Frequently Asked Questions (FAQ)

What driving mode is used in these air compressor models?

All models in this series, from 10A up to 350A, utilize a Direct Drive system to ensure maximum transmission efficiency and reliable performance.

What is the standard startup mode for these compressors?

The standard configuration for all models is Y-Δ (Star-Delta) start-up, which effectively reduces starting current and minimizes electrical load impact during start.

Can the power supply configurations be customized?

Yes. While the standard power supply configuration is 380V/50Hz/3P, custom voltage and frequency configurations can be provided to meet your specific regional power grid requirements.

How does the lubricating oil quantity differ between smaller and larger models?

The lubricating oil requirements scale based on system capacity, ranging from 4 liters for the compact 10A model to 125 liters for the high-capacity 300A/350A models to ensure optimal cooling and lubrication.

What types of outlet connection sizes are available?

Outlet configurations range from small G¼ threaded connections for low-flow models to standard thread sizes like G1, G1¼, G2, G2½, and DN100 flange connections for large industrial models (300A and 350A).
