132kW VSD Direct-driven Water Cooling Oil-free Rotary Screw Compressor | AIRERA High-Efficiency Industrial Solutions
AIRERA 132kW VSD direct-driven water-cooled oil-free rotary screw compressor delivers 100% certified oil-free compressed air, making it an ideal choice for high-precision environments such as medical, healthcare, and food processing industries where air purity is critical. Engineered with advanced permanent magnet variable frequency technology and a direct-drive structure, this unit eliminates energy loss from gears or belts while the robust water-cooling system ensures stable, continuous operation even in demanding high-temperature conditions. By integrating AIRERA’s signature reliability with E-E-A-T professional standards, this compressor provides a sustainable, low-maintenance, and ultra-efficient solution that significantly reduces long-term operational costs and environmental impact for global industrial users.
Advantages of OGFD Air Screw Compressor:
- Constant Voltage and Power Saving
The pressure comparison shown in the figure is in the operation of standard air compressor and the VFD air compressor. In standard air compressor, the loading and unloading is frequently changed between the sufficient pressure and pressure more than 1.5bar, which costs 10.5% of power consumption(more 7% of power is consumed when each 1bar is increased )compare with the inverter control. In addition, 45% of idle power energy is consumed in standby status of zero air supply in the unloading. Therefore, air supply inconstant pressure is not only very low power consumption, but also avoids the reduction of service life of the unit caused by the control of loading and unloading and the adverse factors of unstable pressure brought to the production of the enterprise.

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%.

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.

AIRERA 132kW 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.
How does the "Water-Cooling System" perform under extreme heavy-load conditions?
The AIRERA 132kW utilizes thickened copper-tube heat exchangers with multi-layer anti-corrosion treatments. Even under 100% full-load operation 24/7, its efficient heat exchange surface area rapidly dissipates heat, ensuring air-end bearings and seals work under low temperature rises to extend the overall service life.
Why is "Oil-Free" more emphasized for high-power equipment like the 132kW model?
In ultra-large-scale production (such as medical or semiconductors), a tiny amount of oil contamination can lead to the scrapping of entire product batches. As the core power source, the Class 0 oil-free guarantee of the 132kW unit is the final line of defense against massive economic losses.
