Description
AIRERA 18.5kW Direct-Driven Air-Cooling Oil-Free Industrial Air Compressor: Pure Air, High-Efficiency Drive

This 18.5kW industrial-grade oil-free air compressor perfectly integrates AIRERA’s premium manufacturing standards with cutting-edge technology, specifically designed for industries with stringent air purity requirements such as food processing, and precision electronics. Featuring a high-efficiency direct-drive system, it eliminates the energy loss associated with belt drives, ensuring exceptionally stable and long-lasting power output. The core oil-free compression technology, paired with an advanced air-cooling solution, guarantees 100% clean, oil-free air while significantly simplifying maintenance procedures and reducing operating costs. Its intelligent control system precisely matches industrial load demands, delivering superior energy efficiency and low-noise operation to help enterprises achieve the dual goals of green production and high-capacity output, making it a reliable partner for high-quality production environments.

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.
18.5KW Direct-driven Air Cooling Oil-free Industrial Air Compressor
  • Imported softeners

Used to remove scale from cooling water and effectively prevent the precipitation of impurities, ensuring unobstructed compressor piping. It has a maximum service life of 3 years.


18.5KW Direct-driven Air Cooling Oil-free Industrial Air Compressor

  • Unloading Valve

The independently designed unloading valve (Patent No.: ZL200520058468.2) is specifically engineered for vortex characteristics, enabling the screw compressor to achieve a fully sealed operation with 0–100% capacity, ensuring stepless air delivery.

AIRERA 18.5kW Screw Air Compressor: Frequently Asked Questions (FAQ)
What are the advantages of a Direct-Driven system over a belt-driven one?
The direct-drive design connects the motor and the air end via a high-precision coupling, achieving a transmission efficiency of up to 99.9%. Unlike belt-driven models, it eliminates energy loss from slippage and wear, reduces the number of consumable parts, and ensures quieter operation with lower vibration, significantly cutting long-term maintenance costs.
How does this equipment perform in terms of energy efficiency?
Beyond the high efficiency of the direct-drive system, this model is equipped with the AIRERA Intelligent Control System. It monitors pressure demand in real-time to prevent energy waste caused by frequent loading and unloading. For even higher efficiency, we offer VSD (Variable Speed Drive) versions that adjust motor speed to match actual air consumption, potentially saving an additional 30% or more in energy costs.
Is the maintenance for an oil-free compressor expensive?

On the contrary, it can be more cost-effective over time. Since the system is completely oil-free, you eliminate the need for expensive oil filters, oil-air separators, and the oil itself. Maintenance is primarily focused on the air intake filters. This not only reduces the cost of spare parts but also removes the legal and environmental expenses associated with disposing of waste oil.
