BT3-104-4 Blower Assembly – 24V Double Squirrel Cage

Description

The BTRAC BT3-104-4 blower assembly is built for mobile HVAC systems that operate on 24-volt electrical platforms and demand consistent airflow. It uses a double squirrel cage fan design, which helps move air evenly across heater cores and evaporators while maintaining stable performance.

Because the blower features three operating speeds, it allows operators to adjust airflow based on comfort needs and system demand. As a result, cab temperature control remains smooth and predictable. In addition, the counter-clockwise (CCW) rotation supports common HVAC layouts used in heavy-duty trucks, buses, and specialty equipment.

The compact housing and mounting base make installation straightforward, even in tight spaces. Therefore, the BT3-104-4 works well in both OE replacement and retrofit applications. The vented motor design also helps manage heat during extended run times, which supports dependable operation in demanding environments.

Furthermore, this blower assembly crosses to well-known OEM and aftermarket part numbers, including SPAL 30006706, which makes it a practical service replacement for fleet maintenance programs.
