AA1282MB-AT ADDA 230V AC Axial Fan 120x120x38mm

Description

The ADDA AA1282MB-AT is a high-reliability industrial AC Axial Fan with dimensions of 120 x 120 x 38 mm. Driven by a specialized Shaded Pole Induction Motor, this model is engineered to operate directly on a nominal 230 VAC supply. It delivers a steady maximum airflow of 77.0 CFM (130.8 m³/h) at 50 Hz and up to 90.0 CFM (152.9 m³/h) at 60 Hz. With a power input of 20.0 W, it is specifically designed as a primary thermal management solution for industrial enclosures where DC power is unavailable. This model features a premium dual-ball bearing system and a 5-blade high-torque impeller housed in a robust die-cast aluminum frame, which facilitates superior motor heat dissipation. Equipped with two-terminal termination (AT), the AA1282MB-AT provides mission-critical durability for industrial inverters, power distribution cabinets, and heavy-duty machinery requiring constant 24/7 cooling.

Application
The AA1282MB-AT is primarily utilized as a robust cabinet cooling fan for industrial frequency drives, CNC controllers, and high-voltage power distribution systems. Its die-cast aluminum housing provides exceptional structural integrity and acts as an auxiliary heat sink for the induction motor, which is crucial in high-ambient-temperature industrial environments. The “AT” terminal design allows for rapid and secure electrical integration using standard spade connectors, streamlining the assembly of large-scale electrical panels. This 230V fan is essential for maintaining consistent air circulation in elevator control systems, industrial welding machines, and telecommunications racks, where the dual-ball bearing system ensures long-term maintenance-free operation under 24/7 mission-critical conditions.
