Applications:
Used on heavy-duty commercial vehicles requiring a TF-400 water-cooled pulley-drive compressor with 6-hole base mount and left-side inlet and outlet ports. The compressor supplies compressed air for brake and auxiliary pneumatic systems and is typically replaced when air output decreases, leakage occurs, or internal wear affects system recharge.
