The AIRERA 250kW VSD Oil-Injected Screw Compressor is custom-engineered for extreme heavy-duty demands and high-pressure applications. Supporting a wide pressure adjustment range of 0.8–1.3MPa, this unit precisely matches diverse industrial requirements, from standard manufacturing to high-pressure blowing processes.
At its core, the AIRERA intelligent VSD system works in harmony with a low-speed, large-rotor air end. This ensures superior energy efficiency even under continuous high-pressure output, achieving comprehensive energy savings of over 35%. To manage the thermal demands of its massive 250kW capacity, the unit features optimized oil-gas circulation and cooling systems, significantly extending mechanical life while maintaining premium air quality. Combined with AIRERA IoT remote monitoring, it ensures 24/7 constant pressure and smart maintenance. The AIRERA 250kW series empowers large-scale industrial systems to achieve a green, low-carbon transformation through robust high-pressure power and ultimate frequency-drive efficiency.
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.

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

High pressure implies higher heat and stricter sealing requirements. The AIRERA 250kW series features an upgraded reinforced oil-gas separation system and high-pressure specialized seals to ensure zero leakage. Additionally, we have equipped the unit with extra-large capacity coolers and intelligent temperature-controlled fans to keep the lubricating oil at an ideal working temperature, preventing oil emulsification or carbonization.
Safety is the primary directive at AIRERA. This unit includes multiple built-in protection mechanisms: automatic overpressure shutdown, motor overload protection, high discharge temperature protection, and emergency power-off protection. All pressure-bearing components undergo rigorous hydraulic and airtightness testing to ensure rock-solid stability even when running at full 1.3MPa loads.
For large-scale overseas projects, this AIRERA series offers customizable enhanced cooling configurations and moisture/dust-proof motor treatments. In regions with unstable power grids, our inverters feature a wider voltage fluctuation tolerance (±10%), ensuring the machine provides uninterrupted power for large industrial stations even in the harshest external environments.
