Static pressure for dummies like me
No ducts, filters, or obstructions = lower static pressure
Ductwork, bends, length, carbon filter, and light goods = high static pressure
Axial fans used for lower static pressure
Centrifugal fans used for high static pressure, ductwork, carbon filter, etc.
Ive been doing research and trying to find people who have had similar interests problems with inline fans not pulling hard enough or fast enough to be effective at extracting enough air from my grow tent to keep temps down.
I bough a couple of those little 30$ inline booster fans 175 com from Home Depot to use as extraction fans. One 6 inch little duct booster fan without any ducting or filter like this......
.....does well enough by itself to move enough air to keep the temperature down. Then I hook up a tiny bit of duct to it and a carbon filter. Trash. My temperature shoots up to 86 Fahrenheit from 78.
I have looked around online before deciding and came to the conclusion that a fan like this.....
Centrifugal inline fan
.... will be able to do a better job moving air against static pressure caused by ductwork, bends in ducting, carbon filters, light hoods, or anything else that causes higher static pressure in the ventilation system than this......
Axial in-line fan
Or one of those silver ones that cost 30 bucks at the hardware store.
The axial fan is good for moving air if there is no duct work filter and low static pressure. The centrifugal fan is much better for moving air through ducting carbon filters and other obstructions. Similar to having more torque or more horsepower.
Is this conclusion accurate? Please answer if i am correct in my conclusion. Thank you.
