5.5KW VSD air-cooling oil inject screw compressor
Smart Power, High Efficiency — Engineered for Precision and Performance
The AIRERA 5.5kW Series combines unrivaled energy efficiency with rock-solid reliability. Specifically designed as a primary power source for small-to-medium workshops, automotive services, and precision manufacturing, this model leverages advanced Variable Speed Drive (VSD) technology. By automatically adjusting motor speed to match your real-time air demand, it slashes energy consumption by over 30% compared to fixed-speed alternatives, significantly lowering your operational costs.
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.

The more efficient SF 1.2 IP55 VSD motor complies with IE5 and MEPS standards and meets the national Class 1 energy efficiency standards.

The core differences are energy savings and pressure stability.
-
Energy Savings: A fixed-speed compressor enters an "unloading" state when demand is met, where the motor continues to spin and waste electricity. The AIRERA VSD (Variable Speed Drive) model automatically adjusts the motor speed to match your actual air demand. You only pay for the air you use, typically reducing electricity bills by 30%–35%.
-
Stable Pressure: VSD technology keeps discharge pressure fluctuations within $pm 0.01text{ MPa}$, which is crucial for protecting sensitive pneumatic tools and ensuring consistent product quality in precision manufacturing.
Screw compressors are far more durable than piston types and require less frequent maintenance:
-
Initial Service: Change the oil and oil filter after the first 500 hours of operation.
-
Routine Service: Standard maintenance (changing air filter, oil filter, oil-gas separator, and lubricant) is typically required every 2,000 to 3,000 hours.
-
Smart Alerts: The integrated control panel tracks running hours and provides automated alerts when maintenance is due.
This is a highly versatile "golden power" size, ideal for:
-
Small-to-medium CNC machining centers and laser cutting assistance.
-
Automotive repair shops and professional spray painting booths.
-
Small-scale food packaging or woodworking workshops.
-
Laboratory air supply and precision instrument support.
