Core Components+ System Advantages

100% Oil-Free Air Compressor with Triple Sealing System & Smart IoT Control

Certified 100% Oil-Free Air
● Triple sealing system guarantees pure oil-free air (Class 0, ISO 8573-1)
● Zero risk of oil contamination
Ultra-Precision AGMA 13 Gearing
● High-precision gearbox (AGMA Class 13) ensures smooth power transmission
● Withstands extreme operating conditions (dust, humidity, temperature fluctuations)
Next-Gen Rotor Design for Maximum Efficiency
● Optimized rotor profile improves airflow efficiency by 12–15%
● Stainless steel rotor core + special alloy coating provides:
✓ Heat resistance (up to 300°C)
✓ Anti-wear & corrosion protection
✓ 50% longer lifespan vs standard rotors
Leak-Proof Gearbox Protection
● Oil mist separator on gearbox vent captures 99% of lubricant vapors
● U-shaped pressure differential valve prevents oil leaks
● Maintains clean operation environment
Dual-Stage Air Intake System
● Two-stage filtration (pre-filter + main filter) ensures:
✓ Optimal air intake quality
✓ 5–8% higher compressor efficiency
✓ Extended component life
Smart IoT Monitoring & Control
● Real-time performance tracking (pressure, temp, energy use)
● Predictive maintenance alerts via cloud connectivity
● Remote troubleshooting reduces downtime
