* The Power Ratio Data is a conservative assumption based on HVAC applications which have shown that fans and pumps operate, on average, at 60% and 70% of maximum flow rate respectively.
​
** Remember, this result is only an estimate based on averages and assumptions. You should also consider additional savings to be gained from VFD application over and above the electricity rate, such as power factor improvement to.98 and reduced demand charges.
