I'm trying to determine how to achieve laminar flow @ 100 feet per minute using the following filter:

24" x 36" x 6" @ 99.99% at 0.3µm, Airflow: 805cfm @ 0.90” w.g

Here are my calculations so far:

The area for the filter is: 2ft x 3ft = 6ft2

I multiply the required air speed with my filters area:
100 ft/min x 6ft2 = 600ft3/min

My questions are:

#1. Is achieving laminar flow at 100ft/min as simple as finding a blower that will move 600cfm thru this filter at a static pressure of 0.90"(225Pa)?

#2. What does the filter's airflow of 805cfm @ 0.90” w.g mean?

Constructive criticism welcome along with any insights;)
