Spider Farmer 4 Inch Inline Duct Fan with Temp Humidity Controller, 205 CFM

I have a couple competitor fans that are of similar style, they either run full speed or have an analog turn dial speed controller, all are 4", I'd say the Spider at 50% puts out almost as much air as the others on full speed. I'm using it to pull air from a server rack, my temporary installation of the fan, it's a bit louder than it should be because of my ducting on one side and the lack of it on the other, plus it's 22" away from my head. Back to the controller, I like how you can can control lights, vent fan, blower fan, not that I'm using the others, but it's nice it can be done from one spot. I'm doing it by temp, I set 40% always on speed and a ramp up to I think 60% above 28C. Once it's in final home I'll tweak the settings a bit more. If I had to list 2 "wishes". 1. i wish I would have gotten the model with the mounting cradle vs the sling. 2. I wish the fan ramp up was more of a ramp up, like a PWM in a computer where ok it's at 40% and 24C, oh it's 25C now, lets ramp up the fan a little to say 45% to see if it'll bring them temps back down rather than wait til 28C and instant full 60% or 100% if that's what you set it to.

Lite för svag men klarade enkelt 80x80x180

Alles bestens, auch vom Support von SF, auch top Leistung. Mir bei den technischen Defekt sofort geholfen. Würde sogar nochmehr Sterne abgeben.

el producto ha llegado con la pantalla del control de temperatura con varias rallas

Excellent blower fan to handle 3x3 and 2x2 tents with ease. GGS controller and smart phone app utilization makes control a breeze. There are a lot of power level settings through the smart phone app, as well as timer cycles, humidity/temperature cycles, etc. Options galore! I’ve been running my first fan for several runs and performance is A+. Thanks, Spider Farmer!
