Acceptance
Average downflow shall be 55 +/-5 FPM with all test points being within +/- 16 FPM.
Inflow Velocity Calculation - Primary Method
Note: The dress panel MUST be installed on the cabinet to obtain an accurate inflow
value.
The average inflow velocity for all Logics is 105 ±5 FPM, and should be determined by
converting the inflow volume to the average inflow velocity. The inflow volume is
measured directly by sealing a direct inflow measuring flowmeter to the face of the unit.
When corrected for local conditions, dividing the inflow volume by the opening area will
yield the average inflow velocity.
