#2 Q:   I want to use this fan to boost a supply fan duct system. What is the lifespan of the fan it is left running at full speed?
A:   Our experience with these motors in radon applications is 8-12 years continuous running duty.

       Asked on 2021-04-09 by Derek
#3 Q:   Can this be directly hard wired for one speed only?
A:   Yes, hard wire direct to a switch or thermostat for on/off, one speed operation.

       Asked on 2020-01-01 by Brandon

A:   It can be used to move warm/hot air around the fireplace to other areas. Max allowed airstream temp is 140 F.

       Asked on 2019-04-21 by Nathan
#5 Q:   How is the muffler installed with he fan and is an instruction manual available on line?
A:   The LD muffler/silencer is installed between the fan and the space you want to keep quiet. It replaces a section of duct. Installed inline. Fantech does not publish any instructions for it.

       Asked on 2019-03-04 by John
#6 Q:   The Fantech FG 10 shows a vertical mounting bracket, but I cannot find the part number or any body that sells the mount.
A:   The fan mounting bracket (vertical or horizontal mount) comes included with the fans that we sell. We do not sell it separately.

       Asked on 2018-11-12 by mark
#7 Q:   What is the maximum operating temperature for the air inside?
A:   Rated for airstream temperatures up to 140 F per the catalog.

       Asked on 2016-11-04 by David
#8 Q:   Are Fantech FG fans suitable for insulation contact installation?
A:   That would be fine with these fans as they get their cooling air from the air they are moving, as opposed to vents on the side.

       Asked on 2014-07-26 by Derek
#9 Q:   How is the the FG 6XL activated and deactivated once installed? Is it hardwired to the blower motor, to come on when that circuit is closed, or is there an upstream air pressure sensor? Thanks!
A:   As it sits, there is no must be added on or wired to the blower.

       Asked on 2014-06-30 by Jerry
#10 Q:   What is the fan wheel made out of aluminum or another type of metal?
A:   It is actually non-metallic per the factory.

       Asked on 2014-02-10 by rick
#11 Q:   How will the FG 6 XL handle grease and other residue? I intend to mount this unit so that it draws from the top of the cooking range. The unit I currently use requires acasional cleaning.
A:   These work very well for kitchen duty...I would recommend getting it away from the hood a bit for noise purposes however. If the screens in the hood are maintained, the fan should need little to no cleaning.

       Asked on 2013-08-31 by Carlton
#12 Q:   What is the noise level for FG 6 XL model
A:   There is no listed sound level as how the fan is installed matters quite a lot. Just open on the bench I would put it in the 70 decibel range.

       Asked on 2013-06-27 by Richard
#13 Q:   Can a person install a variable speed switch to increase or decrease speed of fan
A:   Yes, no problem at all. The WC15 or SCD5 have plenty of capacity to do that for you.

       Asked on 2013-06-27 by Richard
#14 Q:   is the fg 4xl explosion proof?
A:   It is not, by definition no inline fan could be as the motor is in the airstream.

       Asked on 2013-06-05 by Shawn
#15 Q:   can the FG series be mounted in vertical and horizontal orientations?
A:   They can be installed in any orientation, no problem.

       Asked on 2013-04-07 by Ed
#16 Q:   Can these run on DC voltage or is there a DC version?
A:   They could run with an inverter, but they are not currently available in DC.

       Asked on 2013-04-04 by SoCal
#17 Q:   Is there a backdraft damper built into the FG fans?
A:   There is no back draft damper on any of the fans, we prefer to install them at the penetration of the building envelope to stop the air from entering at all.

       Asked on 2013-04-04 by EF
#18 Q:   Should the fan be placed closer to the intake or closer to the exhaust cap? Or does it matter?
A:   These fans are equally adept at pushing and pulling, so place the fan where it is most convenient to mount and access in the future if service is needed.
