For nearly a year, we have been searching for a solution to a noise being produced by a boiler fan that heats our kilns. You can read our initial post about the noise here. We finally have some good news to share. This spring, we located an engineering firm in the U.K. that specializes in designing fan modifications to reduce tonal fan noise, which was the problem we were experiencing. The engineering firm designed a custom solution for our fan, which we have implemented to reduce the offending tone. After more than a week of testing this modification, we are confident we have found the solution.
Again, we apologize to our neighbors for the noise disruption and thank you for your patience as we worked to fix this.
