Frequently Asked Questions
? What is the standard driving mode for these air compressors?
All models in this series utilize direct drive mode to optimize efficiency, lower vibration, and minimize transmission loss.
? Can the power supply configurations be customized?
Yes, the standard power supply configuration is 380V/50Hz/3P, but customizable configurations are available to meet your local industrial voltage standards.
? What type of startup system do these compressors use?
These compressors utilize Y-Δ (Star-Delta) start-up mode, which reduces the starting current demand on your electrical system.
? How does the lubricating oil capacity vary across different models?
Lubricating oil capacity ranges from 4 liters for the compact 10A model up to 125 liters for the high-capacity 350A industrial model. Refer to the specifications table for detailed sizing.
? What is the discharge pressure range for the 10A to 60A models?
Models 10A through 60A support discharge pressures of 0.7 MPa, 0.8 MPa, 1.0 MPa, and up to 1.25 MPa.
? What outlet connection options are available?
Smaller models (10A-30A) use G¼ to G1 thread connections, mid-range models use G1¼ to G2½ connections, and the largest models (300A-350A) feature DN100 flange connections.
