7.5KW VP Direct-driven Air Cooling Oil-free Air Compressor

AIRERA 7.5kW VP Series: The Future of Pure, Direct-Driven Power

Experience the pinnacle of compressed air technology with the AIRERA 7.5kW VP Series. Engineered for industries where purity is non-negotiable, this Direct-Driven, Oil-Free powerhouse eliminates the risks of oil contamination while maximizing energy efficiency. By removing belts and gears, our VP architecture reduces mechanical loss, ensuring a 100% duty cycle with minimal maintenance.The advanced Air Cooling system maintains optimal thermal stability even under heavy loads, safeguarding the precision-engineered components. Whether for medical, food processing, or high-tech manufacturing, AIRERA delivers a whisper-quiet, eco-friendly solution that slashes operational costs.

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.


  • Water Cooler

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

AIRERA 7.5kW Screw Air Compressor: Frequently Asked Questions (FAQ)
Does Variable Speed Drive (VSD) technology really reduce my electricity bills significantly?
Yes. Traditional compressors enter an "unloaded" idling state after reaching set pressure, wasting about 30% of energy. The AIRERA VSD series adjusts motor speed in real-time to perfectly match power output with actual air demand, eliminating idle waste and typically saving 25%-35% on energy costs.
Will the 7.5kW power output be too noisy for a small workshop?
Not at all. Thanks to the high-precision balance of the direct-drive transmission and AIRERA’s signature fully enclosed sound-dampening cabinet, the unit operates exceptionally smoothly. The noise level is significantly lower than traditional piston or belt-driven compressors, making it suitable for point-of-use installation without a dedicated machine room.
Is the daily maintenance for this machine complicated?

On the contrary, it is very simple. Because there is no oil system—meaning no oil changes, oil filters, or oil separators—and the direct-drive structure eliminates belt tensioning, maintenance is minimal. Users only need to periodically clean or replace the air intake filter and keep the cooler clean, saving substantial labor and consumable costs.
