AIRERA 50HP VSD Series: Engineering Excellence in Pure Air Technology

   The AIRERA 50HP (37kW) VSD Direct-Driven Oil-Free Rotary Screw Compressor is a high-performance solution designed for large-scale industrial environments where air purity and energy efficiency are paramount. By integrating advanced Variable Speed Drive (VSD) technology with a Direct-Drive mechanism, this system intelligently adjusts its output to match your real-time demand, eliminating idle energy waste and slashing power costs.

   Its Oil-Free Rotary Screw design guarantees ISO Class 0 certified air, ensuring zero risk of contamination for sensitive processes. Supported by a heavy-duty Air Cooling system, the AIRERA 50HP model provides consistent thermal management and exceptional reliability for 24/7 operations in the healthcare sector, food processing, and high-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.

  • Water filter

        The housing is made of stainless steel, offering high filtration precision and a long service life, ensuring the system remains clean and free of impurities.


  • 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 37kW 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 does AIRERA ensure the durability of the rotors without oil lubrication?
Our rotors feature a special aerospace-grade coating and precision clearance design. This prevents metal-to-metal contact and corrosion, ensuring the screw hosts maintain high efficiency and a long service life even without oil.
What about the noise level of a 50HP direct-driven unit?

Thanks to the direct-drive precision and our fully enclosed sound-dampening cabinet, the noise level is significantly lower than gear-driven competitors. It creates a much more comfortable and safer working environment for your staff.
