AIRERA 90kW Screw Air Compressor: Frequently Asked Questions (FAQ)
What are the advantages of the 90kW model in large-scale production compared to lower-power models?
The 90kW model offers a larger displacement (approx. $15.5 - 16.8text{ m}^3text{/min}$), capable of supporting multiple automated production lines simultaneously. It reduces piping complexity compared to using multiple smaller units and offers superior Specific Energy Requirements (SER) under high loads.
How is low noise and vibration ensured during 90kW high-power operation?
AIRERA utilizes a precision-balanced direct-drive architecture, eliminating vibration-prone gear sets. Combined with thickened soundproof enclosures and heavy-duty anti-vibration bases, noise levels are kept at industry-leading lows even during full-speed operation.
Can the 90kW water-cooling system support 24-hour continuous full-load operation?
Yes. The system is designed for heavy-duty use, featuring shell-and-tube coolers with large heat exchange surface areas. Even in high ambient temperatures, it maintains precise thermal control via water flow adjustment, ensuring no overheating shutdowns.
