| #1 | 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. Asked on 2020-09-04 by VINCE |

| #2 | 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 Asked on 2019-12-02 by Joey |
| #3 | Q: Is there a internal wire chase in the 5DDU series fans? A: There is a tube conduit internal that acts as a wire chase from base to motor. Asked on 2019-10-31 by Ernie |
| #4 | Q: I am interested in the 5ddu13 upblast. What size duct do I need? A: It goes over a rectangular base (roof curb). Sizing is on the Specs tab and installation manual. Cap dimensions are 22x22 inches. Asked on 2019-10-16 by JJ |
| #5 | 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. Asked on 2019-06-27 by Tom |
| #6 | 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. Asked on 2018-03-04 by MA |
| #7 | Q: Can the 5DDU series fans be mounted directly on a 3/12 pitched roof without a roof jack? A: No. Its designed to be curb mounted. Asked on 2017-05-08 by Doc |
| #8 | Q: Im interested in purchasing the 18 size of this fan. Is it available in 230v? A: Yes, that is a dual voltage motor so it can operate on either 120/230 VAC depending on how it is wired. 1 phase. Asked on 2016-09-02 by Adam |
