|#4||Q: Can these fans be used to boost the air duct supply air?

|#5||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?

|#10||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.

|#11||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.

|#12||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.

|#13||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.

|#14||Q: Is a 220v-230v model available? Or can a variac be used? Im in new zealand?
A: We only have 120v/60. Fantech AU is the same thing but in your local voltage of 220/50. Cheers!

|#15||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.

|#16||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.
