-
Industry-leading air host
The air compression chamber is completely separated from the oil chamber. The air side adopts a non-abrasive sealing system with a spring-loaded metal ring, and the lubricating oil side adopts a non-abrasive sealing system with a copper labyrinth seal. The two do not contact;
-
Advanced and reliable electronic control system
Large-size color LCD touch screen, with a good human-machine communication interface, the touch screen has anti-mistouch and sleep functions;Completely monitor various parameters of the machine, including voltage detection, three-phase unbalance detection, overvoltage, overtemperature, etc., without special supervision;configure the Internet of Things, you can check the operating status of the unit on the mobile phone.Independent air duct design, suitable for various working conditions.
- Independent air intake system
Independent air intake ensures that the intake air temperature is equal to the ambient temperature. Large-capacity air filter is used to achieve better filtering effect, lower intake pressure loss, and energy saving and high efficiency. Maintenance and replacement are more convenient.

When a single-stage compressor pushes for high pressure (e.g., above 1.0 MPa), an excessive pressure ratio leads to severe internal backflow leakage and overheating. AIRERA’s two-stage compression distributes the total pressure ratio across two pairs of rotors working in series, with inter-cooling in between. This significantly minimizes internal leakage and maximizes volumetric efficiency, delivering 10%–15% more air output than a single-stage model at the same power input. This drastically lowers the specific power consumption, saving you a massive amount on electricity bills in the long run.
Oil-injected screw technology is currently the most mature and cost-effective solution in the industry, as the oil provides exceptional sealing, lubrication, and cooling, which greatly extends the equipment lifespan. To ensure air quality, AIRERA is equipped with a high-efficiency 3-stage oil-gas separation system, keeping the residual oil mist content to an absolute minimum (typically $le 3text{ppm}$). If your applications require high-purity air (such as precision instruments or spray painting), simply adding our line filters and a refrigerated air dryer downstream will easily deliver ISO-certified, top-quality clean air.
