The ZGM-II Series Two-Stage Variable-Frequency Stationary Screw Air Compressor combines two-stage compression technology with permanent magnet frequency conversion—our most advanced solution for high-pressure, high-efficiency industrial scenarios. Unlike single-stage compressors, it compresses air in two stages (low-pressure stage → high-pressure stage), reducing compression ratio per stage, lowering energy loss, and delivering stable high pressure (up to 1.6MPa). With motor power from 15KW to 315KW and free air delivery from 1.6 m³/min (1.6MPa) to 50 m³/min (0.8MPa), the ZGM-II Series is ideal for industries requiring high-pressure air (e.g., heavy machinery, precision electronics).
Heavy machinery (e.g., excavators, loaders) needs high-pressure air (1.2MPa-1.6MPa) to charge hydraulic systems. The ZGM-II Series’ two-stage compression delivers stable high pressure with 15% higher efficiency than single-stage high-pressure compressors. A construction machinery factory using ZGM-II-150HP (110KW) can charge 8-10 excavator hydraulic systems per hour, reducing charging time by 20%.
Semiconductor manufacturing requires ultra-high purity, high-pressure air (1.0MPa-1.2MPa) for wafer cleaning. The ZGM-II Series’ upgraded filtration system (three-stage air filtration + high-precision oil filter) ensures air purity (particle size < 0.1μm, oil content < 1ppm), meeting ISO 8573-1 Class 1 standards. This eliminates wafer contamination risks and improves production yields.
Ship painting requires high-pressure air (0.9MPa-1.2MPa) to drive large spray guns and cover large surfaces. The ZGM-II Series’ variable frequency technology adjusts air flow based on the number of spray guns in use (e.g., 5 guns → full speed, 2 guns → reduced speed), saving 25-40% energy compared to fixed-speed high-pressure compressors. Its large oil-air separation barrel (100L-200L) also ensures continuous air supply for 12+ hours of non-stop spraying.
• Dual-Efficiency Advantage: Two-stage compression reduces energy consumption by 18-25% vs. single-stage high-pressure compressors; frequency conversion further cuts energy use by adapting to variable demand.
• High-Pressure Stability: Compression ratio per stage ≤ 3.5 (vs. single-stage ≥ 5), minimizing air temperature rise (outlet air temperature < 45℃) and ensuring pressure fluctuation ≤ ±0.01MPa.
• Durability: Reinforced screw elements (made of high-strength alloy steel) and upgraded bearing system (imported from SKF) extend the air end’s service life to 12,000 hours—50% longer than standard models.
• Two-Stage Screw Air End: Low-pressure stage (large rotor diameter) for initial compression, high-pressure stage (small rotor diameter) for secondary compression; optimized rotor profiles reduce air leakage and improve efficiency.
• Intelligent Cooling System: Dual-fan cooling (for models ≥ 75KW) with temperature-sensitive control—automatically adjusts fan speed based on air temperature, avoiding overcooling/overheating and saving energy.
• Control Panel: 7-inch color touch screen with PLC control, supporting data logging (1 year of energy consumption and fault records) and integration with factory IoT systems for centralized management.
• Customized Solutions: We design customized ZGM-II configurations (e.g., pressure adjustment, filtration level, IoT integration) for special industries (e.g., aerospace, food processing).
• On-Site Maintenance: Our global service network provides on-site maintenance within 48 hours for urgent repairs (covering 90+ countries), with a dedicated technical specialist assigned to each large client.
• Training Programs: Free technical training for client engineers (including two-stage compression principles, frequency conversion maintenance, and troubleshooting) to ensure independent operation and maintenance.
