Introducing our Portable Oil Lubricated Twin-Stage Screw Air Compressor! This state-of-the-art compressor, powered by an efficient Electric Motor Engine, is Direct Driven to ensure optimal performance and reliability. Experience unmatched power and precision with every use.
Two-Stage Air End
The air end adopts a large rotor, low-speed design, including two independent compression units, high efficiency, low noise, low vibration, and high reliability, each stage of compression ratio is small, with less leakage, and high volume efficiency. Under the same power, two heads bear the load, a small bearing hand, and a long service life.
Direct-Connected Rotation Motor
Insulation grade F, protective grade IP55, stable flow rate. Constant load, high efficiency and durability.
Aluminum Intake Valve
The working principle is loaded with electricity, and unloaded with loss of electricity, with the function of unloading and replenishing air, and the function of eliminating the noise of the host. Stable and durable performance, smooth surface and wear-resistant.
Reliable Oil and Air Separator
Vertical tangential cyclone separation structure, complete separation of oil and air, easy replacement of cartridge, and reduced maintenance cost.
Cooling System
Large heat exchange area design effectively prevents high-temperature machines and reduces oil emulsification and coking caused by high-temperature.
Reliable Oil and Air Separator
Vertical tangential cyclone separation structure, complete separation of oil and air, easy replacement of cartridge, and reduced maintenance cost.
High Quality Rubber Tires
The tire specification is 175/65R15 84T, vacuum tires, iron wheels, durable, tread pattern grip, applicable to a variety of complex site conditions.
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.
Intelligent Drive Control
Newly designed intelligent drive controller can do under-voltage supplement for equipment start-up, start-up voltage of 300V-480V can be realized for equipment operation, and protection of the motor, to avoid burning the motor due to low-voltage start-up, eliminating the need for AC contactors, reducing the cost of late maintenance.
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.
