Can this be used as bathroom exhaust fan
Asked by: Bob227
Yes, it can be wired to turn on just as a bathroom exhaust fan. In theory the fan could be installed anywhere between the bathroom and the exterior of the home.

I want a duct fan that turns on/off with my furnace fan (i.e. not continuous), does this unit have that capability or is it a manual on/off only?

Asked by: Lars
Lars, I was in the HVAC industry for 19 years and here is what I would do: Install a receptacle on the furnace that is powered by the same control that turns on your furnace fan ( you may already have this if there is a humidifier installed). Then just plug the power cord into that receptacle, use the switch selector on the vent fan to choose high or low speed and you are all set.

Can this fan be used in a 4" duct to boost AC air movement

Trying to extend air thru a wall
Asked by: MrCarl
MrCarl, In my experience a 4" A/C vent is too small. Although this fan will act as a booster, the simpler solution would be to use larger duct pipe. Even going up to 5" will greatly increase air flow and if possible a 7" oval pipe would greatly improve the CFM delivered to a room. Although it is a bit more work, it will be cheaper and work without electricity.

Customer Reviews

VENTS 105 CFM Power 4 in. Mixed Flow In-Line Duct Fan is rated 4.5 out of 5 by 36.
Rated 2 out of 5 by from Too Loud! I bought this fan based on reviews that said it was quiet, which is also explained in the item description. I also installed a muffler, which quieted the air flow, but the fan itself makes a low hum that can be heard easily throughout my room. I tried to isolate it from the ceiling joist to which it was mounted, at which point a vibration could be felt, but it only helped some to suspend it. My application is for ventilation in a recording studio, I have a mini split system for heating and cooling, and have a separate ventilation system to bring in fresh air. I'll be searching for a quieter fan, which will certainly cost twice as much if not more.

Rated 5 out of 5 by from WHAT TO EXPECT I've not installed this yet so this post is about informing you what to expect. From the description and single picture I had no idea and took a total chance on this. I'm doing HD's job here and informing you. CORD: Mine came with an 18ga 8' SVT. Plenty long enough to be useful, not too stiff to work with. NOISE: I can hear it, but that's all I can say about that. I would in no way characterize this as loud. I wouldn't call it quiet as an absolute, but in comparison with nearly every bathroom fan I've ever heard (my intended use), yes, it is quiet. The shaded pole motor is 'bumpy' and the rotor seems to be not very well balanced (it is low RPM, so that's fine) so I could see how this would cause vibration noise if mounted rigidly to wall or ceiling panel that would then act like a giant speaker or to a structural member so the vibration is transmitted throughout the house. I intend to mount it on rubber pads to isolate vibration and to have a flexible coupling (duct tape) at the ductwork rather than screwing the duct to the nozzles. Noise will be a non-issue. In fact, I expect it to be nearly silent given its use and location. SPEED: It has a two speed rocker switch configured I-0-II. Upon opening it up it appears it is a two-speed wound motor as the line input goes to the switch common and the two speeds go to the motor along two wires. I didn't notice a resistor anywhere. The rating on the side of the motor specifies 2818 RPM and 3113 RPM, though these numbers might not mean much as you'll see. POWER: As soon as I opened the box there is a bright orange bulletin under the flap that you see before you get to the product telling you about speed variations. It states that as the line losses increase the motor speed will increase to compensate and in the case of low line losses or stand-alone table-top operation off any lines at all the RPMs will be low. I experimented with it and this appears to be true. I occlude part of the intake or exhaust and the RPMs ramp up. Pull my hand off and it slows way down. I opened up the unit, including removing the motor from the housing, and there appears to be no flow or pressure switches or rheostats. My theory is that the power of the motor is so close to the edge of the requirements of the design that it becomes self-regulating. The fan blade has 1/8" clearance from the shroud, the frontal area of the rotor is 100% of the swept area, and the angle of attack on the blades along the unit's longitudinal axis is rather aggressive. I believe that when the fan is unhindered it is all the motor can do to push the rotor through the air and will push the rotor until it reaches its 'power:load equilibrium' before reaching its rated RPMs. If the airflow is restricted through occlusion or line losses the mass of air it pulls is decreased and the load on the motor drops, allowing the RPMs to increase until it reaches equilibrium again. Full occlusion of intake or exhaust doesn't result in runaway RPMs because of the natural limits imposed by the 60Hz power source. All this being the case, be warned: this thing is operating at its limits. It will not perform well with high line losses, such as running 50' of flex duct or too restrictive grilles. It has to breath easy to perform well. Keep that in mind and it will work fine. Also, since its speed and flow characteristics seem to be limited by the mass of the air being moved then its ratings were probably obtained under some sort of favorable laboratory conditions and YMMV, depending on your local humidity, barometer, elevation, etc. CONSTRUCTION: I mostly like it. Other than the motor itself and misc hardware it is all plastic. The brittle kind, not the flexible kind, so there's a bit of a down side there. I doubt the thing survives a fall unscathed. Luckily the mfr included and extra set of collar rings. YAY! That was actually surprising and very thoughtful Excellent customer service there. They made cleaning very easy. The intake and exhaust nozzles are separate pieces from each other and the fan body. The nozzles have integral mounting plates for affixing them to a surface and then the body secures between the nozzles using retaining collar rings. (Pic 1) Therefore the fan body is easily removed from the mounting and duct work by simply removing the retaining collars; no need to unmount the unit from the structure or uncouple from the duct work when the fan needs cleaning. Super easy. The collar rings are secured with latches that can be screwed down to prevent accidental release. (Pic 4) It is this collar ring that you get spares of. Get something cock-eyed and I can see this stuff snapping easily. The collar rings anchor via simple hook and pin (Pics 7 & 6) whose lifespan is predictably short, thus the spares. The nozzles and body have flanges on them which the collar ring uses for purchase. (Pic 5). It occurs to me there will be pressure losses here. I might see if I can put a bit of sealant on those mating surfaces prior to assembly. The fan body flange has a groove that looks like it might have been meant to accommodate an o-ring, but it is a little shallow so I can't see an o-ring staying put. That'll be where I put a bead of sealant. I believe this unit is designed for low loss lines. The rotor (Pic 2) appears to be designed to accelerate air longitudinally and the anti-twist vanes (Pic 3) seemed to be designed to keep the air velocity high. It's meant to move free flowing air fast down a duct, not shove resistant air hard through a restrictive pipe. Flex duct is probably a no-no. Stick to PVC and rigid AL/steel duct for smooth laminar flow. Loooooong duct of any description and/or hard turns (elbows) is probably a no-no.

This fan was installed in a basement window for the purpose of venting an average size room on the first floor. It does the job well. The design of the unit, with removable motor assembly, mounting hardware and long power cord made installation very easy and allows for easy servicability in the future. The sealed motor housing and control switch is great for an application where humidity levels are high. Although the unit has a slightly higher vibration level than some others that I have used, I find it acceptable in this price range. All in all the design, features, installation and performance of this unit exceeded my expectations.

Rated 5 out of 5 by from Quality, price, performance I purchased this for use as an exhaust fan for my indoor grow tent 2x2x4 and it moves constant air flow over my plants and grow light keeping temperatures and humidity levels down. The 2 speed switch is awesome and sound at high speed operation is quiet. Very easy to install, disassemble and clean when needed. Will most likely be purchasing a 2nd unit in the near future

Rated 4 out of 5 by from Good fan This is a nice product, quiet, but it did not meet my needs in a specific application; I needed more air flow, although the fan did produce it's rated flow rate when measured on the bench. HD allowed me to return the item HOWEVER, information provided with the fan made a strange and incorrect claim. The information stated that the fan would automatically increase it's speed and thereby increase the flow rate when there was a restriction (like a long duct length) reducing the normal flow. No, the fan speed increases because it is moving less air. All fans will increase RPM when the flow is restricted, but not because they are increasing RPM in order to move more air!

Rated 4 out of 5 by from Well Designed Fan This well designed fan allows you to pull out the fan without disturbing the pipe connections. The only drawback is the buckle on the clamps that hold the fan in place. If you don't seat the buckle properly and try to close the clamp, it will break. It's as if the company knows this since they give you two extra clamps. Otherwise, great fan...quiet, easy to install, comes with a power cord already installed, and two flow settings controlled by a mechanical switch. Probably, a bit more expensive than other in-line fans, but the quality and quiet operation are worth the premium. I have two fans installed.
