CALT 30m³/min Flow, 8bar Pressure, All-terrain Move, 24h Stable Running Diesel Portable Compressor
Designed to anchor heavy-duty engineering operations, this AIRERA diesel portable compressor integrates a high-capacity 30m³/min volumetric flow with a calibrated 8bar operating pressure. The system utilizes a specialized all-terrain chassis engineered to maintain equipment stability and integrity across destabilized jobsites. Developed specifically for 24-hour operational continuity, its optimized thermal and power management systems eliminate thermal-related downtime, delivering the high-utilization efficiency demanded by global mining, tunneling, and infrastructure sectors.
Key Features:
- Cooling system
The cooler with large heat dissipation area is designed, which is suitable for harsh environments such as high temperature and high humidity in the field.Enlarged 30% cooling system to keep 25% cooling performance than old models for long-term working in the high-temp ambient. Environment. Unique fin and channel design, good heat dissipation, low pressure and easy cleaning.Low speed and low noise axial fan, low running noise; High temperature resistance and long service life.Horizontal exhaust to avoid hot air backflow and optimize cooling effect.

- Shock absorption system
Vibration reduction of main engine: shock absorber.Axle damping: damping rod.Double vibration reduction makes the machine run more smoothly.
- Air end
The rotor is made of German processing equipment-to ensure the dimensional accuracy of parts.The bearing adopts the world brand SKF--- prolong the service life.High-load-resistant design-working pressure can reach 1.6Mpa.

The all-terrain mobile design goes beyond high-clearance tires. It features a heavy-duty, torsion-resistant box chassis engineered through Finite Element Analysis (FEA), complemented by an independent torsion axle suspension and an adaptable steering towbar. This mechanical architecture effectively absorbs and dissipates the violent shocks and torsional stresses experienced during off-road towing, safeguarding the alignment of the internal engine and air end assembly.
