Sullair 375H T4 – Tow-Behind Portable Diesel Air Compressor

Sullair 375H T4 | 375 CFM at 90 PSI Industrial Delivery Analysis

The Sullair 375H T4 is a massive tow-behind portable diesel compressor engineered for heavy-duty infrastructure and large-scale industrial projects. Powered by a 115 HP Caterpillar engine, this unit is optimized for volumetric efficiency to deliver an immense 375 CFM airflow at 90 PSI. It serves as a critical mobile power plant for utility crews and civil contractors who require a 100 percent duty cycle for operating heavy pneumatic breakers and industrial sandblasting equipment in the most demanding outdoor environments.

The rotary screw air-end is designed for exceptional thermal stability, ensuring efficient power transfer and sustained performance during continuous operation in harsh field conditions. Due to the high-demand nature of diesel rotary systems, regular manual oversight of fluid levels and moisture discharge is required to protect the precision air-end and maintain long-term reliability. The integrated low oil protection system provides a critical automated safeguard for the CAT engine, while the 65-gallon fuel capacity supports extended operational shifts without frequent refueling.
