KAESER ASK 34-11 Screw Compressor – 18.5 kW at max. 11 bar
The KAESER ASK 34-11 is an oil-lubricated screw compressor with a drive power of 18.5 kW and a maximum operating pressure of 11 bar. At rated pressure, it delivers a flow rate of 2.98 m³/min—designed for large industrial consumers with high compressed air demands. The AIRBOX.2 heat recovery system allows the waste heat to be used for heating the facility or producing hot water, thereby reducing total operating costs.
The compressor block uses the proven KAESER SIGMA PROFILE rotor pair to deliver optimized air flow with low energy consumption. The SIGMA CONTROL 3 M control system, featuring a 5-inch color touchscreen display and an integrated ANYbus interface, monitors all operating parameters and enables integration into higher-level control systems. The IE3 drive motor operates at 400 V / 3-phase / 50 Hz. The sound pressure level is 67 dB(A). The dimensions are 800 × 1110 × 1530 mm (W × D × H) with a weight of 505 kg.
If an integrated refrigerated dryer is also required, KAESER offers the ASK 34-11 T model from the “With Refrigerated Dryer” series, which has a pressure dew point of +3 °C.
