Technical Specifications

Component Details
1. High-efficiency Permanent Magnet Motor
Insulation grade F, protective grade IP55, soft start operation, stable flow rate. The constant torque range and weak magnetic range are wider, The efficiency of the permanent magnet motor is higher by 20-30% than that of the regular motor.

2. Twin-Screw Efficient Mainframe
The rotor adopts a new type of energy-saving and efficient route, with isobaric ratio, and low-speed design, and the energy saving of ordinary air compressors is about 30%.

3. Integrated Frequency Converter
Adopt the top frequency system in China, with a wide range of speed regulation, and high precision. Quality stability, to ensure that the pressure transmitter signal is transmitted.

4. Smart Touch Controller
Superior built-in intelligence requires minimal manual operation. A high-precision color electronic screen, clear graphics display, and indication of maintenance information, fault alarms, and safety shutdown alarms.

5. Special Type Intake Valve
Automatic control of the opening, to ensure the engine fuel injection and lubricating oil circulation.
Ultra-low oil circuit loss, overall efficiency improvement.
Normally open solenoid valve control, emergency stop automatically closed, prevent oil injection.

6. Cooling System
Large heat exchange area design effectively prevents high-temperature machines and reduces oil emulsification and coking caused by high-temperature.

7. Excellent Air Filter
An air filter with excellent air purification capability ensures a clean air system and three-stage filtration to maximize air purification and meet standard emissions. It can remove a lot of steam and a small amount of dust gas occasions.

8. Reliable Oil and Air Separator
Vertical tangential cyclone separation structure, complete separation of oil and air, easy replacement of cartridge, and reduced maintenance cost.

9. High-Quality Soundproof Cotton
Compact noise reduction housing, achieving no vibration amplitude during operation, cooperates with high-quality soundproof cotton to further improve noise reduction levels.

10. Iron Oil Pipe & Air Pipe System
Iron is resistant to high temperature, low temperature, and high pressure, suitable for bad working conditions, completely leak-free, and maintenance-free.

11. Safe and Zero Leakage Connection
Sanzhi has abandoned the traditional low-cost hydraulic hose design. Sanzhi uses High-rigid pipes and flexible joint connections, avoiding bursts typically caused by aging, rubber type 0-ring offers a flexible seal preventing leakage.

Product Features
Energy saving
Saves 50-60% of electricity compared to traditional air compressors.
