#1 | Q: With the DB206C and DS100 installed into a 6 inch duct, can you recommend a powered damper that could open and close automatically? Open only when the blower is on? I have a garage that is not always heated or cooled. Thanks. A: You can use the Suncourt ZC206 normally closed 6 inch damper. Power applied to open the damper, spring close when power off: https://www.hvacquick.com/products/residential/Ventilation-Accessories/Air-Dampers/Suncourt-Motorized-Zone-Dampers Asked on 2024-01-22 by Mike |

#2 | Q: Can you use the DS100 with the VS200? Or do you just need one or the other? A: Yes you can. The DS100 would switch the fan on/off and the VS200 would control the speed of the fan once switched on. We normally see the fans used with just the DS100 in duct boosting applications. Asked on 2023-12-05 by C H |
#3 | Q: Do the fans come with the DS100, or are they to be purchased separately. A: The DS100 is purchased separately. Asked on 2022-10-10 by Bill |
#4 | Q: Can these be used to vent my dryer exhaust ? I will be stacking my dryer, is their a specified Distance the motor should be from the dryer. Where motor will mount its about 20 to outside. A: No. These are not rated for dryer exhaust. Take a look at our dryer boosters category. You will typically need a lint trap if the fan is closer than 15 feet from the dryer: https://www.hvacquick.com/products/residential/Dryer-boosting/dryer-booster-fans Asked on 2021-10-11 by Rick |

#11 | Q: Can the DS100 be installed on flex duct? A: No, you would not have any support for the stat. It needs to be screwed to a rigid structure and a hole made for air sensing. Asked on 2016-07-15 by Jerry |
#12 | Q: When these are off do they substantially block the regular blowers airflow? A: Not substantially, but they are an impediment. Asked on 2014-07-02 by Chuck |

Asked on 2013-10-16 by Kevin B |
#15 | Q: What is the voltage for the 10 inch Suncourt Duct Booster Fan A: It takes 110v and 1.5 amps. Asked on 2013-07-01 by Hal |
