1. Truly oil-free screw air compressor.<\/b><\/strong>The airend operates completely without lubricating oil, ensuring 100% oil-free compressed air.<\/p>\n

2. No cooling oil is required for the airend jacket<\/b><\/strong>. Pure water is used to remove acidic and alkaline contaminants from the compressed air, resulting in cleaner and higher-quality compressed air.<\/p>\n

3. Lifetime stable and reliable oil-free technology.<\/b><\/strong>All components in contact with the compressed air are manufactured from 304 or 316 stainless steel or other corrosion-resistant materials. Within the pressure range of 0.15\u20131.6 MPa, single-stage compression is easily achieved, reducing the number of moving parts and providing a simpler, more reliable structure.<\/p>\n

4. Features direct-drive technology with the motor and airend operating at the same speed.<\/b><\/strong>The maximum airend speed does not exceed 2,980 rpm, significantly extending the service life of the bearings and rotors.<\/p>\n

5. Superior energy efficiency. <\/b><\/strong>Direct water injection cools both the rotors and the compression chamber, maintaining the internal compression temperature below 40\u00b0C. This enables near-isothermal compression and delivers higher compression efficiency with lower energy consumption.<\/p>\n

6. Direct water injection also seals the rotor clearances, eliminating the need for rotor coatings.<\/b><\/strong>This avoids coating peeling and ensures long-term high-efficiency compression performance.<\/p>\n

7. Equipped with dual compression chamber technology, allowing one rotor to serve two compression chambers.<\/b><\/strong>This innovative design surpasses conventional two-stage compression while eliminating the need for intercooling, reducing power loss and improving overall efficiency.<\/p>\n

8. Low maintenance cost.<\/b><\/strong>Routine maintenance only requires replacement of the air filter element and water filter element, minimizing operating costs and downtime.<\/p>\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n
