Core Components+ System Advantages

IE4 Premium Efficiency（IE5 Optional）, Low-Noise,PM Motor(IP65),Dual VSD Screw Air Compressor

Wide Speed Range & Precise Control
Adjustable speed (40%~100%) with ±0.1% precision for stable operation
Dual Inverter for Stable Temperature & Pressure
Energy-efficient dual-frequency drive maintains consistent output.
Top-Exhaust Air-Cooled Design
External suction and upward ventilation for easy installation and heat dissipation.
Premium SKF/FAG 6-Bearing System
High-grade bearings (75+ rating) enhance durability and safety.
High-Efficiency, Low-Noise Host Design
Large rotor reduces noise (<65 dB), vibration, and energy consumption (up to 30% savings).
Intelligent Cooling & Low Oil Temperature
Stable thermal control (±2°C) ensures reliability and quiet performance.
Advanced Oil-Gas Separation (<3 ppm Residual Oil)
Custom oversized separator minimizes pressure loss and air contamination.
