In applications where duty cycles average 10 percent or more, or air pressures are above 862 kPa [125 psi], use a discharge line with a minimum inside diameter of 19 mm [0.75 in] to prevent carbon buildup. Examples of these applications are as follows:

  • Refuse trucks
  • Pickup trucks
  • Delivery trucks
  • Transit buses
  • Equipment with high accessory air usage.
