Example for selection process:
The following data are the rated design points for MRC-085HWN1-R(C) rooftop packages:
Air flow = 3520CFM; External static pressure = 0.3in.w.g; Fan speed = 862rpm;
Power input = 1405W; The No. of turns = 1N.
To increase the ESP (External Static Pressure) to 0.4in.w.g, but maintain the airflow rate at 3500CFM,
please follow the steps below:
Step 1: Selection of new desired point.
From the table data, select the point that can meet both of the requirements.
ESP = 0.4in.w.g;
Air flow rate (Near or equal to) ≈ 3500CFM.
Step 2: Read fan speed, power input:
Air flow = 3483CFM;
Fan speed = 896rpm;
Power input = 1400W.
Step 3: Read number of turns for variable pitch pulley.
