Radon Fan
Performance
Lots of Other Info
Fan performance at sea level will
degrade if the same fan is operated at a higher elevation even if the
barometric pressure is the similar. WPB benched tested the same
FanTech HP220 fan at three different elevations using the same setup in
each bench test and including the difference in barometric pressure,
temperature and relative humidity. The graph below illustrates the
results. The general rule is to figure a 3% loss for each 1000
feet of elevation.
This test WPB made indicated the
loss was less than.
