Different Meshes/Filters Tested - How Restrictive Are They?

jmke · 19th May 2009, 20:44

For each mesh/grill, I noted the anemometer reading with the filter installed on the intake side of the wind tunnel and then again immediately after removing the filter. There's some turbulence inside the tunnel which caused my anemometer readings to bounce around a bit, so I just averaged out the numbers over a period of a few seconds and noted the before/after numbers for each mesh.

As I mentioned above, the main thing that I wanted to check with these meshes is their noise level with the Scythe S-Flex fans but figured that, since I actually have a little anemometer, I may as well check the air flow. Almost all of the meshes/grills are noisy when installed directly adjacent to the fan body, so I used an extra fan body as a shroud - made a world of difference, especially with the Ultra Kaze.
