15kW Fixed-Speed Single-Stage Screw Air Compressor

Technical Definition & Performance

The 15kW Fixed-Speed Single-Stage Screw Air Compressor is an industrial-grade rotary power unit designed for continuous base-load operations. By utilizing a high-precision single-stage compression profile, it eliminates the pressure fluctuations common in piston units, delivering a stable 2.3–2.6 m³/ min discharge capacity for critical pneumatic logic and automation.

Core Advantages

Volumetric Efficiency: Our air end utilizes a 5:6 lobe ratio, ensuring maximum displacement with minimum internal leakage.

Thermal Management: Oversized 304 stainless steel piping and heavy-duty aluminum radiators prevent emulsification of the lubricating oil.

Motor Protection: Equipped with an SKF bearing-supported motor and Class F insulation, providing a high service factor for 24-hour operation.

Heavy-Duty Filtration: Three-stage oil-gas separation system ensures residual oil content remains below 3ppm.

Technical Specifications

Industrial Application Nodes

As a specialized manufacturer, we have optimized this 15kW model for specific load profiles:

Metal Fabrication: Stable pressure for CNC laser cutting (assist gas).

Plastic Injection: Reliable pilot air for valve gate controls.

Electronics: Clean, dry air for SMT pick-and-place lines.

Quality Control & Direct Factory Traceability

Every 15kW Fixed-Speed Single-Stage Screw Air Compressor leaving our China factory undergoes a rigorous performance audit.

Vibration Analysis: Peak-to-peak displacement measured to ensure structural resonance is avoided.

Full-Load Thermal Run: Continuous 4-hour operation at 100% load to verify heat dissipation stability.

Why Settle for Less? (Competitor Analysis)

Ours: Uses heavy-duty cast iron housing for the air end to prevent thermal deformation.

Theirs: Use lightweight aluminum alloys that sacrifice long-term structural alignment.

Ours: Integrated minimum pressure valves (MPV) for optimized lubrication start-up.

Theirs: Simplified check valves that often lead to oil backflow issues.

FAQ

Q1: What is the specific FAD (Free Air Delivery) tolerance for this 15kW model?

A: We follow the ISO 1217, Annex C standard. Our 15kW Fixed-Speed Single-Stage Screw Air Compressor maintains a tolerance within ±5%. Unlike generic suppliers, we provide the actual flow rate data at the discharge valve, not the theoretical air end displacement.

Q2: How does your 1:1 Direct Drive compare to Belt Drive systems in this power range?

A: In a 15kW Fixed-Speed Single-Stage Screw Air Compressor, direct coupling eliminates the 2–3% transmission loss and radial load on motor bearings associated with belts. This reduces the Mean Time Between Failures (MTBF) and simplifies alignment maintenance.

Q3: Can your factory accommodate specific electrical grid requirements (e.g., 220V/3P/60Hz or 440V/3P/50Hz)?

A: Yes. As a specialized China manufacturer, we offer customized winding and contactor configurations (Schneider/Siemens components) to meet diverse international voltage standards while maintaining CE compliance.

Q4: What is the Specific Power Consumption (SPC) of this unit?

A: This single-stage unit is optimized for base-load efficiency with an SPC of approximately 6.8–7.2kW/(m³/min) at 8 bar. For facilities with fluctuating demand, we recommend our VSD series, but for constant 100% load, this fixed-speed model offers the best ROI due to lower initial CAPEX.
