Product Overview
The Sullair 320 centers its performance on a 320 cfm (9.06 m³/min) free air delivery rate, optimized for heavy-duty pneumatic tools used in construction and rental fleets. Operating at a maximum pressure of 6.9 bar, the 1288 kg unit is housed in a galvanneal sheet metal enclosure with a durable powder coat finish to withstand job site exposure. Power is generated by a 58 kW (78 hp) diesel engine coupled via direct drive to the oil-injected rotary screw pump, ensuring efficient energy transfer without the maintenance of belts. This portable towable trailer configuration includes a moisture separator and a weather-proof instrument panel, allowing for reliable operation in civil works or coating projects. With a continuous duty cycle and protective shutdown switches, the 320 model maintains uptime for air-intensive tools across multi-shift industrial applications.

Engineering Analysis
The 58 kW direct-drive configuration eliminates belt-slippage losses, directing torque to the rotary screw pump to sustain the 320 cfm output. By utilizing oil-injected lubrication, the Sullair 320 manages thermal loads effectively during 24/7 continuous duty cycles, which is critical for high-volume blasting and coating tasks. The 6.9 bar pressure rating is specifically calibrated for standard air tools, while the 9060 LPM airflow provides the volume required for large-diameter pneumatic piping. Weighing 1288 kg (wet), the unit's wide track and wheel support are balanced for stable towing at highway speeds, and the clam-shell design allows 100% access to internal components for servicing. Safety is prioritized through a low oil shutdown system and thermal protection, preventing damage to the air end, which is backed by a 10,000-hour warranty.
