BT3-0154 Fan – 14 Inch Reversible, 12V

The BTRAC BT3-0154 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 M146K platform and uses a 14-inch low-profile axial design to deliver strong airflow while maintaining minimal installation depth.

Because the fan is reversible, it can operate as either a pusher or a puller, depending on system layout. As a result, it adapts easily to condenser, radiator, and auxiliary cooling applications. 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 sealed motor tested to DIN EN 60529 and rated IP68, which protects against dust and water intrusion. Therefore, it performs reliably in environments exposed to moisture, debris, vibration, and temperature extremes. The housing uses glass-filled nylon construction to provide strength and durability in demanding mobile applications.

Furthermore, the BT3-0154 delivers up to 1,555 CFM at zero static pressure, while maintaining stable current draw as static pressure increases. Because of this performance profile, it serves as a dependable OEM-style replacement fan for high-demand mobile cooling systems.
