I am trying to model a sewage detention facility using eQuest, which includes a odor control system. In the Air-Side HVAC, when I try to input 20 inch WG static pressure for fan (large head loss when pushing odorous gas through carbon chamber. ~16 in WG), eQuest is not allowing to do that because the maximum value allowed is 15 inch WG. Also try to input 20 inch WG in the exhaust fan, but the maximum value allowed is 10 in WG. I am wondering why eQuest has this limitation? Is there any way I can input more than 15 in WG static pressure for fan or exhaust?
