Q: can model # 5ddu10aa be mounted on side wall and if so will curb still be required A: Yes, roof or wall mounting is fine. You will need some way to attach it to the wall -- the base needs to wrap around some structure whether its a curb or something else.

Q: Does it come with the base mounting bracket? And what is meant by curb mounted? A: It comes with the square metal section (see picture) below the round fan section that goes on top of the roof curb. See images in the accessory manual for examples of a roof curb: https://www.hvacquick.com/catalog_files/Fantech_Commercial_Accessories.pdf

Q: I have a 1970s belt drive fan on a 2020 roof vent. Will the 20 1/2 fit? I am guessing that is O.D. of cap flange. A: Not quite sure what a 2020 roof vent is. If its a 20x20 inch outside dimension roof curb then look for a fan with a larger A base dimension. There are 22x22 inch A dimension fans. Feel free to call with questions and we can go over sizing for you.

Q: Hi i am looking to purchase the 5DDU12ca, what would be this best size diameter duct to use at a 15 foot run. A: 14 inch duct at 1450 cfm is only 0.2 inch WC pressure drop per 100 ft of duct so very reasonable resistance. I would stick with that or larger, as space allows. Keep bends, transitions and elbows to a min.
