BT5-4609 12V Super Heavy-Duty A/C Compressor – SD7H15-SHD, Ear Mount, 2-Groove 152mm, MD Head

Description

Overview

The BT5-4609 SD7H15-SHD compressor is designed for 12-volt mobile air conditioning systems commonly used in agricultural, construction, and off-road equipment. Because of its ear 8-long mounting design, the compressor provides enhanced stability in high-vibration environments. At the same time, the dual 1/2-inch belt drive and 152 mm clutch support higher belt loads and improved power transfer.

Additionally, this unit uses an MD-style cylinder head with horizontal Tube-O fittings, allowing for clean hose routing in both OEM and aftermarket installations. As a result, it integrates easily into replacement and retrofit systems. Furthermore, its clockwise rotation and simple electrical interface ensure compatibility with standard heavy-duty A/C control systems.
