With Air-Cooling 37 – 355kW

KAESER’s air-cooled, oil-free rotary screw compressors are designed to deliver reliable, high-performance compressed air even in demanding ambient conditions up to +45 °C. With outputs up to 355 kW and innovative cooling features, they’re ideal for facilities without a water-cooling infrastructure. These systems combine energy efficiency, easy maintenance, and integrated heat recovery for enhanced overall performance.

• Efficient heat recovery via high-thrust radial fans
• Standstill fan for residual heat removal in standby mode
• Swivelling aluminium heat exchanger for easy cleaning
• Water jacket-cooling boosts efficiency and extends gear oil life to 18,000 hours
• Demand-based airflow regulation for optimal cooling
