CALT 19/21-21/18K Diesel Portable Compressor: Frequently Asked Questions (FAQ)
What specific projects benefit most from the AIRERA 19-21m³/min flow and 18-21bar pressure configuration?
This dual-regime configuration is optimized for deep-hole water well drilling, geothermal exploration, and mineral mining, where penetrating hard rock formations requires high impact energy. The 19-21m³/min flow rate effectively clears large volumes of heavy cuttings from deep holes, while the 18-21bar pressure provides the critical force needed to operate large down-the-hole (DTH) hammers efficiently, significantly accelerating project timelines.
How does AIRERA guarantee 24h stable running during continuous, heavy-load operations?
Continuous high-pressure discharge generates immense thermal energy. AIRERA eliminates this risk by pairing a premium heavy-duty diesel engine with an oversized, independent oil-and-water cooling system. This advanced thermal management keeps the operating temperature well within safe limits even in extreme ambient environments. Combined with a high-capacity fuel tank and multi-stage fuel filtration, the system supports non-stop 24h stable running under full load.
Can this diesel portable compressor be easily deployed in remote, off-road locations?

Yes, mobility is a core design feature. The compressor is engineered with an all-terrain move chassis, featuring a high-clearance suspension system and heavy-duty, puncture-resistant off-road tires. It includes a reinforced towing bar for site vehicles and a rigid single-point lifting ring for crane handling, allowing seamless transit and stable positioning over loose mud, jagged rocks, and steep mountain worksites.
