Indoor Air Flow Data

Indoor air flow may be determined by measuring the
external static pressure (ESP) of the duct system and
then using the chart below to determine the actual
airflow. Under no circumstances should the Zoneline
unit be operated to an ESP in excess of .3" W.C..
Operation of the Zoneline under this condition will result
in inadequate air flow thus leading to poor performance
and/or premature component failure.

NOTE: Values taken at 70-75°F ambient temperature
Your airflow should be balanced based on many
factors, such as available ESP, room CFM, and
ductwork. Consult an HVAC engineer for proper
applications. External static pressure (ESP) can be
measured with a manometer or pitot tube. Once this
ESP is established, you can calculate the CFM using
the above chart.

• = Recommended Mid Range
Higher CFMs tend to increase Sensible capacity,
enhance room circulation and increase duct noise,
while lower CFMs tend to increase Latent capacity
and reduce noise.

The return air to the Zoneline unit MUST NOT be
ducted, and all units MUST have a free return air

configuration to perform properly.

The total flow rate (CFM) and external static pressure

The collar on top of the unit accepts standard 10"

increase static pressure.
