Applications:
Used on heavy-duty truck and commercial vehicle air brake systems requiring a TF-500 pulley drive compressor with 4-hole base mounting, right-side inlet/outlet orientation, external shaft, and top/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.
