BT5-45084 12V TM15 A/C Compressor – Direct Mount, 8-Groove 125mm, C Head

Description

Overview

The BT5-45084 TM15 compressor is engineered for 12-volt mobile air conditioning systems that require a direct-mount design paired with a serpentine belt drive. Because of this configuration, the compressor provides improved alignment and reduced vibration compared to traditional ear-mount designs. At the same time, the 8-groove, 125 mm clutch supports stable belt engagement on high-accessory engines.

Additionally, this unit uses a C-style head with horizontal O-ring pad ports, which allows for clean hose routing in both OEM and aftermarket installations. As a result, it integrates easily into replacement and retrofit systems. Furthermore, its CW / CCW rotation capability simplifies application matching across multiple engine layouts.
