Description
AIRERA 90kW Oil-Free VSD Compressor: Zero Contamination & Intelligent Energy Management

AIRERA 90kW VSD Direct-driven Water Cooling Oil-free Screw Compressor is a premier power solution engineered for zero-emission and high-efficiency modern manufacturing. Strictly adhering to ISO Class 0 Oil-free standards, it ensures a clean production environment, safeguarding the critical processes of pharmaceutical and food industries. With advanced VSD Direct-driven technology, the system adjusts output in real-time, significantly optimizing start-up energy and reducing electricity costs by over 35%. Combined with an industrial-grade water cooling structure and smart IoT control, it delivers consistent, dry, and pure air pressure even under continuous heavy-duty cycles, helping you achieve a breakthrough in both green production and cost management.

Advantages of OGFD Air Screw Compressor:

  • Constant Voltage and Power Saving
The pressure comparison shown in the figure is in the operation of standard air compressor and the VFD air compressor. In standard air compressor, the loading and unloading is frequently changed between the sufficient pressure and pressure more than 1.5bar, which costs 10.5% of power consumption(more 7% of power is consumed when each 1bar is increased )compare with the inverter control. In addition, 45% of idle power energy is consumed in standby status of zero air supply in the unloading. Therefore, air supply inconstant pressure is not only very low power consumption, but also avoids the reduction of service life of the unit caused by the control of loading and unloading and the adverse factors of unstable pressure brought to the production of the enterprise.

90KW VSD Direct-driven Water Cooling Oil-free Rotary Screw Compressor
  • Relief valve

The independently designed unloading valve (Patent No.: ZL200520058468.2), specifically engineered for vortex characteristics, enables fully sealed operation in screw compressors, ensuring stepless air delivery from 0 to 100%.


90KW VSD Direct-driven Water Cooling Oil-free Rotary Screw Compressor

  • Patented High-Efficiency Compressor Block

The compressor block is constructed from 304L stainless steel,featuring a world-class sealing system that integrates mechanical seals,an air curtain chamber, labyrinth seals, and a bypass channel into a single unit.

AIRERA 90kW Screw Air Compressor: Frequently Asked Questions (FAQ)
Will the addition of an inverter make the system more prone to failure?
Not at all. AIRERA utilizes high-performance industrial inverters with self-protection features against overvoltage and overheating. By enabling a "Soft Start," the starting current rises smoothly, avoiding electrical and mechanical shocks to the grid and components, which actually extends equipment life.
How is low noise and vibration ensured during 90kW high-power operation?
AIRERA utilizes a precision-balanced direct-drive architecture, eliminating vibration-prone gear sets. Combined with thickened soundproof enclosures and heavy-duty anti-vibration bases, noise levels are kept at industry-leading lows even during full-speed operation.
Can the 90kW water-cooling system support 24-hour continuous full-load operation?

Yes. The system is designed for heavy-duty use, featuring shell-and-tube coolers with large heat exchange surface areas. Even in high ambient temperatures, it maintains precise thermal control via water flow adjustment, ensuring no overheating shutdowns.
