Product Overview
The Sullair 780VH is a specialized portable power unit designed to meet the high-pressure demands of large construction projects and mining operations. This model utilizes a direct-drive oil-injected rotary screw pump to generate 780 cfm of air at 24.1 bar, ensuring constant airflow for heavy air tools. The 6200 kg chassis is protected by a powder-coated industrial enclosure and includes a 700 L fuel tank to maintain the 216 kW Cummins engine over long shifts. Safety is prioritized through a 24 V control system that monitors for thermal protection and low oil shutdown, while the moisture separator ensures air quality. The weather-proof instrument panel houses a luxury dashboard with a smart controller that provides real-time alarm indications and self-diagnostics for the 780 cfm output.

Engineering Analysis
Engineering the 780VH around the Cummins QSM11-290 engine allows Sullair to achieve 216 kW of power to drive the rotary screw air end without efficiency loss through a direct-drive configuration. The 24.1 bar pressure capability is essential for deep-hole drilling where backpressure must be overcome, a task supported by the 22.1 m³/min free air delivery rate. With a dry weight of 6200 kg, the machine uses anti-vibration mounts to isolate the 1800 rpm motor vibrations from the heavy-duty enclosure. Noise insulation reduces the operational footprint to 81 dB(A), making it suitable for sites with strict environmental controls. The inclusion of a 24 V electrical system ensures that the smart controller can manage the self-diagnostics and overpressure protection valves with high precision, while the 700 L fuel tank is sized to match the fuel consumption rate of a 290 HP motor under continuous load.
