Product Features
1. 100% Oil-Free Compressed Air
* Water is used as the lubricating and sealing medium, ensuring the compressed air is completely oil-free (Class 0 certified), meeting the stringent air quality requirements of the food, pharmaceutical, and electronics industries.
2. Advantages of Water Lubrication Technology
* Water replaces lubricating oil, directly cooling the compression chamber, improving heat dissipation efficiency and extending the life of the air conditioner.
* Low Maintenance Cost: No regular lubricating oil and oil filter changes are required; only the water circulation system needs to be maintained.
* Environmentally Friendly and Non-Toxic: Water is used as the medium, resulting in zero pollution and simplified wastewater treatment, meeting green manufacturing standards.
3. Permanent Magnet Variable Frequency Motor (PM Motor) for High Efficiency and Energy Saving
* IE4/IE5 Ultra-High Energy Efficiency: Permanent magnet motors are 10%-15% more efficient than conventional asynchronous motors, with even more significant energy savings at partial loads.
* Wide Frequency Adjustment (25%-100%): The variable frequency drive precisely matches air demand, avoiding no-load waste and achieving 30%-50% energy savings.
4. Low Noise and Vibration
* Water-based lubrication reduces noise: The damping effect of water reduces mechanical friction noise, with overall noise typically below 65dB(A).
* Permanent magnet motor operates silently: No excitation loss, resulting in minimal vibration.
5. High Reliability and Long Life
* Oil-free lubrication reduces the risk of carbon deposits. Key components feature corrosion-resistant coatings, and the piping and housing are made of stainless steel.
* Intelligent Control and Protection: Real-time monitoring of water temperature, pressure, and flow prevents overheating and scaling.
