The air end is designed with big rotor rotating at low speed, if contains two independent compression units. It features high efficiency, low noise, low vibration, high reliability, low compression ratio in each stage, less leakage loss and higher volume efficiency. Under the same power, two units take the load, lower the loadd on each bearing making the part longer life.
The motors are high efficiency and energy-saving permanent magnet motors with protection level of IP54. They are strictly selected according to the requirements of applications of air compressor. They all meet the grade 1 energy efficiency national standard. Both torque and load can meet special design standard so as to achieve optimization of motor efficiency and power factors under loading condition. The optimized coefficient has about 5%-8% advantage comparing with other motors.
High efficiency oil-air separator with unique and simplified design, aggregated separator core and oil return device,its service life is 6,000
hours. Oil filter uses low-pressure design with service life reaching as long as 4,000 hours, and the high filtering degree protects bearing
and rotor.
Filter does not change the direction of air flow. Air directly runs through filtering media. It reduces the loss of air pressure, saves more
energy than traditional filter, has larger filtering area, higher degree of compactness andd longer life.
It adopts highly efficient fin-type cooler with large heat exchanging area, surplus of heat exchange of 30% and better cooling result, it can normally operate under the environment temperature at 45°C.
New type of integrated inlet valve with professional design, air inlet adjustable range is between 0-100%. It has valve regulation with small pressure lose, stable movement and long life. As the key part of inlet, magnetic valve adopts famous international brand that absolutely guarantees the operating safety as well as the economical operating control of air compressor.
Simple operation system, user language switches between English and Chinese. It intelligently monitors and manages air filter, oil filter, oil seperator, lubricating oil as well as running time. Furthermore, it has remote monitoring and control functions to be chosen by user.
Adopts universal frequency converter forming variable speed power transmission system, it saves energy, reduces production cost, increases productivity and improve product quality.
