250KW 46.5~35m3/min Oil Inject Screw Compressor


AIRERA 250kW Flagship Oil-Injected Screw Compressor: The Iron Backbone of Heavy Industry

As the "Performance Titan" of the AIRERA family, the 250kW Series is purpose-built for large-scale industrial applications and centralized air supply systems. Delivering a massive output of up to 46.5 m³/min, this unit combines immense power with an impressive energy efficiency ratio. It is the premier choice for steel mills, large-scale chemical plants, and automation hubs seeking robust and reliable pneumatic power.

Key System Advantages
Air end block – reliable centrepiece Design in Germany

The centrepiece of the compressor is the air end, which is constructed and manufactured with the most modern production methods in Germany. The optimal air end for your compressor can be used on a modulating basis. In frequency-controlled units, where the operating pressure changes, adjustments can also be made on the frequency controller to optimally adjust the speed of the compressor to the compressor performance.

Oil separation system

Compressors up to 132 kW are equipped with external separators that can be changed in a simple spin-off/spin-on process. Larger units have an internal separator cartridge. Due to the excellent separation efficiency of the system as a whole, the compressors can be used in the pressure range of 5.0 to 15.0 bar. Special pressures on request.

Drives and electrics

The almost loss-free power transmission guarantees reliable, high-performance compressor operation. The regular maintenance requirement is reduced to lubrication of the motor. All the electronic components are brand products of leading manufacturers.

Frequently Asked Questions
Q1: How durable is the machine in high-intensity, 24/7 heavy industrial environments?
A: We guarantee durability through three dimensions:
  1. Heavy-Duty Bearings: Premium high-temperature resistant bearings with a design life of 60,000–100,000 hours.

  2. Triple-Proof Design: The electrical cabinet is built to resist dust, moisture, and vibration, suitable for harsh smelting or chemical environments.

  3. Independent Oil-Cooling Loop: Equipped with a high-precision thermostatic valve to ensure oil temperature stays in the "Golden Zone"—optimal lubrication without condensate precipitation.

Q2: What makes the filtration system unique for such high-capacity units?
A: Standard filters often fail or cause high pressure drops under a 46.5m³/min flow. AIRERA uses oversized filtration surface designs:
  • Air Intake: Nano-coated filter media with 99.9% efficiency protects the air-end from dust-related wear.

  • Oil Separation: Utilizes dual-parallel or extra-large separator tanks to ensure ultra-low flow velocity. This keeps oil carryover below 3ppm and significantly extends maintenance intervals.
