Table 17: Air Filter Static Pressure Drop Factors.
If the air filter has been installed, the ESP value has to be set.
For every increase in static pressure by 0.01 in. wg, the ESP value must be increased
by 1.

Do not operate with less than the minimum airow. If an airow is used
below the minimum, there is a risk of damage to the product.
Airflow rates in the table above are listed in CFM.
Do not operate with less than the minimum airow. If an air-
ow is used below the minimum, there is a risk of re, which may
lead to physical injury or death.
