FAQ

Q: Why should I choose compressed air instead of Nitrogen ($N_2$) or Oxygen ($O_2$) for my 4kW–8kW laser?

A: Compressed air can drastically reduce your auxiliary gas costs by up to 60–80% compared to bottled or liquid nitrogen. For 4kW–8kW lasers, high-pressure compressed air provides enough kinetic energy to blow away slag efficiently, offering excellent cutting speeds on stainless steel and carbon steel under 8-10mm.

Q: What exact air pressure and flow rate (FAD) do I need for an 8kW fiber laser?

A: Generally, an 8kW laser cutter requires an operating pressure of 1.4 to 1.6 MPa. The flow rate depends on your cutting nozzle diameter; usually, a system delivering 1.5 to 2.5 $m^3/\text{min}$ is recommended. Please contact our engineering team with your laser brand model for a precise calculation.

Q: How does KINKONA protect my expensive laser lenses from oil and water contamination?

A: This is our core advantage. We utilize a 4-stage ultra-precision filtration train combined with an oversized refrigerated or desiccant dryer. This removes liquid water, vapor, and oil aerosols down to $\le 0.001 \text{ mg}/m^3$. We also offer a 100% oil-free solution for zero-risk high-end manufacturing.

Q: How do you handle international after-sales service and spare parts replacement?

A: We provide comprehensive global support:
1.Detailed video guides and documentation for routine maintenance (e.g., filter element swaps).
2.24/7 video consultation with senior cross-border service engineers.
3.Core electrical parts use world-renowned brands (such as Schneider), allowing easy local sourcing for common parts.
4.DHL/FedEx global express shipping for any original factory spare parts.

Q: What is the average lead time and shipping availability for international B2B orders?

A: Standard configuration compressors (e.g., 1.6 MPa integrated systems) are usually in stock and can ship within 7–10 days. Customized voltages (e.g., 220V/3Phase/60Hz, 440V, etc.) or custom OEM orders typically take 15–20 working days. We provide standard export-grade seaworthy plywood crating for worldwide transport safety.
