When sourcing a runway sweeper, the most critical technical factor is the FOD (Foreign Object Debris) removal efficiency, which should ideally be above 98%. Buyers must evaluate the suction power (measured in Pascals) and the sweeping width, typically ranging from 2,500mm to 5,000mm for airport use. Additionally, ensure the vehicle is equipped with a high-performance auxiliary engine (e.g., Cummins or Deutz) to provide independent power to the vacuum system, ensuring consistent performance regardless of vehicle speed.
