Energy Savings Calculator

Estimate your potential energy savings by switching from a fixed-speed compressor to a Variable Speed Drive (VSD) compressor.

Average Load Profile (%)

Average air demand as % of full capacity

Estimated VSD Energy Savings: 35%

VSD compressors typically save 25–45% on energy costs compared to fixed-speed units at partial loads.

• Variable Speed Drive (VSD) compressors adjust motor speed to match actual air demand
• Fixed-speed compressors run at full power even at low demand, wasting energy
• VSD savings are greatest when demand fluctuates throughout the day
• Most industrial facilities operate at 60–70% average load, making VSD ideal
