Before measuring your static think carefully about where you are placing your probes and what you expect to see / what you diagnosing with the measurement. In this example, the centrifugal blower in a window air conditioner circulates 600 CFM on the "LO" setting when the blower motor is spinning at 800 rpm. If it is a single inlet wheel, the plate will be at one edge of the wheel opening, and the air can only enter from the edge opposite the hub plate. Most of what is sold are standard, squirrel cage type centrifugal wheels. A dirty blower wheel makes static pressure readings look awesome, because the fan isn’t moving the proper airflow. The best way to get this information is to ask them to draw a circle within a circle. 9-1/2", approx. This is easy to remember because the D & F both come before W & L in the alphabet. Wider would probably help a little as long as it won't rub the chassis or stick out past the bucket.
