AWS Airbar®

Driven by a purpose-built S3 AWS blower assembly, the Airbar® is a leader in high-efficiency, air-assist harvesting. The Airbar® model employs a single-channel, wraparound, closed-circuit air system. With the fan and chassis centrally located on the combine header and powered by the feeder house reverser gear, the airflow travels around the back of, and across the front of the header from a single airflow channel.

Available for both draper and auger headers.


  • Uniform 42” or 48” nozzles are contoured and optimized for each header model.
  • Does not interfere with with the factory reel.
  • Drive system optimized for in-field serviceability with industry standard components.
  • Drive ratio matched to combine model to ensure optimum airflow.
  • In-cab control of air throttle & nozzle position.
  • 2-piece nozzle construction with durable, lightweight die-cast mounting saddle.
  • Durable, 1 & 2-piece aluminum manifold.
  • Manifold is designed for each combine make and model.

The fans on all Airbar® Systems are powered by a purpose-built, high-efficiency belt drive system. The drive system was engineered to be easily accessible and provide smooth, efficient power.

Primary benefits

In harvesting Soy and Pulse crops, traditional headers incur shatter loss at the knife when loose and low-lying pods are impact-shelled and fall back into the field or are otherwise lost or damaged. This results in profit loss and reductions in sample quality. Knives are often cluttered with debris, reducing cutting efficiency and creating unnecessary wear, breakage and downtime.

When added to a combine header, the AWS Airbar reduces or eliminates this loss of product and efficiency. The high-velocity air stream that is applied to the knife through the out-front manifold, thrusts these pods and materials across the cutting head and into the feeder-house increasing yields by as much as 4 bushels per acre on average.

Improved feeding

The high-speed airflow keeps the cutting head clear and operating at maximum efficiency reducing equipment wear.

Reduced shatter loss

Air pressure keeps all loose product flowing into the feeder-house preventing these losses and increasing yields by as much as 4 bushels per acre.

Faster ground speed

Improving crop flow across the header, allows for substantial increases in ground speed.

Increased operating efficiency

The S3 AWS Airbar creates a more even flow of material through the feeder-house by eliminating waste-material build up, increasing cutting and feeding efficiency, reducing knife and internal component wear and operating time.
