55KW,75HP PM VSD Direct driven oil inject screw compressor

AIRERA 55kW/75HP IE5 PM-VSD Direct Driven Series: Zero-Loss Transmission, Peak Industrial Performance

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.

Advantages of AGCD VSD Oil-Inject Air Screw Compressor
  • 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.


  • Specialized Oversized Inlet Valve

· Normally closed, oversized bore, ultra-low pressure drop;

· Low failure rate, long service life

AIRERA 55kW VP Screw Air Compressor: Frequently Asked Questions (FAQ)
For a high-power unit like 55kW, can VSD technology really recover the initial investment?
Yes, and quite rapidly. A 55kW unit is a major energy consumer; its annual electricity cost often exceeds the purchase price of the machine. AIRERA’s VSD technology dynamically adjusts power based on demand. If your air consumption fluctuates, you can save approximately 35,000 to 60,000 kWh per year compared to a fixed-speed unit. Typically, the energy savings pay back the VSD premium within 12-18 months.
Are there any special installation requirements for the 55kW Direct Drive model?

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.

Is the flexible coupling in the direct drive unit durable? How often should it be checked?
We use high-strength, fatigue-resistant synthetic rubber couplings reinforced specifically for VSD’s frequent speed adjustments and starts/stops. It acts as an excellent buffer to protect motor bearings. Typically, the coupling only requires a routine inspection every 8,000 to 12,000 hours, lasting far longer than high-wear belts.
