Here is my homemade air cleaner that I built for my shop. I used 3 High Volume Comair Rotron fans rated at 340cfm each. I have them wired to a 60 min dial style timer which is then fed into a 2 switch unit that allows me to turn 1, 2 or all 3 fans on. I have no idea how to tell how many times an hour it recycles the air in the shop, but I know it moves a lot of air and traps a lot (A LOT) of particles in the air.
The size was determined by looking at the 3 fans side-by-side and what filters were available. To keep the height of the case to a minimum, I ended up ordering filters from Filters Now. The unit has locations for 2 pre-fan filters and a post fan filter. In hind sight, I should of made it a little taller to use more readily available filters.
