Tandem model as triple-passage design
Deublin has developed a number of hubmounted unions specifically designed to accommodate the passage of air between a vehicle’s stationary axles and its wheels. This allows tire pressure to be varied from inside the vehicle’s cab, and is already very popular in the logging industry and on military vehicles. The ability to vary the air pressure allows the driver to adjust pressure for the surface being traveled. Lower pressure with a broader footprint is suitable for soft terrain. Higher pressures and a smaller footprint is suitable for higher speed highway travel. Model 882, 2-passage union, Model 1115-000-001, Model 1102-025-001-004.
