    4 blade blower fan and motor

    Posted by Eugene Brown on 15th Feb 2021

    I gave it four stars I would have given it five very nice quality motor well built runs fantastic love the quality of the work the reason I did not give it five stars is that the wires on it are just a little short I wish they were about five or six inches longer. I would recommend this part but keep in mind that you may have to splice wires to make it a little longer if your needs required.

    Noise Reduction

    Posted by Happy on 13th Nov 2020

    Very happy with this fan. Much, much, much quieter than the one I replaced. I don't notice any loss of air movement either. I also got the variable speed control which can virtually eliminate all noise if you don't mind reducing air movement.

    4 Inch Blade Fan Replacement

    Posted by Ryan Oakes on 29th Sep 2020

    I'm trying to get more heat flow out of my gas insert, and noticed there were 2, 4 inch fans in the back but room for 4. So I bought another 2 and added them into the existing wiring. It is really pushing out the air flow now and does a much better job of heating the room. The noise is slightly louder than before with 4 fans running instead of 2, but it is not bad. Really happy with how this turned out.
