■ Motor overload protection.
■ The pipeline system is designed according to the design pressure, and the reasonable pipeline is selected, the pipeline pressure loss is low, and the energy efficiency of the unit is improved
■ The use of 304 stainless steel pipes will not rust and corrode even under high temperature and humidity conditions, and the service life is longer
■ Separate design for cold and hot zone, no heat zone inside the unit, electrical components are in low temperature zone, longer service life
■ Adopt frequency conversion system, more energy-saving, special control system, multi-channel pressure sensor and multi-channel temperature sensor to comprehensively detect the running state of the unit; the user interface is more friendly, the control is more accurate and reliable.
Water-lubricated screw air end
1. High-quality stainless steel casing, there is no risk of corrosion inside and outside the machine head
2. Using water as the compression seal and cooling medium, the use cost is low.
3. With advanced sealing and isolation technology, compressed air is cleaner and can be pure and oil-free.
4. The axial and radial forces of the single screw are balanced, and the star wheel rotates freely with the screw under the lubrication of the water film. Therefore, the host components run smoothly under low load, ensuring low noise and durability.
Inner rotor fan
1. IP44 cooling fan, Class F insulation;
2. Compared with the outer rotor fan, the inner rotor fan has higher air pressure, more air volume, and better cooling effect;
3. Due to high wind pressure, the cooler and filter are less likely to be blocked
