Bonfiglioli Trasmital 300M planetary gearbox cooling fan

To enhance the performance of its Trasmital planetary gearboxes, Bonfiglioli is introducing an integrated fan option for its latest 300M series. The fan is connected directly to the IEC motor, which leads to an improved thermal rating and increased thermal power of up to 217%, depending on the model.

Planetary gearboxes are staple workhorses for bulk materials handling, mining process equipment, food and beverage, materials handling, water treatment, waste handling and heavy industries. They typically use a low speed and high torque for good performance in a compact space.

The high levels of torque together with the compact nature of planetary gear units can lead to thermal restrictions, particularly in arduous conditions common in Australian industries. By running cooler than their predecessors, the gearboxes can safely utilise more torque.

A keyway hollow shaft connection for the fan means that no joint is required. Integrated fins optimise the airflow and cooling surfaces throughout the entire air conveyor housing.

The integrated fan is designed to fit any size Bonfiglioli or commercial motor. The 300M series has 100% interchangeability with Bonfiglioli’s current 300 series models, so no machine modification is required when upgrading to the later units.
