Custom 22kW to 315kW Fixed Speed Two Stage Air Compressor

Elily’s Custom 22kW to 315kW Fixed Speed Two Stage Air Compressor features a two-stage compression design for reduced operational load and durable, worry-free SKF imported bearings. Customizable pressure ranges (0.8–1.6 MPa) and a robust, easy-to-maintain fixed-speed configuration make it a cost-effective choice for stable air supply in large and medium-sized factories.

I. Two-Stage Compression Structure: Lower Operational Load, Higher Durability
Utilizes independent high- and low-pressure screw rotor groups for staged compression. Air undergoes inter-cooling after the first stage before entering the second stage; this splits a high single-stage compression ratio (typically 8–9) into two stages of approximately 3 each. This effectively reduces the load on the air-end and minimizes heat loss, resulting in lower operational stress and a lower failure rate compared to single-stage compressors—making it ideal for continuous, 24-hour industrial operations.

II. Upgraded Rotor Profile: Stable Efficiency During Long-Term Operation
The unit employs a high-efficiency asymmetric rotor profile, upgrading from traditional line sealing to a sealing-strip design. This results in tighter meshing clearances and higher volumetric efficiency, boosting long-term operating efficiency by 5%–10% compared to standard models. The large-diameter, low-speed design minimizes mechanical friction and noise, slowing the aging and degradation of the air-end.

III. SKF Imported Heavy-Duty Bearings: Extended Service Life
The two-stage air-end comes standard with Swedish SKF imported bearings at both ends, offering high load-bearing capacity and impact resistance for continuous, heavy-duty operations. In 24/7 industrial environments, bearing wear is minimal, significantly extending the overhaul interval. The service life exceeds that of models with standard bearings by over 30%, reducing long-term equipment replacement and maintenance costs.

IV. Fixed-Speed Direct Drive: Simple Structure, Easy Maintenance
Equipped with an industrial-standard fixed-speed motor, the direct-drive system eliminates transmission losses associated with gearboxes, ensuring stable and reliable efficiency. Free from complex variable-frequency electronic components, the circuitry is simple and spare parts are readily available. Routine maintenance involves only standard replacement of filters and lubricant; no specialized personnel are required on-site, allowing for stable operation even in unmanned workshops at large and medium-sized factories. V. Customizable Pressure Range to Suit Diverse Operating Conditions

The Custom 22kW to 315kW Fixed Speed Two Stage Air Compressor offers customizable pressure specifications—including 0.8 MPa, 1.0 MPa, 1.3 MPa, and 1.6 MPa—to meet specific requirements, eliminating energy waste caused by excessive pressure. It precisely matches the standard operating pressures of various industries, such as textiles and chemical fibers, mechanical processing, mining and metallurgy, and food packaging, allowing a single model to adapt to a wide range of production scenarios.
