High Light 30m³/min diesel portable compressor8bar pressure oil free screw compressorall-terrain portable air compressor
AIRERA Engineered Mobile Air Infrastructure: 30m³/min, 8bar High-Volume Diesel System

    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.

CALT CALT-30/8K Diesel Portable Compressor: Frequently Asked Questions (FAQ)
Why is the combination of 30m³/min flow and 8bar pressure considered an optimal specification for large-scale engineering?
The combination of a 30m³/min high free air delivery (FAD) and a stable 8bar operating pressure is perfectly calibrated for high-volume, mid-pressure industrial applications. It is highly effective for large-scale abrasive blasting, bridge anti-corrosion coating, railway construction blow-downs, and simultaneously powering multiple heavy-duty rock drills. This configuration ensures that even with long-distance piping, end-line pneumatic tools receive maximum volumetric flow without critical pressure drops.
Under 24-hour continuous heavy-duty operation, how does AIRERA prevent thermal oil emulsification or carbonization in the air end?
Sustained 24/7 non-stop running heavily taxes the lubrication chemistry. AIRERA utilizes a proprietary high-efficiency oil-gas separation system paired with a precision thermostatic valve. Combined with an oversized, high-temperature-differential plate-fin cooler, the system strictly maintains the compressor fluid within its optimal viscosity window. This eliminates both moisture condensation (preventing emulsification) and excessive thermal buildup (preventing carbonization), guaranteeing long-term operational continuity.
How is the chassis structurally reinforced to endure rugged mine sites or roadless topographies?

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.
