TF-501 Compressor Design
The TF-501 compressor utilizes a two-cylinder reciprocating piston design operating through a single-stage compression process. With an airflow rating of approximately 12 cubic feet per minute at 1250 RPM, the compressor provides dependable air delivery for heavy-duty truck air brake systems.
The compressor uses a combined air and water cooling system to help maintain proper operating temperatures during extended operation. The unit is lubricated through the engine’s oil system and features threaded discharge ports for secure air system connections.
The flange-mounted engine-driven design is commonly used on Mack diesel engines found in highway tractors, vocational trucks, municipal fleet vehicles, and construction equipment.
