90KW Belt driven air-cooling oil inject screw compressor
As the power cornerstone for heavy-duty industrial lines, the AIRERA 90kW oil-injected screw compressor integrates high-volume displacement with the flexible advantages of belt transmission. Engineered for rigorous 0.8-1.3MPa conditions, this model features a low-speed, large-rotor air-end paired with a multi-vee reinforced synchronous drive system. This configuration significantly suppresses mechanical vibration during high-power operation while shielding the powertrain from torque impacts during frequent starts. To master the immense thermal energy generated by the 120HP class, we’ve implemented a customized redundant cooling matrix and patented oil temperature monitoring, ensuring a steady flow of powerful, dry compressed air even in 45°C environments. This represents AIRERA’s commitment to high-power reliability—a "low-maintenance, high-output" energy expert tailored for your production line.

This model is designed to be maintenance-friendly. The side panels provide direct access to the belts, oil separators, and filters, making replacements straightforward. Typically, the routine maintenance interval is between 2,000 and 3,000 hours, depending on the working environment. Because the belt-drive structure is uncomplicated, onsite technicians can handle basic servicing, reducing reliance on third-party engineers and lowering labor costs.
