Industrial Diesel Mobile Air Compressor – Technical Engineering Specifications

Product Series Overview

Our diesel mobile air compressor series encompasses a comprehensive range of portable, self-contained compressed air systems engineered for demanding industrial, construction, and mining applications. Available from 100 to 900 CFM with pressures to 150 PSI, these units combine proven compressor technology, industrial diesel power, and rugged mobile platforms to deliver reliable compressed air anywhere it’s needed.

Compressor Technology Options

Rotary Screw Compressors (185–900 CFM)

For continuous-duty applications requiring high volume and pulse-free air, our rotary screw compressors represent the optimal choice:

Compressor Air End:

• Precision-machined rotors with asymmetric profile for maximum efficiency

• Heavy-duty tapered roller bearings for extended life

• Two-stage air filtration standard

• Direct-drive or gear-drive configurations available

• Discharge temperatures: 15–25°F above ambient (with aftercooler)

Lubrication System:

• Integral oil sump with large capacity

• Full-flow oil filtration (3-micron nominal)

• Oil injection cooling optimizes compression efficiency

• Multi-pass oil separation ensures <3 ppm oil carryover

• Sight glass and dipstick for easy level checking

• Control switches: Start/stop, manual/auto mode, pressure adjustment

• Indicator lights: Power on, low oil pressure, high coolant temp, air filter restriction

• Emergency stop button

Optional PLC Control:

• Touchscreen interface with graphical display

• Automatic start/stop based on system pressure

• Load-sensing engine speed control for fuel optimization

• Fault logging with plain-language diagnostics

• Remote monitoring via CANbus or telematics
