Applications:
Used on Caterpillar engine, wheel loader, motor grader, petroleum packaging, skid mounted pumper, earthmoving compactor, and generator applications requiring a TF-550 compressor with 31.5° flange mounting and top-mounted inlet/outlet 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.
