Dallas, Tex. – Orion Fans has introduced a cost-effective airflow monitoring system that provides a simple alternative for indicating airflow in AC or DC fan/blower applications. The AFM Series 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, the AFM airflow sensor protects components like power supplies, PoE midspans, and displays in sensitive equipment including servers, telecom switches, medical equipment and kiosks. It is also well suited to MRO applications since it can be “easily retrofitted into existing systems,” said Orion Fans.
Placed on the output or input side of the fan, the AFM module mounts perpendicular to airflow via a clip, clamp or integration into a fan guard. It measures positive airflow by mounting in the front of the fan or negative airflow when mounting to the intake side of the fan. The module can be purchased already assembled to a grill, or sold separately to mount on any fan or blower grill. The plastic finger guard fits fan size configurations of 80 mm, 92 mm and 120 mm.
The RoHS-compliant AFM Series measures 34 mm x 17.5 mm x 7.5 mm. The operating temperature range is -20 degree C to 50 degree C. The module offers a long operating life of more than 100,000 cycles. It is rated to IP20 and is NEMA 1 certified to protect against dust and indirect splashing.
