BT3-0201 Brushless Fan – 15″ 24V

Description

The BTRAC BT3-0201 brushless fan supports 24-volt mobile HVAC and cooling applications that demand high airflow, durability, and precise speed control. It is based on the SPAL VA91 – BBL341P/N platform and uses a sealed brushless motor with integrated electronics. As a result, it provides stable performance across a wide range of operating conditions.

Because the fan uses a brushless design, it runs efficiently and quietly while extending service life. In addition, the PWM / E digital input allows accurate speed control, which helps match airflow to system demand. Therefore, the fan performs well in condenser, radiator, and HVAC modules where airflow varies with load.

The 15-inch (Ø385 mm) axial blade moves high air volume, even under pressure. Meanwhile, the integrated protections—including over-current, over-temperature, and reverse-polarity—help protect the fan and the vehicle electrical system. Furthermore, the sealed construction supports IP6K9K and IP68 protection, which improves reliability in harsh environments.

Overall, the BT3-0201 is a dependable solution for trucks, buses, and off-highway equipment that require 24-volt, PWM-controlled brushless cooling.
