Applications:
Used on water-cooled TF-500 pulley-driven air brake systems requiring a 4-hole base mount, right-side inlet/outlet orientation, external shaft, and flange discharge configuration. The compressor supplies air for service brake and auxiliary pneumatic systems and is typically replaced due to reduced air output, oil carryover, overheating, or internal wear.
