Question – Where is the Air Dryer located on your vehicle? 11:04
Most drivers’ manuals indicate that the air dryer is optional; however, this air brake components have been an integral part of a truck or bus’ air brake system for more than a quarter century.
The air brake system’s air dryer is located between the compressor and the first air tank. On older systems it is located between the compressor and the “wet” (supply) tank. On newer ADIS (Air Dryer Integrated Systems) the air dryer is located between the compressor and the primary and secondary air tanks (reservoirs).
There are two indicators of ADIS systems:
1) The governor is located within close physical proximity to the air dryer – often right beside the air dryer;
2) When building air pressure, an ADIS system will build either the secondary or primary sub-system to approximately 100 psi (pounds per square inch) and then build the other system.
When both systems attain approximately 100psi, both systems will build to maximum system pressure. When the air brake system attains maximum pressure the air dryer will purge, discharge or spit. The air dryer is the first indicator that the air brake system is at maximum pressure. Yet, when conducting a pre-trip inspection, a driver must confirm by the air gauges on the dash that yes, in fact, the system is at maximum pressure.
