The air system consists of an engine-driven air compressor (1) and eight air reservoirs (2) through (9). Air is drawn from the
engine air intake and routed to the air compressor (1). Pressurized air flows from the air compressor through an aftercooler, a
coalescing filter, and through an air dryer (10) where the air is cooled and the moisture/oil is removed. Moisture not removed
by the air dryer will condense in the air reservoir. System air pressure is 119 psi (820 kPa). The air system includes the
necessary valves and air lines to control the vehicles's air-operated devices. The air compressor supplies 15 cfm at 119 psi
(3.25 m3/min. at 820 kPa). Air pressure in this system is shown by the red needle on the DUAL BRAKE PRESSURE gauge
inside the cab.
