Air Filter (Field supply) Static pressure drop factors
If the air filter has been installed, then the ESP value has to be set.
For every increase in static pressure by 0.01 inWC, the ESP value should be increased by 1.
Note : Filters should be used a rating of MERV 4 or less.
If you use filters that has a rating MERV 5 or above, it can cause cooling & heating capacity
down.
