The 103-56459 A/C compressor is designed for heavy-duty mobile HVAC systems that require steady cooling during continuous operation. It uses the proven TM-16HD compressor platform, which supports dependable refrigerant flow in demanding applications.
Because this compressor uses a direct-mount configuration, it installs easily into compatible OEM brackets. In addition, the horizontal O-ring fitting layout simplifies hose routing and helps reduce leak points. As a result, installation time decreases while long-term reliability improves.
The 103-56459 operates on a 24-volt electrical system and uses a PV8 clutch with a 119 mm diameter. Therefore, it delivers smooth belt engagement and stable power transfer during extended duty cycles.
This unit ships with the specified 180 cc oil charge and is designed for R134a refrigerant systems. Furthermore, its OEM Valeo design makes it a dependable replacement option across multiple heavy-duty platforms.
