A variable speed drive air compressor adjusts motor speed to match real air demand instead of running at a fixed speed and cycling on and off.
How It Works
A frequency inverter varies the motor speed based on pressure feedback. When demand falls, the compressor slows down and draws less current.
Where It Saves the Most
VSD technology pays off when air demand fluctuates across shifts, production stages or seasons. The wider the variation, the larger the saving.
Considerations
VSD units cost more upfront, so the decision depends on your load profile and energy price. A simple profile analysis shows the payback.
