S&P SWF sidewall fans
The Sidewall Fan Series (SWF) of direct drive centrifugal ventilation fans consists of five model sizes ranging from 4 to 8 inch. All models are designed for direct connection in-line with standard diameter round ducting. Airflow performance values range from 119 CFM up to 416 CFM. Each unit also has a built-in spring loaded backdraft damper!
The SWF series utilizes the same powerful (high static) motor found in the popular PV Series fans, yet the SWF series is encased in an exterior mounted housing. The outdoor rated exterior housing provides easy access from the outside of a building or dwelling. This makes the SWF a great solution for installations where attic space or easy indoor access is difficult and not suitable for traditional PV style in-line mounting.

| #1 | Q: Hello, I want to replace a wall-mounted Broan-NuTone 509 (8 vent) with a quieter unit. The application is for a powder room that does not have a shower or bath. My questions are:1) Is an S&P SWF sidewall fan a suitable replacement?2) What is the Sones rating for the S&P 8 SWF sidewall fan? A: The SWF series is meant to be paired with insulated flex duct to a remote intake grille for sound control. If you install it as direct exhaust through the wall it will not be quiet. S&P does not publish sone ratings for this fan because its installation dependent (how much flex duct you pair it with). Asked on 2024-09-07 by AF |

| #2 | Q: For a Fantech HL36 hood liner, it appears from the spec chart that a 6-duct RVF 6XL will flow more, 338 CFMs, than an 8-duct RVF 8XL, 321 RFMs. If those numbers are correct, is there any advantage to using the RVF 8XL in this instance? Thank you. A: Our recommendation is always to stick with the same pipe size as the liner if possible. Not sure how Fantech rated these 2 fans with the HL36 but they do have the same motor so it makes sense the performance is so similar. Typically reducing to 6 inch does have a negative effect on the CFM of the system. Asked on 2024-01-07 by STC |
| #3 | Q: can this swf be powered up on a 24/7 basis? How do you size up fan for room size in correlation to square footage? A: Yes, these fans can be powered and run 24/7. Sizing depends on the application -- call us and we can go over your application. Asked on 2023-11-23 by bradly |
| #4 | Q: can you tell me what the decibel rating is on this product? A: S&P does not publish sound levels for these remote fans. In our experience these are quiet when used with 8 of more feet of flex insulated duct. Here is their official statement: At this time there are no sone level test standards available through HVI due to the fact that remote mounted fan noise levels are in proportion to the following: type of duct, length of duct, fan distance from the intake source and other random factors. It is generally accepted that remote mounted venting is quieter than standard (in room) venting. Asked on 2023-09-08 by tomah |
| #5 | Q: Can the duct collar on the back be cut down for direct connection to a diffuser on the opposite side of the wall it is mounted too. A: The backdraft damper is part of the collar so you would loose that. Not advised. Asked on 2023-07-20 by Francis |
| #6 | Q: What is your quietest fan recommendation in this configuration? A: The Fantech and Soler Palau fan are similar noise levels. They are meant to be used with a section of insulated flexible duct to take out any noise generate by the fan. Asked on 2021-05-13 by Papa |
| #7 | Q: Can SWF150 or 150X be mounted on roof?It will be short straight run of about 1 foot through flat roof , no elbows A: No. Its meant for sidewall (vertical) mounting only. Fantech RE fans are meant for roof mounting. You might need a curb if the roof is flat: https://www.hvacquick.com/products/residential/Kitchen-Exhaust/Kitchen-Exhaust-Fans/Fantech-RE-fans Asked on 2020-08-07 by Gregory |
| #8 | Q: In your Q & A (#13) you claim your fan can be used in the kitchen but fans designed for kitchen use are typically supplied with a sealed motor to minimize the chance of a fire from grease and oils getting into the motor. Are the SWF-150x or SWF-200 rated for kitchen use? Thanks. A: You might be confusing rules for commercial and residential kitchens. You should never have a lot of grease in your residential kitchen duct since its not designed to be steam cleaned like a commercial setup. Yes, the SWF is rated for residential kitchen duty. The motor on these it totally enclosed and designed for all residential duty. Asked on 2019-09-16 by Steve |
| #9 | Q: I live in Alaska which experiences extremes in both sides of the weather, 90+ deg F and -30 deg F, how well would this hold up? A: We sell these in all states. The temperature range would not affect it as much as water and snow exposure. I would suggest keeping the fan out of the elements as much as possible to keep the casing looking good in the very long term. Asked on 2019-07-08 by Louis |
| #10 | Q: Would this fan be a good choice to exhaust hot air from a garage? I live in S.W.Fl. If I run the fan 4 hours a day, what is the life expectancy of the motor. A: Sure, we see this application all the time. Same motors are used in the radon fans and they have a life expectancy of around 10 years running 24/7, so very long. Asked on 2019-04-17 by Jim |
| #11 | Q: Looking for a very quiet exhaust fan. Exterior surface mount on exterior wall of office or cieling mount with duct work to exterior. Needed to exhaust cigar smoke out of office which is approx. 140 sq.ft. Any recomendations ? Thanks A: This would be a good choice of fan, I would still try to use flexible insulated duct to help assist with sound. One of the 6 inch models should provide good extraction as well as keep sound reasonable. Dont be afraid to put a decent run of duct as well, this will pull it easy, and that will help with sound. Asked on 2018-12-17 by JRL |
| #12 | Q: In which direction(s) is the exhaust air discharged? A: The exhaust path is downwards. Air comes in the round opening on the back side, into the black/white enclosure and pushed down through a louvered opening. Asked on 2018-12-12 by Bill |
| #13 | Q: can I connect the exterior fan to my range hood power so one control operates both? A: Most likely not. Typical range hoods have 2-4 speed controls for their motors while the Fantech fans require variable controls (not stepped speed but full speed variability). Feel free to call us with further questions. Asked on 2018-12-01 by Mike |
| #14 | Q: Does this fan have a thermostat? Is it possible to set the thermostat? A: No. This is a fan only. You can control the fan either through a line voltage thermostat, a speed controller or a plain switch. None included. Asked on 2018-07-05 by Richard |
| #15 | Q: Can the exterior of the fan be painted? Thanks! A: Yes, you can treat the stock paint as the primer coat. Roughen up and repaint. Asked on 2016-06-27 by Terry |
| #16 | Q: Just to clarify, the only thing I need to cut through the wall is the round exhaust port? A: No, you have the duct hole and the electrical connection hole. Asked on 2016-05-31 by LR |
| #17 | Q: can this fan be controlled with a variable speed control knob? A: Yes, typical speed controls will work fine. Search for the WC 15 or SCD 5 on our site. Asked on 2014-09-02 by gary raney |
| #18 | Q: Does the back draft damper open and close automatically or does it use a rod/chain? A: It opens via airflow and closes by gravity. Asked on 2014-04-07 by David |
| #19 | Q: how do I turn it on? How do I mount this item? A: You would connect an electrical switch of your choosing for control...Mounting is accomplished bty removing the shroud and screwing the rear plate to the wall. Asked on 2014-03-27 by terry |
| #20 | Q: How quiet is the fan? The fan will be mounted directly outside the kitchen wall and I am using a nutone which is very quiet.... A: If it is going right through the wall, it will be fairly loud...These like some distance and/or some mitigation techniques to keep them quiet. Asked on 2013-09-16 by Bill |
| #21 | Q: This product is listed in the kitchen ventilation section but the installation manual says that it should not be used to exhaust air hotter than 140 degrees. So is this product OK for kitchen stove exhaust? A: It is fine for kitchens, the likelihood of the air exceeding 140 degrees in the pipe is quite low unless it is right at the stove.
