Concurrent Balance Values
Axiom Inflow and Inlet Valve flow numbers are established by a direct measurement of
air flow. Traditional exhaust system measurements are made using either an
anemometer or Pitot traverse methodology. Because of these different methodologies,
the total volume of air flowing through the exhaust system will vary.
