CALT 21m³/min Flow, 13bar Pressure, All-terrain Move, 24h Stable Running Diesel Portable Compressor
Optimize subsurface and infrastructure workflows with AIRERA’s precision-engineered mobile pressure solution. Delivering a consistent 21m³/min volumetric flow optimized for 13bar high-pressure impact, this diesel-driven system guarantees maximum pneumatic tool velocity without line degradation. Its engineered all-terrain chassis architecture provides exceptional mechanical stability in remote regions, while the high-capacity fluid management system yields 24/7 uninterrupted running stability—the definitive standard in asset lifecycle and operational continuity.
- Diesel engine
In the intake system, exhaust gas turbocharging is adopted to improve the power performance.Meet the Euro II emission standards, high-performance oil pump, low fuel consumption.The overall structure is compact and the appearance is beautiful and generous.Covering the whole country's after-sales service network, users can get rapid and complete service.
- 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.

Our all-terrain chassis architecture is engineered via rigorous Finite Element Analysis (FEA) to simulate and neutralize torsional strains. Built with a high-resistance box steel framework, it deflects the multi-directional stresses induced by extreme cross-country towing. Furthermore, heavy-duty off-road tires paired with a premium independent suspension isolate the internal twin-screw air end and engine alignment from violent impact shocks, preserving overall asset structural integrity.
