Dominate deep-hole drilling with the AIRERA Dual-Regime Diesel Portable Air Compressor. This premium powerhouse seamlessly switches between $27text{ bar}$ at $25text{ m}^3text{/min}$ and $18text{ bar}$ at $23text{ m}^3text{/min}$, delivering the ultimate flexibility for deep water well and geothermal drilling. Built on a reinforced all-terrain mobile chassis, it conquers rugged mining fields with absolute stability. Engineered with an advanced tropical cooling system, AIRERA guarantees 24-hour continuous, non-stop performance under extreme loads. Elevate your drilling efficiency to the next level.
The combination of gear transmission and coupling transmission has high efficiency, safety and reliability, and long service life.The helical gear transmission compensates the axial thrust by 30%, which further prolongs the life of the screw.The diesel engine (motor) is connected with the flange of the main screw machine to ensure the permanent alignment of the drive system.

Vibration reduction of main engine: shock absorber.Axle damping: damping rod.Double vibration reduction makes the machine run more smoothly.

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.
