Product Overview
The Sullair ST15 15 kW (20 HP) stationary compressor is engineered to provide 2280 LPM of consistent airflow for industrial pneumatic systems and assembly environments. Measuring 998 x 618 x 1035 mm, this metal-enclosed unit utilizes a direct-drive mechanism to ensure the oil-injected rotary screw pump operates efficiently at 8 bar (2.28 m³/min) or 10 bar (2.05 m³/min). Its 73 dB(A) noise level and integrated anti-vibration mounts allow for floor-mounted installation within workshops without exceeding acoustic safety thresholds. The 365 kg chassis houses a premium efficient TEFC motor compatible with 208–230/460 V 3-phase power supplies, eliminating the need for complex rewiring in most industrial settings. Users monitor performance via a digital display and smart controller that provides real-time alarm indications and self-diagnostics to maintain its continuous run capability throughout high-demand shifts.

Engineering Analysis
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.
