Question: Can I buy smaller blades to make it a 45" fan?
Document: I bought this fan to replace an old one that had given up after 13 years service. The fan is very quiet and, with a couple of weights at the right places on the blades, is rock steady at all speeds. I like the multiple speed choices and the remote control is simple and works well. Happy with this purchase.
I have had many ceiling fans over the years and my biggest complaint has always been motor and bearing noise, especially when it comes to my bedroom.This fan runs cool and quiet at any speed. All you will hear is the fan blades pushing air. With so little heat being generated by the fan our bed room seems to always be cooler than the box store fan it replaced. love the 6 speed settings and the white finish looks great.
If your home has a second circuit for the lights on the fan, you will have to run separate wires through the center of the fan for the light kit but that was easy to accomplish. The six speeds, very quiet operation, and remote control make this fan a winner in my book!
We bought a similar fan for our kitchen last year and were very happy with it, so we ordered a second one to replace an old, VERY NOISY fan in our bedroom. These fans are well built, easy to install, and super quiet. If you don't look at it to see the blades moving, you won't hear it. The light kit and downpipe are ordered separately but easy to install on the fan motor.
The Casablanca fan far outclasses its competitors. I Installed it over my bed and put it on night before I go to bed. It is made sleeping so much more comfortable in the warm weather. It's absolutely silent. But I'm not surprised because it is the fifth Casablanca fan I've purchased over the last 20 years.
From then on you can change speed at will. But if you try to start (or reverse direction) on a low speed, the fan speed will &#34;hunt&#34; by speeding up and slowing down but will not settle on a steady speed. I know that speed control of a DC motor is more complicated than for an AC motor, but that seems like a marginal engineering design...
I bought this fan after a lengthy search and a couple of frustrating false starts, and am extremely happy with it. Construction, fit, and finish are  excellent; installation difficulty is the same as most other ceiling fans, and the instructions are clear and first rate. It moves a lot of air, and the motor and mechanism are absolutely quiet. The remote control is full-function, including forward-reverse.
The Casablanca product sheet says one is &#34;available&#34;, and I spent quite a bit of time trying (unsuccessfully) to find it; was very happy to see it in the box!
A very high quality product that meets my full expectations. Easy to install, well balanced, and attractive. I will order additional fans for other rooms,Howard B
