Benefits at a Glance:

  • Protects fiberglass hoppers from cracking during loading
  • Reduces in-flight movement of dry and liquid materials
  • Supports consistent performance in variable conditions
  • Simple, rugged solution with long-term structural benefits

Transland’s hopper baffle is a small addition that makes a big difference — protecting your equipment and enhancing your application performance.

Hopper Baffle for Thrush Aircraft

Structural Strength. In-Flight Stability. Long-Term Protection.

Transland’s hopper baffle for Thrush aircraft is built to protect and enhance the performance of your aerial application system. Whether loading dry or liquid material, this internal reinforcement helps prevent costly damage and supports consistent in-flight behavior.

Prevent Cracking During Loading

When filling the hopper with dry granules or liquid, especially at high speed or volume, the incoming material can create significant localized force. The baffle diffuses this impact, reducing stress on the hopper’s fiberglass walls and seams. This reinforcement helps prevent cracking or fatigue, especially in demanding operations with fast-fill systems.

Reduce Material Movement During Flight

Once in the air, the baffle also minimizes shifting of dry material and sloshing of liquid. This added in-flight stability helps maintain better aircraft handling and reduces sudden load shifts during turns, pull-ups, or turbulent conditions.

Hopper Vent

Hopper scoop vents are installed on the hopper and designed to improve airflow and facilitate smooth, consistent discharge of dry materials. The vent helps regulate internal pressure and prevents vacuum buildup, allowing air to enter as material exists.
