Description
AIRERA 75kW Oil-Free VSD Screw Compressor: Class 0 Pure Air & Ultimate Energy Efficiency

AIRERA 75kW VSD Direct-driven Water Cooling Oil-free Screw Compressor is the ultimate low-carbon power solution designed for high-standard industries. Certified with ISO Class 0 Oil-free standards, it ensures 100% pure compressed air, meeting the stringent requirements of pharmaceutical and electronic sectors. Featuring advanced VSD Direct-driven technology, it eliminates transmission losses and adjusts speed precisely to demand, boosting energy efficiency by up to 35%. Combined with a High-efficiency Water Cooling system, it guarantees stable operation even in extreme thermal conditions. AIRERA integrates exquisite craftsmanship with smart IoT to deliver a highly efficient, quiet, and reliable heart for your clean air supply.

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.

AIRERA 75kW Screw Air Compressor: Frequently Asked Questions (FAQ)
Will the VSD compressor overheat when running at low frequencies (low air demand)?
We have optimized the cooling system for all operating conditions. The air-cooling system of the AIRERA 7.5kW VP series provides high-efficiency heat exchange, ensuring the air end and electrical components remain at ideal temperatures even at low motor speeds.
What is the starting method for this 75kW rated power model?
AIRERA uses Star-Delta starting by default to reduce starting current impact, but Variable Frequency Drive (VFD) is also available as an option. The VFD version automatically adjusts motor speed based on actual air demand, offering even greater energy savings.
What is the main maintenance challenge for the water-cooling system in the long run?

The key lies in water quality management. We recommend using softened water to prevent scaling in the cooler. AIRERA’s coolers feature an easy-to-disassemble design, allowing users to clean scale regularly and ensure heat exchange efficiency remains at its peak.
