Fantech RVF and RVF EC Exterior Fans

The RVF models are exhaust-air fans for installation on external walls. The unit consists of an impeller with backward-curved blades and a casing in galvanized sheet steel with a white powder-paint coating. When installed on an exterior wall, all ambient noise is kept outside.  The EC-motor version provides the highest energy efficiency, can be speed controlled via a 0-10Vdc signal, and also includes a pre-wired speed control potentiometer.

  • Galvanized steel housing features powder-coat finish
  • Fan can operate in high moisture, lint and dust laden air
  • Permanently lubricated sealed ball bearings
  • Five-year factory warranty
  • Energy Star, HVI certified, cSAus, cULus

#1 Q:   RVF8XL and SWF-200, which is a better choice?
A:   Very similar performance. Both quality fans. The only real difference is that the SWF has a built in backdraft damper.

       Asked on 2022-01-22 by MT
#2 Q:   Do the rfv fans need to be on a gfci circuit per Fantech the NEC?
A:   It does not have to be wired to a gfci to operate but depending on what location its serving (wired to), it might need to be such as wet locations.

#3 Q:   Can you Recommend a range hood big enough to work with this Fan it doesnt look like the one you offer is big enough. Where do I install the silencer? Do I need access to it to service it? I live in the north so the winters get cold.
A:   The Fantech liners can accommodate any of the RVF fans including the RVF 10XL. The silencer is mounted anywhere between the liner and the fan (attic, crawl space, etc). You might want to give the duct and silencer some slope towards the fan in case there is any hint of condensation from the cold. The silencer does not require any service.

#4 Q:   Can the RVF6XL fan be mounted horizontally under a cantilever, i.e. duct oriented vertically?
A:   Not a typical application, but yes it can be mounted like that. Make sure the unit is well protected from weather/water as it should not be exposed in the horizontal orientation.

       Asked on 2020-10-01 by Bob
#5 Q:   Can these exterior fans be installed in a climate that freezes in the winter? I live in New York.
A:   Yes, they are rated for your temps and are installed quite often in the north east.

       Asked on 2020-05-22 by PCM
#6 Q:   What is the distance between the bottom of the unit and the bottom of where the duct would connect for the 8 and 10 models?
A:   Approx 3-1/16 inch for the 8 inch unit and 4-1/8 inch for the 10 inch unit. See more dimensions here:

#7 Q:   What decorative wall grill for a kitchen application do you recommend? Does thus unit require prefiltrering of the grease etc ? Or is there a built in filter?
A:   This is a fan only. No grease traps or filters built in. If you want to use a grille as an intake (as opposed to a hood) we would recommend a metal return air filter grille where you can insert a metal mesh filter to catch any grease.

#8 Q:   Does this fan come in different colors? The fan would be mounted via 6 duct on an exterior wall approx. 10 ft. above the kitchen hood. How can a backdraft damper be installed?
A:   They come only in white, but likely could be painted to match the exterior of the home... Backdraft would be done in the pipe somewhere between fan and hood.

       Asked on 2015-03-08 by paul
#9 Q:   Does this fan have a back draft damper, if so how is it operated?
A:   No backdraft damper on this must be installed somewhere in the line.

       Asked on 2014-04-07 by David
#10 Q:   What is the sone noise level rating of the 2 - 4 inch RVF units? Thank you.
A:   There is no sone rating available as it depends on installation. with some ducting and distance they can be very quiet, alternatively, they can be quite loud if they just are open to a room.

       Asked on 2013-11-19 by Roger - Canada
#11 Q:   Due to house design restrictions I need to install on the outside of the attached garage, venting through the attic will be approx. 20 feet from range to fan. Will there be noise at the range end. Should I upsize the vent piping to 5 inch because of length. Thank you
A:   With that distance noise should be minimal, a silencer will always help as well. Would be advisable to run 5 inch to get maximum effort at the kitchen.

       Asked on 2013-11-10 by Roger, Canada
#12 Q:   In a straight, through the wall installation, how do these fans rate for noise?
A:   If there is only a grille on the intake right through the wall, the noise will be fairly noticeable. The larger the fan, the more noise it will make...typically that scenario is done when no other alternative is available.

       Asked on 2013-09-22 by Michael G
#13 Q:   Can this fan be controlled by a variable speed switch?
A:   Yes it can, make sure the switch is motor rated and has sufficient amp capacity for the model you choose.

       Asked on 2013-06-20 by Norm
#14 Q:   Is this a kitchen exhaust fan? Can it exhaust the air gathered in a kitchen hood?
A:   Yes it is indeed a kitchen fan. We do recommend a silencer to keep the sound level down.

       Asked on 2013-05-29 by Jacob
#15 Q:   How do I feed power to this fan? It there a cord on the outside?
A:   There is no cord on these, they accept a conduit on the back of the unit from the house power supply.

       Asked on 2013-04-04 by Quin
#16 Q:   Can these vent direct through the wall? I was thinking of putting a grille on the other side of the wall for my basement bathroom...
A:   They can vent through the wall, however due to no room for any attenuation device, it will be louder than most folks would like.
