| #1 | Q: Regarding the TD-150S: What variable speed controller do you sell that works with this unit? A: 5 amp speed controls such as the Fantech WC 15 or IPF05 will work. Also the SP 2525.5UL. https://www.hvacquick.com/products/residential/AirFlow-Boosting/Exhaust-Fan-Controls Asked on 2023-05-31 by Home_Tuner |
|---|---|
| #2 | Q: Does the TD-150S already come with a plug or do I have to put one on it? A: None of the TD fans come with a plug/cord. You can attach a cord or hardwire them. Asked on 2022-02-02 by Dave |
| #3 | Q: TD-200S: 500 cfm in a 8 duct is 24 f/s velocity. Wont this be very noisy away from the fan and at transitions? A: 8 inch inline fans range in CFM from 400 to 800+. The 530 nominal CFM is quite typical. These are normally paired with flexible insulated duct to attenuate any noise coming out of the fan. Asked on 2019-07-10 by Richard |
| #4 | Q: Is the TD125-XS a two speed or single speed motor? A: The TD125-XS is a single speed motor. You can use an external speed controller (not supplied) to vary the speed if required. Asked on 2018-01-16 by Bill |
| #5 | Q: How many CFM does the 100XS move? A: Depends on the static pressure. The nominal CFM is 203/108 cfm (high/low). Full specs are on the Specs tab or in the PDF catalog. Asked on 2017-01-19 by RAB |
| #6 | Q: Can the polarity be changed on these fans to reverse direction for summer / winter operation ? A: No. The fans are one direction airflow only. Asked on 2016-11-10 by Donny |
| #7 | Q: TD-100XS just purchased would like to wire to a plug does it need a three prong or two prong? A: 2 prong is fine. These fans are double insulated and do not have an external ground wire. Asked on 2014-09-28 by CH |
| #8 | Q: Can these fans be used to boost the air duct supply air? A: Yes they can, typically this is done with a current sensor at the AHU or a pressure switch in the duct. Asked on 2014-08-26 by MS |
| #9 | Q: Can these fans run constantly 24/7/365? If or if not can they be placed on a humidistat? Which humidistat do you recommend?
Thank you. A: They can run continuously, and the Fantech FH20 Humidistat would do just fine on these or any of our units. Asked on 2014-06-20 by www.Aquatic-Interiors.com |
| #10 | Q: Do you have a scone rating for the S&P TD 100XS high and low speed? A: It is similar to the 150, low to mid 50s in dBa. Asked on 2014-02-23 by Bud |
| #11 | Q: Do you have a scone rating for the S&P 150S 4 on high and low speeds? A: No sone rating, bit it was measured on an open table when we first received them and gave a mid 50 dBA rating. Asked on 2014-02-23 by Bud |
| #12 | Q: What air temperature will the TD-Silent 150 handle in the duct? Would you recommend rigid duct or flex? A: The max air temp for this unit is 140 degrees F. Asked on 2014-02-22 by Joe |
| #13 | Q: Can this use a pressure switch? I do not want to add any switches to turn this off and on. It needs to start automatically. A: Yes, you can use a pressure switch on this unit, we like the Tjernlund PS1503. Asked on 2013-12-26 by bob |
| #14 | Q: Can this be used in a 6 exhaust duct for a stove/microwave? The fan will be in the basement, 15 ft. away from the stove which is on the first floor. A: It is not recommended to use these for kitchens as the baffles in the fan will plug with grease. Asked on 2013-12-06 by OBSAND |
| #15 | Q: Can the TD-Silent Series be mounted in an unconditioned attic? A: Yes it can, you may wrap it with insulation to minimize condensation, but that should be minimal as the unit is mostly plastic. Asked on 2013-11-25 by Micah |
| #16 | Q: If I use a speed controller to feed the fan, will wiring it to high speed give me its full range of speed ? in other words is the minimum speed the same for both slow and speed wiring ? A: They are in fact 2 sets of windings with different output levels so, yes, the bottom end will vary between the 2 speeds. Also, the effective range you would get on high or low speed will be about the top 40% of actual operation..any less and the fan would not have enough power to sustain running itself. Asked on 2013-11-19 by Guy B |
| #17 | Q: Can I use this instead for dryer boosting? A: Not the silent series, the lint would plug the baffles quickly and become a fire hazard. Asked on 2013-09-15 by Anthony |
| #18 | Q: Is a 220v-230v model available? Or can a variac be used? Im in new zealand?
Cheers A: We only have 120v/60. Fantech AU is the same thing but in your local voltage of 220/50. Cheers! Asked on 2013-07-20 by Wal |
| #19 | Q: What are the max db levels on the 6 and 8 A: We tested them at mid to high 50s...The baffles take the high frequency out so it does sound quieter than it is. Asked on 2013-07-01 by Streetfrog |
| #20 | Q: can you put a outlet plug on unit if so what are the specifications A: A plug can be put on, 14 gauge wire would be more than sufficient. Asked on 2013-06-04 by mas |
| #21 | Q: Can these fans be used with a speed controller? What type of controller is recommended? A: They can be speed controlled, something like the WC15 would be fine. Asked on 2013-06-01 by David |
| #22 | Q: How much does the TD-150S 6in inline fan weigh?
Thanks! A: 13 Pounds... Asked on 2013-04-24 by Chris |
| #23 | Q: Does the td100 come pre wire? A: No it does not. There is a wiring box o n the side for romex or a service whip. Asked on 2013-04-24 by phil |
