BT5-4326 Compressor – Sanden 7H15SPRHD 12V R134a, 180mm 8-Groove Clutch, WV Head

The BT5-4326 Sanden compressor is built on the 7H15SPRHD (Severe-Duty, Short-Mount, Reinforced) platform, designed for sustained operation in heavy-duty on-highway HVAC systems.

This compressor operates on 12 volts, uses R134a refrigerant, and features a 180mm PV8 serpentine clutch, providing increased surface area and torque capacity for high-accessory-load engines. The WV head design utilizes a rear pad O-ring configuration with Volvo offset (top-left, suction over discharge) to ensure proper hose routing and OE fitment on Mack and Volvo platforms.

A direct-short mounting configuration, long keyed shaft, and 2-wire Packard electrical connection make this unit a direct replacement for multiple Sanden, Mack, Volvo, and aftermarket references.
