ostberg inline fan NICE!

Just got my new fan in and talk about quiet! Its about the same as a regular box fan on high maybe even a little quieter. Badass blowers are actually made by ostberg its the same just re badged and at a higher price tag mine is a 487 cfm i got a steal at www.hvacquick.com 126.44 shipped took about a week to get here and no damage. Plugged her in and i was surprised at how quiet it is i imagine a higher cfm would be louder but judging by the quality of these fans i bet they are quieter than any other og its kind.ill post pics later

Is it 4" or 6"?, do you have a carbon filter in your system? looks good, similar to what I'm looking at only fan/carbon filter combo at Lumigrow.com

Its a 6" and yes these fans work better with a filter and ducting they were made and tested just for that do a little research on them. Screw can and vortex hydrofarm all that bs though the hydrofarm is pretty cheap theres not much of a dif in price rven with the valuline or hurricanes and u get a better product and more cfm with ostberg. I recomend phresh filter too they work best.
