Experience unparalleled efficiency and reliability with our Portable Oil-Lubricated Twin-Stage Screw Air Compressor. Powered by an Electric Motor Engine and featuring a Direct Driven system, this compressor ensures robust performance and enduring durability for all your industrial needs.
Two-Stage Air End
Our air end features a robust large rotor and low-speed design. It includes two independent, high-efficiency compression units that deliver low noise, minimal vibration, and exceptional reliability. The small compression ratio at each stage reduces leakage and enhances volume efficiency, allowing for optimal performance under the same power. The dual-head load distribution minimizes bearing stress, significantly extending service life.
Direct-Connected Rotation Motor
Featuring insulation grade F and protective grade IP55, this motor ensures a stable flow rate, constant load, and impressively high efficiency and durability.
Aluminum Intake Valve
This valve operates by loading with electricity and unloading upon power loss, offering both air replenishment and noise reduction functions. With its smooth, wear-resistant surface, it guarantees stable and durable performance.
Reliable Oil and Air Separator
The vertical tangential cyclone separation structure ensures complete oil and air separation. It allows for easy cartridge replacement and significantly reduces maintenance costs.
Cooling System
Designed with a large heat exchange area, this system effectively prevents high-temperature malfunctions and reduces oil emulsification and coking caused by excessive heat.
Reliable Oil and Air Separator
Our vertical tangential cyclone separation structure guarantees a complete separation of oil and air, facilitating easy cartridge replacement and lowering maintenance expenses.
High Quality Rubber Tires
These durable vacuum tires (specification 175/65R15 84T) with iron wheels and tread pattern grip are suited for various complex site conditions.
Safe and Zero Leakage Connection
Sanzhi's innovative design eliminates traditional low-cost hydraulic hoses. With high-rigid pipes and flexible joint connections, we prevent bursts caused by aging, while the rubber-type O-ring ensures a flexible seal, eliminating leakage.
Intelligent Drive Control
Our newly designed intelligent drive controller supports under-voltage supplementation for equipment start-up. It operates efficiently within a voltage range of 300V-480V, protecting the motor from low-voltage burnout and eliminating the need for AC contactors, thereby reducing long-term maintenance costs.
Smart Touch Controller
Our smart touch controller integrates superior built-in intelligence, requiring minimal manual intervention. Equipped with a high-precision color electronic screen, it provides clear graphic displays, maintenance updates, fault alarms, and safety shutdown alerts.
