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