Product Description
AIRERA 18.5kW VSD Series: Precision, Purity, and Performance

    Elevate your industrial capabilities with the AIRERA 18.5kW VSD Direct-Driven Oil-Free Air Compressor. This powerhouse is the ideal solution for large-scale operations requiring 100% sterile, oil-free air. By integrating Variable Speed Drive (VSD) technology, the system intelligently adapts to your fluctuating air demand, eliminating idle energy waste and reducing electricity costs by up to 35%.

   The Direct-Driven architecture ensures maximum torque transfer without the energy loss or maintenance hassles of belts. Coupled with a high-capacity Air Cooling system, it maintains peak efficiency and thermal stability even during 24/7 continuous operation. AIRERA delivers the reliability and ISO Class 0 air quality essential for food processing and precision manufacturing.

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.

  • 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.

  • Water Cooler

        The plates are made of special 304L stainless steel, offering corrosion resistance and high heat transfer efficiency. This reduces pressure and temperature differentials, ensuring the system operates under near-isothermal compression. The system features a compact design, requires less cooling water, minimizes pressure loss, enhances durability, and is easy to clean and maintain.

AIRERA 18.5kW Screw Air Compressor: Frequently Asked Questions (FAQ)
What is the long-term Return on Investment (ROI) of a VSD unit compared to a fixed-speed model?
Although the initial purchase cost of a VSD machine is slightly higher, the energy savings and lower maintenance frequency typically allow you to recoup the price difference within 12 to 18 months.
What is the maintenance frequency for this model?
Extremely low. With no lubrication system, there’s no need for oil or oil filter changes. Maintenance is limited to replacing the air intake filter every 2,000–3,000 hours and periodically cleaning the cooler. This "low-maintenance" nature significantly cuts labor costs on industrial sites.
How does the direct-drive structure help extend the machine's lifespan?

Direct-drive achieves perfect coaxial alignment between the motor and air end, eliminating radial forces on bearings caused by belt tension. This significantly reduces the load on air-end bearings, extending the machine's mechanical lifespan by over 30% compared to belt-driven models while maintaining minimal vibration.
