An RP265 was bench tested when the input voltage was 110 volts and when the input voltage was 120 volts.

 The WPB test indicates that for this fan there is an average of about 4% less CFM and 7.5% less static pressure capacity when the input voltage is at 110 versus 120 volts.  What is more interesting is when comparing the performance when the wattage is at 100 watts
