    FK1 Fireplace blower

    Posted by Warren Claassen on 18th Apr 2024

    Finally found this after searching for years. My house had been built without the blower in 1990 and ever since moving in in 2006 I have been looking for this. Well finally found it and it was priced for much less than expected. Since wiring was already there it went in quickly and moves a fair amount of air around the fire box. I will have to wait for next winter to really try it out but looking good so far.

    I have a fireplace with a small blower fan on each ducted side. I looked on the internet and found Turned out they had suggestions and equipment that would work and recommended the FK1. I am thankful they were willing to spend some time on the phone and internet looking at pictures and helping me come up with a solution. The parts arrived quickly in good condition packaged securely and saved me a lot over hiring someone to come out and repair it. It didn’t take long and works great. Thank you for your help in selecting a suitable replacement. Everyone was helpful and pleasant and I recommend this company.

    I reached out to the company on a Sunday, and had a reply back from Ross early Monday morning. Ordered & received the fans by end of week! Order process on phone was simple and guy I worked with was polite & easy to work with - Despite me being able to hear phone ringing like crazy in his background. The whole experience was AWESOME - I will keep this company in mind for future needs!! Thank You!!

    FK1-FK2-1CFMS-4Inch Blade fan Replacement

    Posted by Al Griffin on 16th Nov 2021

    Motor and Fan were perfect fit replacements for existing fans & motors. HOWEVER I had to transfer existing LONGER Mounting screws from the old motors to the new motors. To do this I had to tap the holes all the way through. I also had to replace the male spade connectors with female spade connectors. The wires could have been an inch or two longer to aid with the installation of the second fan further from the terminal strip.
