BT3-0153 Fan – 12 Inch Reversible, 12V

The BTRAC BT3-0153 axial fan is engineered for mobile HVAC and equipment cooling systems operating on 12-volt electrical platforms. It is based on the Maradyne Champion Series M123K platform and uses a 12-inch low-profile axial design to deliver high airflow while keeping installation depth to a minimum.

Because the fan is reversible, it can operate as either a pusher or a puller, depending on the application. As a result, it adapts easily to condenser, radiator, and auxiliary cooling layouts. In addition, the quiet S-Blade fan design is dynamically balanced, which helps reduce vibration and operating noise during continuous duty.

The fan uses a long-life sealed motor rated IP68, protecting it from dust and water intrusion in extreme environments. Therefore, it performs reliably in on-highway trucks, off-highway equipment, and vocational vehicles exposed to moisture, debris, and vibration.

Furthermore, the BT3-0153 delivers 1,155 CFM at zero static pressure, while maintaining efficient current draw across increasing static pressure. Because of this balanced performance, it serves as a dependable OEM-style replacement fan for high-demand mobile cooling systems.
