BT5-4270 Heavy-Duty A/C Compressor – SD7H15, 24V, PV8

Description

The BT5-4270 A/C compressor is engineered for heavy-duty mobile air-conditioning systems that operate under sustained load. Because it uses the proven SD7H15 compressor platform, it delivers high displacement and consistent refrigerant flow in demanding environments.

In addition, this compressor features a direct-long mounting design, which helps maintain proper alignment and simplifies installation in compatible brackets. As a result, belt tracking remains stable while long-term reliability improves.

Furthermore, the PV8 rotor and clutch configuration supports smooth power transfer and efficient torque handling. Therefore, this compressor performs well in applications that demand higher airflow and continuous operation.

The BT5-4270 operates on a 24-volt electrical system and uses a single-wire male bullet connector, which keeps wiring simple and service-friendly across fleet and vocational equipment.
