For Guidance Only. Does not account for fan-fan interactions, internal restrictions, fingerguards etc. This spreadsheet calculates the operating point where the filter pressure drop vs flow curve crosses the fan pressure drop vs flow curve, for combinations of filters and pc fans in parallel in an unrestricted container. It assumes all filters and fans operate at the same pressure drop. It may NOT provide reliable Clear Air Delivery Rates, since Particle Size Efficiencies are measured at much higher velocities.
