Guten morgen, wie gehts!?
Am having to got to Harbor Freight tool supply to pick up one of these to regulate the fan speed of my new Value-Line 6" centrifugal fan.
*at Harbor Freight it's called a "Router Speed Controller", at the hydro shop two buildings away it's the identical unit but branded as a "Speedster Fan Controller" and costs 50% more.
It's dropping down to the upper-40's and lower-50's (F) at night outside, and is keeping my grow closet TOO cool during Lights On!
The warmest I can keep it is 74.8, and that's with un-coupling the cool air ducting from the window insert and using the "warm" room air, which also means any warmth in the room (also my computer/art/music room) gets sucked out the window and it drops down to 74f. Which is not "cold", but it cooler than it should be.
So, for $20 I'll be able to regulate the fan speed, and cut down on the "whooshing" noise caused by 435cfm being sucked through the duct opening of the light hood inside the closet. And will also be able to keep the cool air ducting attched, so it won't be drawing warm air from the room out the window anymore.
I'm sure our next-door-neighbor can hear it, as it's fairly loud.
This will also cut down on the noise that the fan itself makes, which is less than 5-ft away from my computer chair where I do my "work" all night long up near the ceiling and directly ported out through the window insert (I sleep no more than 4 or 5 hours at a time because of my back, so live my life like a cat and sleep when I can).
Will give a report on how well it works later today.
