According to this formula I have a lot of questions.
Blockquote Q = V x A
-
Depth of HEPA filter is calculated for A (area) or not ?
-
Pressure drop is pressure differential ?
-
My problem is an air velocity in this LAFWs is 70 fpm (lower than criteria). If Q is fixed (control humidity in LAFWs) and A is also fixed (914 X 610 mm.), how can I increase V in this case ?.
>> Decrease pressure drop across HEPA filter (Changing media : glass fiber to eFRM)
>> Decrease depth of this HEPA filter that makes resistance of its low
>> Overhaul this LAFWs (resizing)Thanks for ur kindness
