Freedoms

Well i tried a used 3600 and it's motor was not in the best of shape i only got 67.28 CFM from it. Then i got the idea to measure the S10E which uses the same fan and motor as the older freedoms then i did one of the newer S10 series machines with the new fan and strangely i got a lower result than last time and i couldn't figure out why but there's two factors that could have effected the S10D's flow #1 the metal rollers when brand new have additional resistance until it "breaks in" due to a seals meaning the motor could have been spinning slightly slower. #2 I was using a different Vane on the same anemometer. The weirdest part to me though is that the S10S and up line produces more flow with a fan with fewer blades. In a way it makes sense though the outer part of the fan is going to reach the highest speed and on the old ones the highest point is towards the center with the new one the peak is towards the outside of the fan. so that portion which displaces the most air is traveling the fastest on the S10S+ line.
