Customer Questions & Answers

the duct is NOT 4 inches - What is the correct size pipe or adapter to transition to use the 4 inch duct pipe I already bought from your store?

where can the correct size adapter be bought to make this usable with the 4" pipe/ducting I just bought and cut and put in the attic for this wrongly described item?
Asked by: youwantaname
The O.D. is just under 4 inches, you should be able to clamp or tape the 4" duct over it.

what is the cost for installation of a exhaust bathroom fan

what is the cost for installation of a exhaust bathroom fan
Asked by: diane
To many unknown variables. Are you looking to replace and existing fan or is it a completely new installation? Is electric readily available? If not how far from an approved source or from service panel? Is there room in your panel for an additional breaker? How high is the ceiling, Is there access from the area above the location of the proposed installation? IE: attic? How far will the duct need to be run and will it penetrate the roof or the side wall (siding, brick, etc)

Rated 3 out of 5 by from Read this before you purchase. I purchased 2 of these fans to replace the pre existing 50CFM builder grade fans that have 3" outlets. I replaced the ducting with 4" before installing the new fans. The instructions do not tell you that you have to make an additional cut out in the sheetrock for the round shaped side top of the housing to fit. This leaves a large gap between the housing and sheetrock. Otherwise when installing the fan from either below or above the housing will not fit into its bracket. This is due to the bracket design which requires you to install the fan over the lip of the bracket first, and then tilt it upwards until it makes an audible click, snapping into the bracket. The direction my ducting was routed in relation to the bracket made this even more difficult. This is because I had to install the bracket on the same side as the outlet. It can be installed on the opposite side, but that wouldn't have worked for my install. If you are installing this fan in new construction, before the sheetrock than the additional cut out wouldn't be needed until time for replacement. With that said this fan is designed more for new construction, despite the unique bracket design. The instructions need to be revised by someone who has installed the fans before. The 4" outlet adapter sticks out several inches from the housing. With no access from above, this makes installing the fan housing into the bracket difficult. Especially because you have to attach the ducting before you install the fan into the bracket. Be careful not to cut the hvac tape, (breaking its seal) on the sharp edge of the bracket while trying to install the housing. It's a tight fit from below and you have to slightly bend the bracket upwards with your hand to get the outlet adapter/ducting to clear the bracket. Once you get the housing onto the lip of the bracket this is when you must trim off an addition 1/2" or more of sheetrock to bring the housing flush with the ceiling. Now the housing must be tilted down so you can reach up into the ceiling and bend the bracket back to it's original position. Otherwise the housing won't lock securely into place. Another install tip is that the fans 4" outlet is removable with a large flat blade screwdriver. Locate one of the two tabs on the side of the housing and slide the screwdriver tip between the outlet adapter and the housing. Gently twist or push the screwdriver just enough to release the tab and pull the adapter away from the housing. I only did this when installing the fan from the attic side. I did not find this information in the instructions. I just didn't think of it when installing the fan from below. I installed the other bath fan from inside the attic. Even when installing the fan from above I still had to trim additional sheetrock where the housing is rounded near the top. When installing from above, less sheetrock needed to be trimmed. I installed the bracket perfectly flush with the sheetrock as per the instructions. The fan housing is not level/flush on all sides of the sheet rock. This causes the fan grille to not be flush against the sheetrock. I think this may be due to the flimsy thin metal bracket or it's possible that the ceiling truss I mounted it too is slightly twisted. I may have to shim the bracket or move the bracket upwards 1/4" and re drill the holes to compensate for this. If the holes in the bracket were slotted this would allow for depth adjustment and resolve this issue. I also like how the fan housing is constructed of thick plastic and mostly sealed. Caulking or HVAC tape can be used to seal the small openings around the wire punch outs and electrical access cover. Compared to other brand fans I have installed, that were rated at even higher 4.5 scones. This fan seems to be louder than it's advertised rating. I intentionally picked a louder fan for more privacy in the bathroom, and so I know that it's on so I don't forget to turn it off and waste energy. The fan moves vents a lot of air and serves its purpose well. I hope this information helps someone make an informed decision, or install their new fan.

Rated 5 out of 5 by from Excellent value on a quality, versatile bargain! This is a vastly underrated high quality product that currently offers the most excellent value for money on the market if it's installed carefully and properly specified and equipped for the full range of it's uses. First of all the 70, 110 and 140 cfm Air King fans are virtually identical high tech very quiet and solid units except for power improvements in the motors and fan assemblies. This means that the very respectable and quiet 70 cfm @ 1.5 sones (or better) is available in all three models, all you need to get (even) quieter operation in the more powerful fans is a separate $45 fan speed control (dimmer) instead of a plain wall switch. Adding this external speed feature not only makes them virtually inaudible for everyday uses, but makes the stronger two versions versatile all-around price/performance winners . I have one of these in my main bath and a very expensive $200 80 cfm @ 2.5 sone "designer" metal klang-box Nutone fan/light in my powder room (which I'm sorry I bought) and though the motors/fans are very similar, there is no comparison, the soiid plastic Air King 140 is way better and quieter than it'll ever be with lower hum and vibration at up to 100 cfm speeds! For mere bathroom odors, a 20-30 cfm setting saves lots of heat or air conditioning energy and makes the BFQ140 totally inaudible. Only a speed control can offer you such everyday energy saving versatility. The size of the room and the total area of it's steaming water surfaces are the critical HVAC issue you must address with your ventilation device choices, noise is really a rather secondary consideration when you're having a long, hot shower, anyways.. A 70 cfm fan is well suited to a tiny, steaming (6 X10) 60 sq foot bathroom with a shower wetwall stall or perhaps a standard tub/shower wetwall which is air conditioned or used in cold weather. Such a tiny bathroom would be well served by a conventional 50 cfm unit in summer, as would any little 2 piece lavatory/powder room. 80-90 cfm fans are suited to normal 70-80 sq ft 3 piece rooms without whirlpool/bubbling spas. A 110 cfm fan is suited to a larger 90-100 sq foot bathroom with more "standing water" use like a small spa/tub and shower, you might get away with 90 cfm in spring and fall weather in such a room. If you have a large two person, corner spa (lots of water surface like 2 tubs plus air bubbles) plus a shower stall wetwall (+ another half a tub) and a 90-100+ sq foot bathroom you need 140 cfm if you have air conditioning and/or in winter months - you may get away with only 110 or 80 in less demanding situations, but when all the fixtures are in use (eg you have a daughter) there is no substitute for a 140 cfm fan -period! The laws of physics being what they are you cannot move 140 cfm of air through a 4" duct and grilles without making some more noise than moving 70 or 100 cfm of it. Spending a mere total of $90 on a Air King BFQ 140 and a fan speed control to regulate it's sound level and power for the situation at hand gives you the best of all worlds performance and versatility at way less than the price of the 100 or so cfm "state of the art" competitors. Adding some rubber pads to the motor bracket screws and under and between the "clip on" bracket and plastic housing and a rubber outer hole gasket (use thin rubber shower stall membrane) will further reduce the sones of this fan by 30% - also pay attention that the fan is squarely attached to the shaft (not wobbling) on it's mounting spring. This is really the air "king" of fan deals.

Rated 1 out of 5 by from Not accurate - Not 4" not 3" after a major struggle installing this odd hanger thing. the duct is Not 4 inches as described/listed after trying to fit a 4" fitting - there was room enough for my fingers in the gap [with gloves on] sadly a 3" fitting will not go over it either as it is just over 3 inches. they should WARN you that it is some Strange/odd size that you will not find in the stores. I cant tell if it works or not. it wired easily, but without being connected to a duct pipe going outside. it is totally useless. perhaps the correct size duct pipe and fitting can be bought somewhere else? Most likely I will need to manufacture an odd sized duct fitting for this to transition to the 4" Pipe I already bought and installed in the attic. Just be very aware that you Must make your own fitting to use this fan. I wish it worked as advertised. instead I am 70 miles from a depot store and am up the creek. . .

The fan housing is too large to install through the ceiling output tube even if you remove the (per instructions) unless you make the hole larger than the base, which would leave gaps around the fan. I called Air King support, who told me it needs to be installed from the attic, but you must "really bend up the mounting bracket to get it in". This will work, but then the bracket no longer holds onto the top of the fan housing. I'm returning it for another brand.

Rated 5 out of 5 by from AWESOME! -Air King 120 CFM Bath Fan This is a fantastic bath fan! I am impressed with how much air it moves. It was easy to install and is quieter than the standard "Builder grade" fans that come with typical new homes. It's not going to be as quiet as a 1 sone, but definitely is a good balance between power and quietness. I have this installed in a basement bathroom with no windows and a large shower. Needless to say it removes shower steam quickly! (and odor too...) Very glad I purchased this fan, plus this one is more powerful and cheaper than the units available in the stores. Buy it, you will love it!
