I. Technical Principles and Structural Features

Dual-Stage Compression Technology
- Working Principle : Air undergoes two compression processes via meshing screw rotors (male and female). After primary compression, the air enters an intermediate cooler for cooling, then enters secondary compression to reach high pressure.
- Advantages : Compared to single-stage compression, dual-stage compression reduces compression ratio, minimizes internal leakage and discharge temperature, and improves efficiency (saving 5%-8% energy), while extending equipment lifespan.
Permanent Magnet Variable Frequency Drive
- Motor Characteristics : Utilizes rare-earth permanent magnet synchronous motors, eliminating excitation current and improving efficiency by 5%-10% compared to traditional motors.
- Frequency Control : Adjusts motor speed via a frequency converter to achieve stepless regulation of air output, avoiding energy waste under partial load conditions (maintains over 90% efficiency at 40% load).
Direct-Drive Design
- Structural Integration : The compressor is directly connected to the motor, eliminating transmission devices (e.g., belts, gears) and achieving 100% transmission efficiency.
- Maintenance Advantages : Reduces failure points and maintenance costs with no transmission components.

II. Core Advantages

High Efficiency and Energy Saving
- Comprehensive Energy Saving : Dual-stage compression + permanent magnet VF + direct-drive design saves 30%-50% energy compared to traditional fixed-speed models, complying with GB19153-2019 Tier 1 energy efficiency standards.
- Case Study : An auto parts factory saved annual electricity costs of 376,000 yuan after retrofitting; an injection molding plant saved 1.27 million kWh annually after upgrading five units.
Stable and Reliable
- Pressure Customization : Supports full pressure range customization (0.7-1.3MPa) with pressure fluctuations controlled within ±0.01MPa.
- System Robustness : Overload protection and intelligent oil temperature control system (±2℃ precision) for high-load scenarios.
Intelligent Management
- Remote Monitoring : Supports mobile app remote start/stop, real-time energy consumption monitoring (daily/monthly/annual reports), and fault预警 (72-hour advanced warning).
- Multi-Unit Control : Intelligent parallel operation of multiple units, covering flow ranges of 10-200m³/min, with balanced air distribution.
Low Noise and Long Lifespan
- Noise Reduction : Oil-free lubrication design reduces noise to below 75dB.
- Maintenance Costs : Bearing-free permanent magnet motor design requires no maintenance; lubricant usage reduced by 50%.

III. Typical Application Scenarios

Industrial Production
- Automotive Manufacturing : Centralized air supply for 200+ terminals, improving pressure stability by 40% and product yield by 2.3%.
- Food Processing : Oil-free lubrication provides clean air sources complying with Class 0 hygiene standards.
Construction Work
- Spray Painting : Stable air pressure enhances coating quality, reducing paint waste by 30%.
- Pneumatic Tools : Continuous air supply ensures efficient operation of nail guns, jackhammers, etc.
Mining and Chemical Industries
- High-Altitude/High-Temperature Environments : IP55 protection rating for stable operation in humid environments (up to 80% humidity).
- Corrosion Resistance : Customizable stainless steel construction for corrosive gas environments.
