Straightening Door Vanes

To produce more consistency in dry work, it is recommended that door straightening vanes be added to the gate box door and the fairing in front of the gate. Door straightening vanes come in five-piece kits made specifically for gate box door size.

To learn more about straightening vanes and spreaders visit our spreaders page.

Straightening Vanes for Fairings

The Straightening Vanes for fairings are designed to smooth the airflow around the plane’s gate box, reducing turbulence and drag. This allows for more airflow through the spreader.

Spacers

Gate Box Spacers are components that maintain a consistent distance between the gate box and the spray valve, allowing a smooth, regulated flow. All valve-to-gate box spacers are 4″ wide and available in various hole pattern attachments to meet the different gate box configurations.

Sump Drains

A sump drain is designed to collect and remove excess liquid that accumulates in the gate box. Strategically positioned at the lowest point where the liquid will likely accumulate, the sump helps prevent liquid from standing in the gate box. Sump drains are available in both front and back configurations, offering flexibility to suit various installation requirements.

Metering Plate, Seeder Plate, and Dump Plates

Gate Box Accessories

Metering Plates

When applying small quantities of granular materials (50 lbs or less), metering plates can be inserted into the gate box to regulate and disperse the desired flow rate. These plates are designed to provide precision in applications requiring low distribution rates.

Important Safety Notice: Be aware that using metering plates may restrict the pilot’s ability to dump a load quickly in an emergency. This potential limitation should be considered in safety planning and operational procedures.

The Transland Meterate™ is an Excellent Tool for Low-Poundage Granular and Seed-Based Products.

Learn more about the Meterate.

Seeder Plates

Seeder Plates bolt onto the inside of the gate box door. They work in tandem with the box’s opening size to control the flow rate of material, such as seeds or granulated fertilizers. Seeder Plates give the pilot control over the desired amount of material distributed efficiently during the application process.

One of the key features of the seeder plates is their versatility and convenience. They are designed to remain attached to the door even when switching to liquid applications. This means operators don’t need to remove the plates when transitioning between different types of materials, saving time and effort during the process.

Dump Plate

The Transland Dump Plate efficiently jettisons the hopper’s contents. Featuring quick-disconnect flanges, this system allows rapid equipment change-over and easy removal for inspection or repair. The Transland Dump Plate is specifically designed to integrate seamlessly with the Q.D. flanges for smooth operation. Once the quick-disconnect flanges are installed on both the hopper and gate box, transitioning between the gate box and dump plate takes just minutes.

Demand Vents and Gaskets

Gate Box Accessories

Demand Vents

Demand Vents help equalize pressure within the hopper as materials are dispensed during flight. When material is released, the internal pressure inside the hopper can decrease, potentially creating a vacuum effect that disrupts the smooth flow of materials.

By allowing air to enter the hopper, Demand Vents maintain consistent internal pressure, preventing the formation of a vacuum and allowing materials to flow smoothly and evenly.

Regular maintenance and inspection of Demand Vents are essential to ensure optimal performance. Blockages, wear and tear, or damage to the vents can lead to operational disruptions and safety risks.

Transland Demand vents are available in Aluminum, Delrin, and Stainless Steel.
