Question: Do you have a 325cfm duct fan in 6 andor can I use a 6 outside vent to end an 8 duct fan run? How much noise does it make in the wall?
Answer: On the Duct fan model EF-8 you can use a 6 inch outside vent, but that will reduce the air flow rate of the fan. So this fan would not be moving 325 cfm. The fan operates at a minimal sound level.
Question: What type of bearings? Can they be lubricated? Thank you.
Answer: The 8 Inch Duct Fan has sealed bearing so no lubrication is needed.
