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:   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.

#2 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.

#3 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.

#4 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.

#5 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.

#6 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.

#7 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.

#8 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
#9 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.

#10 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.

#11 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
#12 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.

#13 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.
