Overview

The nVent AAFM120NO Airflow Monitor (SKU: AAFM120NO) is a normally open (N.O.) airflow detection device engineered for Hoffman Cooling Fans in Bulletin D85-compliant systems. This device ensures precise airflow monitoring in industrial enclosures, preventing thermal overload in sensitive equipment such as electrical enclosures, control panels, and data center cooling systems. The AAFM120NO integrates seamlessly with Hoffman’s thermal management portfolio, offering a fail-safe configuration that alerts operators to airflow interruptions. Key specifications include a 120mm grille optimized for airflow detection, a high-impact plastic housing rated UL94-V0 for flame resistance, and a removable F5-grade filter with 98% efficiency for particles >10μm. The unit features a lockable door in the hood to prevent tampering, 2 lead wires (3.94 in / 100 mm) terminated with pressure clamps for wire gauges up to 14 AWG (2.5 mm²), and a synthetic filter material resistant to 212°F (100°C), 100% RH moisture, and self-extinguishing (class F1). The AAFM120NO is designed for durability and ease of integration, with an external mounting depth of 2.56 in (65 mm) and an enclosure cutout of 4.92 x 4.92 in (125 x 125 mm). With a service life of over 50,000 hours at 77°F (25°C) and 65% RH, the AAFM120NO reduces maintenance cycles and total cost of ownership, making it an ideal choice for facilities prioritizing uptime and reliability.
