CALT-12.5/14K Diesel Portable Compressor: Frequently Asked Questions (FAQ)
Under long-term 14bar high-pressure operation, how are the oil-gas separation system and air purity guaranteed?
High-pressure operation significantly accelerates oil atomization. AIRERA has engineered a customized, heavy-duty three-stage oil-gas separation system specifically for 14bar systems. By combining centrifugal force, gravity, and a high-efficiency oil separator element, the oil carryover in the discharge air is strictly kept below 3ppm, even under continuous high pressure. This protects your downstream high-pressure drilling tools and reduces oil consumption.
For large-scale projects, how does this 12.5m³/min model address heavy fuel consumption in the field?
While 14bar operations are notoriously fuel-intensive, AIRERA tackles this with an original electronic common-rail diesel engine paired with our self-developed intelligent volume control valve. When the downstream drill rig pauses or air demand drops, the system synchronizes and lowers the engine speed and intake valve openness within milliseconds. This smart "air-on-demand" logic delivers over 18% fuel savings compared to conventional fixed-speed high-pressure portable units.
Are the high-pressure hose connections and on-site operation complex? Can a new operator learn it quickly?

AIRERA focuses on user-centric engineering. Despite being a heavy-duty 14bar machine, it features standard quick-connect high-pressure discharge valves equipped with safety whip-checks to prevent accidental hose decoupling. The control panel utilizes intuitive iconography and supports one-touch start/stop in both Chinese and English, complete with a fully automated self-diagnostic system. A new operator can safely and proficiently run the entire unit after a simple 10-minute training session.
