St15 Specifications, Features & Compatibility Guide

The ST15's direct-drive configuration is technically superior because it transfers 15 kW of motor power directly to the screw rotors, achieving higher energy efficiency than belt-driven models. By delivering 80.1 CFM at 9 bar, the unit provides the necessary volume for heavy-duty tools like grinders and impact wrenches that demand a continuous industrial duty cycle. The integration of a moisture separator and a manual condensate drain ensures that the 2.28 m³/min of air delivered is stripped of bulk liquid before reaching downstream regulators or spray guns. Safety is managed through low-oil shutdown sensors and thermal protection circuits that trigger the auto-cutoff if internal temperatures deviate from 60 Hz operational norms. The 5-year Emerald Warranty reflects the engineering confidence in the 365 kg powder-coated metal enclosure and the internal pressure relief valve system designed for maximum pressures up to 12 bar.
