NOTES :

1. Airflow based upon dry coil at 230v with factory approved filter and electric heater (2 element heater sizes 18 through 36, 3 element heater sizes 42 through 60).
2. Airflow at 208 volts is approximately the same as 230 volts because the X13 motor is a constant torque motor. The torque doesn’t drop off at the speeds the motor operates.
3.  To avoid potential for condensate blowing out of drain pan prior to making drain trap: Return static pressure must be less than 0.40 in. wc. Horizontal applications of 042 – 060 sizes must have supply static greater than 0.20 in. wc.
4.  Airflow above 400 cfm/ton on 048 – 060 size could result in condensate blowing off coil or splashing out of drain pan.
5. Shading – Airflow outside 450 cfm/ton.

Static Pressure Correction from Dry to Wet Coil (inches of water column)

Airflow performance chart was developed using fan coils with DRY coils.
When taking a static reading across a WET coil, adjust the static pressure numbers by adding the values in this table (for a given CFM, wet coil will have greater static pressure drop than dry coil).

Static Pressure Correction for Electric Heaters (inches of water column)

Airflow performance chart was developed using fan coils with 10 kW electric heater (2 elements) in the 1800 – 3600 model sizes, and 15 kW electric heaters (3 elements) in the 4200 – 6000 model sizes.
When using a different number of heater elements, adjust the static pressure numbers by adding or subtracting the values in this table (for a given CFM, more electric heater elements create higher static pressure drop).
