The Gardner Denver ESM / VS 7–22 Series comprises a range of advanced, lubricated rotary screw compressors designed for superior energy efficiency, reliability, and flexibility in demanding industrial applications. Covering motor powers from 7 to 22 kW, this series is available in both fixed speed (ESM) and variable speed (VS) configurations to match varying air demand and optimize power usage. These compressors operate at a working pressure range from 5 to 13 bar, with volume flow rates from 0.94 to 4.10 m³/min (33.2 to 145 cfm), depending on the model and pressure setting. The fixed speed ESM 7–22 models are ideal for consistent air demand, while the VS models utilize integrated inverter drives to modulate motor speed, significantly reducing energy consumption in fluctuating load conditions. All units are equipped with Gardner Denver’s efficient screw air-ends and IE3 premium-efficiency motors, ensuring reliable performance and reduced lifecycle costs.
