BT5-4435 24V Heavy-Duty A/C Compressor – SD7H15HD-FLX7, Ear Mount, 2-Groove 132mm

Overview

The BT5-4435 SD7H15HD-FLX7 compressor is engineered for 24V heavy-duty mobile HVAC systems, particularly in farm, construction, and off-road equipment. Because of its ear 8-long mounting design, the compressor provides improved stability in high-vibration applications. At the same time, the 2-groove, 132 mm clutch supports traditional dual 1/2-inch V-belt systems commonly used on diesel-powered machinery.

Additionally, this unit uses a GV-style cylinder head with rear universal O-ring FLX-7 pad fittings, which allows for flexible hose routing across a wide range of OEM and aftermarket installations. As a result, it integrates easily into both new builds and replacement systems. Furthermore, clockwise rotation and a 1-wire Packard electrical interface with integrated diode protection ensure compatibility with standard heavy-duty compressor control circuits using R134a refrigerant.
