Low-cost monitoring system for AC or DC fans & blowers

The AFM series provides an economical solution for indicating fan or blower airflow. The AFM module operates an optical LED or audible alarm when airflow falls below 8.2 ft/s due to fan filter clogs or foreign materials coming in contact with the fan blade. Field retrofittable for AC or DC fan/blower applications, this air flow sensor protects components like power supplies, PoE midspans and displays in sensitive equipment including servers, telecom switches, medical equipment and kiosks. An AFM Kit is also available including an AFM-01NC, clip, three plastic guards (80, 92, & 120mm), buzzer, LED and holder, switch and power supply.
