■ Durable and stable air end: two-stage integrated air end, third-generation asymmetric rotor technology; suitable for medium-pressure compression ratio matching, high volumetric efficiency; adopt heavy-duty bearings, and the rotor is well stressed; two-stage rotors are respectively passed gear drive, so that each stage of the rotor has the best linear speed; using a large rotor, low speed design, low noise and low vibration;

■ IE3 motor, save your electricity cost, IP54, B-level temperature rise is suitable for harsh environments such as large dust and high temperature;

■ Coupling connection, more energy saving;

■ Multiple noise reduction design, calculated according to noise theory, with special flame retardant muffler cotton inside, to reduce the noise of the unit and provide a quieter environment for use.

■ Independent air intake, reduce intake resistance, multi-function intake valve group, start without load, motor load is small. Use high-efficiency filters to effectively filter particulates in the air;

■ Centrifugal fan with high-pressure plate-fin cooler has high wind pressure, low noise, independent external suction, exhaust air upward through a specially designed air duct to prevent hot air from returning; plate-fin cooler has high heat exchange efficiency and internal pressure The loss is small, which can make the oil fully exchange heat, no heat zone;

■ The oil and air barrels developed professionally according to medium and high pressure conditions can achieve the best coarse separation effect under various conditions; after the second separation of the customized oil core, the final oil content of the air is not more than 3ppm;

■ The conventional maintenance parts (three filters) adopt openable door panels, the installation position is easy to replace, and the maintenance is more convenient

■ Specially designed main engine oil supply system to stabilize the oil supply pressure and ensure that the unit (especially the bearing) can get sufficient oil supply in the later period of long-term operation, the unit operates more stable and has a longer life.

■ High temperature shutdown protection;

■ Motor overload protection;

■ Overpressure safety decompression system;

■ Optimized shock absorption pad to reduce vibration and noise;

■ Dedicated 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.

■ The unit is equipped with an Internet of Things system, which can monitor the machine status on the mobile phone.
