AIRERA 75kW Direct-Driven Oil-Free Water-Cooled Rotary Screw Compressor is the premier industrial choice for those seeking extreme air purity and superior energy efficiency. Featuring advanced 1:1 Direct-Drive technology, it eliminates energy losses associated with traditional belts or gears, ensuring precise and efficient power transmission. With its core oil-free compression technology, it delivers ISO Class 0 certified pure air, making it perfectly suited for stringent sectors like food, medical, and high-precision electronics. Combined with an optimized water-cooling system, it maintains stable thermal management even under extreme conditions, providing you with a low-noise, low-maintenance, and long-lasting green power experience.

Advantages of OGFD Air Screw Compressor:

  • Water cooler
        The plates are made of special 304L stainless steel, offering corrosion resistance and high thermal efficiency, which reduces pressure and temperature differentials and ensures 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.
  • 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 75kW Screw Air Compressor: Frequently Asked Questions (FAQ)
What are the advantages of Water-Cooling compared to air-cooling?
Water-cooling systems offer higher heat exchange efficiency and are unaffected by ambient temperature fluctuations. In high-temperature, dusty, or poorly ventilated environments, water cooling maintains a constant temperature more effectively, extending service life and ensuring stable air output 24/7.
What is the starting method for this 75kW rated power model?
AIRERA uses Star-Delta starting by default to reduce starting current impact, but Variable Frequency Drive (VFD) is also available as an option. The VFD version automatically adjusts motor speed based on actual air demand, offering even greater energy savings.
What is the main maintenance challenge for the water-cooling system in the long run?

The key lies in water quality management. We recommend using softened water to prevent scaling in the cooler. AIRERA’s coolers feature an easy-to-disassemble design, allowing users to clean scale regularly and ensure heat exchange efficiency remains at its peak.
