto the system pipe to alert users of a low or no air flow condition. A thin, field trimmable vane installed within the pipe operates in air flow as low as 10 CFM in a 3” pipe and 15 CFM in a 4" pipe. An audible buzzer alternates with bright, flashing red LED light when there is no air flow in the pipe. This monitor does not measure radon levels.
