55KW,75HP PM VSD Direct driven oil inject screw compressor
The AIRERA 55kW series is our flagship solution engineered for heavy-duty industrial environments that demand high reliability and rapid response. By perfectly integrating VSD (Variable Speed Drive) technology with a Direct Driven system, we have eliminated the efficiency bottlenecks of traditional transmission, delivering stable, high-quality compressed air at the lowest possible cost.
- Upgraded high-efficiency screw compressor heads for greater airflow
By selecting low-speed screw rotors and the most suitable motors, and pairing them with main units optimized for specific speeds, we ensure that each rotor operates at its optimal speed, achieving the best possible energy efficiency ratio.

With a wider frequency modulation range of 30–200 Hz, it is 15–35% more energy-efficient than most 300–100 Hz compressors on the market
Next-generation control system: We employ dual-inverter technology, retaining the original motor inverter features while also incorporating an inverter-controlled cooling fan for the main unit. This dual-inverter approach ensures the cooling system operates in a stable state, and the modular design facilitates easy maintenance.
PCB coating enhances environmental resistance; an excellent heat dissipation design allows operation at ambient temperatures up to 50°C. The system automatically adjusts the output rating based on temperature rise conditions to maintain the inverter’s sustained high-efficiency operation.

Mainly space and ventilation. Due to its high capacity, the unit generates significant heat. While AIRERA has optimized the internal cooling airflow, we recommend placement in a well-ventilated, independent compressor room. Notably, because the direct drive structure is highly compact, its footprint is actually smaller than many belt-driven units of the same power, saving valuable floor space.
