One of the ways in FAS Series compressors maximizes energy savings is with a variable speed drive (VSD). The VSD allows you to match your energy usage to current system demands, eliminating the need to overpressure the system, so you’ll save money by not wasting energy.
In addition, the softstarting capability of firstAir’ VSD reduces inrush current requirements, decreasing your power demand — and, of course, increasing your energy savings
The VSD — time-proven directly coupled design — oﬀers faster response and greater operational eﬃciency
Variable operation slows air end speed, which lowers energy costs and reduces noise
Matching the operating speed with changes in demand reduces component wear
The VSD enhances quality by stabilizing air pressure at + 0.1 kg/cm²
Built-in DC choke protects against harmonic disturbances and eliminates the need to source additional corrective devices
