Allure 3 at 300 and 430 cfm discharge. Does this reduce motor life and performance?
Thank you for your question on the Allure 3 series range hood. You must use either 3-1/4” x 10” rectangular, or 7” round duct work on this unit. If you reduce the size of the duct work, you will reduce the CFM, make the motor work harder thus reducing the life of the motor and void the warranty.
