Another Filter Queen.
This time a Model 112b. I just finished cleaning the unit out today. I should add I did include all the dead space as part of the nozzle width as i usually do include that on other machines.
I'm also going to be running a week long test to see how Filter Queen retains airflow. I'll probably measure hose CFM day to day as getting set up for nozzle measurements is a pain but i'll probably take one the final day.
