Frequently Asked Questions

Q: What driving mode do these air compressors use?

All models listed in our technical specifications utilize a Direct Drive mode, ensuring optimal power transmission, lower vibration, and reduced energy losses compared to belt-driven models.

Q: Can the power supply configuration be customized?

Yes. While the standard power supply configuration is 380V/50Hz/3P, customized electrical configurations can be requested to meet specific regional requirements.

Q: What is the advantage of the Y-Δ (Star-Delta) start-up mode?

The Y-Δ (Star-Delta) start-up configuration reduces the initial starting current, which protects the electrical motor and prevents voltage fluctuations in your facility's power supply grid.

Q: How do I determine the right model based on Free Air Delivery (FAD)?

Free Air Delivery (FAD) varies according to the discharge pressure (ranging from 0.7 MPa to 1.25 MPa). You should match your air-operated equipment's volume requirement (m³/min) at its operating pressure to the corresponding capacity of the compressor models.

Q: Does the lubricating oil capacity vary significantly between models?

Yes, the lubricating oil capacity is scaled according to machine size and heat dissipation needs, starting from 4 Liters for the 10A model up to 125 Liters for the larger 350A industrial units.
