I am a home train hobbyist. Built a shelve train track, that extends the inside perimeter of my 3 car garage. Also do home electrical wiring, lighting effects, and plumbing
A high quality, functional external kitchen exhaust fan.
I installed this as an external kitchen exhaust fan on my Condo (with HOA approval). This is in addition to the over the stove venting microwave that makes noise but moves insufficient air. Now I move 5 times the CFM with no motor noise in the kitchen. And the external noise at full throttle is moderate. My duct length is 20". I also installed Fantechs MPT-10 potentiometer that gives 0-100% speed control. Installation was straight forward with well written instructions and great tech support available by phone.
