Good Morning Forum Members, I am looking to purchase a backup combustion blower and i have two choices. First Choice: http://www.cshincorporated.com/product_info.php/products_id/168 Second Choice: http://a1stoves.com/breckwell-combustion-blower-p-674.html The second choice looks like the one in my stove along with the attached image. Which one is better, the sealed bearing model or the one currently in my stove. My Concerns are noise levels from the blower, if anybody is familiar with either blower and maintenance required for both other than lubing the bearings which i am familiar with during times of tuneups. My stove is 3 years old, and the bearings started making a grinding noise, i lubed the bearings and the noise appears to be gone and running smoothly, I want to have a good backup in case this blower goes on me during the season. Thanks to all ahead of time.
