15HP VSD Direct-driven Air Cooling Oil-free Industrial Air Compressor
Maximize your operational efficiency with the AIRERA 15HP (11kW) VSD Direct-Driven Oil-Free Air Compressor. This industrial-grade powerhouse is designed for sectors where 100% air purity is critical. By combining Variable Speed Drive (VSD) technology with a Direct-Drive mechanism, it eliminates transmission loss and prevents energy waste during low-demand periods, reducing power consumption by up to 35%.
The integrated Air Cooling system ensures stable performance in high-load environments without the need for complex water infrastructure. With its Oil-Free design, the AIRERA 15HP VSD delivers ISO Class 0 certified air, protecting your downstream equipment and ensuring zero contamination in sensitive processes like food production or electronics.
Advantages of OGFD Air Screw Compressor:
- Constant Voltage and Power Saving
- 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.
- 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.
