Applications:
Used on Class 8 and vocational truck applications requiring a TF-400 pulley-drive compressor with right-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.
