Product Description
AIRERA 250kW VSD Oil-Free Compressor: Leading the Way in Pure Power and Smart Energy Savings
Designed for the apex of industrial performance, the AIRERA 250kW oil-free rotary screw compressor delivers 100% Class 0 certified pure, contaminant-free air, safeguarding sensitive operations in medical, food processing, and semiconductor manufacturing. By combining advanced VSD technology with an integrated direct-driven setup, this powerful unit eliminates transmission losses and slashes energy consumption by up to 35%, while its heavy-duty water-cooling system ensures exceptional thermal stability and uninterrupted reliability under continuous full-load conditions, offering a green, highly efficient, and low-maintenance power solution for forward-thinking enterprises.
Advantages of OGFD Air Screw Compressor:
- Constant Voltage and Power Saving
- Relief valve
The independently designed unloading valve (Patent No.: ZL200520058468.2), specifically engineered for vortex characteristics, enables fully sealed operation in screw compressors, ensuring stepless air delivery from 0 to 100%.
- 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.

AIRERA 250kW Screw Air Compressor: Frequently Asked Questions (FAQ)
Can the VSD compressor maintain stable pressure if my factory's air demand fluctuates?
This is the primary strength of VSD units. It responds to pressure changes in milliseconds, keeping fluctuations within ±0.01MPa. Constant pressure significantly improves the yield rate in precision manufacturing, such as food packaging and electronics assembly.
What are the core advantages of the 250kW model in food processing and electronics manufacturing?
Both industries have rigorous air purity requirements. AIRERA's 100% oil-free technology eliminates the risk of product oil contamination at the source, preventing costly recalls, while its pressure stability ensures the precision of sensitive pneumatic components and automated production lines.
Does the 250kW model have a high impact on the power grid during startup?
The model offers optional VFD soft-start technology, ensuring a smooth startup current without impacting the facility's power grid. This protects electrical components and avoids peak-demand penalties or voltage fluctuations caused by high startup inrush.
