INVISIBLE ATTIC MOUNTED WHOLE HOUSE FANS FROM 11 INCHES UP TO 48 INCHES
Below are attic mounted systems I invented for special customers all over the US. The 11 inch fan was the first I sold in 2008 and I shipped 6 systems to Ebay customers and they ALL are still working today!
The first 4 below need only one duct because the most common ducts come in sizes up to 20 inches diameter and these fans are all 20 inches or smaller.
The IN1500 comes with straps to hang it from your rafters. It is perfect for one room. A 15 by 15 room with 8 foot ceilings has 1800 cubic feet inside. This will move all that air in under 2 minutes. You will be glad to know that I sold several of these to customers all over America in 2008 and they have all been very happy with the systems.
The IN2540 comes with straps to hang it from your rafters. It is perfect for a home that is 1000 square feet or smaller. A 1000 SF home with 8 foot ceilings has 8000 cubic feet inside. This will move all that air in under 4 minutes. But if you want to use it in a larger home it is easy to see that a 2000 SF home with 8 ft clgs has 16,000 SF so this will move all that air in about 6 minutes. (16,000/2540)
The IN3620 comes with straps to hang it from your rafters. It is perfect for a home that is 2000 square feet or smaller. A 2000 SF home with 8 foot ceilings has 16000 cubic feet inside. This will move all that air in under 5 minutes. But if you want to use it in a larger home it is easy to see that a 3000 SF home with 8 ft clgs has 24,000 SF so this will move all that air in about 7 minutes. (24,000/3620)
Here are 4 customers (Paul bought 2 for his home) that are all happy they bought these – amazing that it has been 11 years and they all work fine! Paul is on record to be happy to talk to anyone looking into new fans. Just ask me for his phone.
The IN4740 comes with straps to hang it from your rafters. It is perfect for a home that is 3000 square feet or smaller. A 3000 SF home with 8 foot ceilings has 24000 cubic feet inside. This will move all that air in under 5 minutes. But if you want to use it in a larger home it is easy to see that a 4000 SF home with 8 ft clgs has 32,000 SF so this will move all that air in about 7 minutes. (32,000/4740). Here are some customers who are very happy with their 4740. You can request their contact info any time if you want to ask them how they like it.
HERE ARE LARGER INVISIBLE FANS THAT OFFER YOU MORE DUCTS TO PULL AIR FROM MULTIPLE ROOMS.
These unique inventions of mine are the result of requests by customers who wanted more air flow but not the noise that ceiling mounted fans make. These are unusual especially because some had to be cut in two in order to fit up through the attic access hatch.
24 INCH 5600 CFM $1600
This fan did not need to be cut in order to fit through the attic entrance in the newer home it was built for because newer attic hatches are usually 20 inches square so the diagonal opening is almost 28 inches. This has 4 12 inch ducts connectors and comes with 100 feet of 12 inch duct and 4 12 inch dampers and 4 grilles to cover the ceiling openings in your home. It is interesting to note that other suppliers offer air flows that are close to this. QuietCool has 5170CFM for $1569. Ventcool has 5506 CFM but their price is $2,090. Airscape has 5527 CFM but their price is the highest at $2,289.
30 INCH 7600 CFM $2000
This fan frame had to be cut in two to fit it through the attic hatch. That process was easy and the result was nearly like new. This is a performance point (7600 CFM) that has been met by other means using 2 smaller fans in a home. An example is the IN3620 that pulls 3620 CFM and costs $1200. 2 of them will pull 7,240 CFM at a price of $2,400.. That has advantages in that you can use one for one area of your home and the other for another. But the initial cost is higher for the fans and installation.
36 INCH 9700 CFM $2200
This fan frame had to be cut in two to fit it through the attic hatch. That process was easy and the result was nearly like new. This is a performance point (9700 CFM) that can be met by other means using 2 smaller fans in a home. An example is the IN4740 that pulls 4750CFM at a price of $1400 That has advantages in that you can use one for one area of your home and the other for another. But the initial cost is higher for the fans and installation.
48 INCH 12,600 CFM $2600
This fan frame also had to be cut in two to fit it through the attic hatch. That process was easy and the result was just like new. This system comes with 3 20 inch duct connectors, 3 20 inch dampers, 3 grilles and 100 feet of 20 inch duct.
ROOFTOP MOUNTED WHFANS IN 3 SIZES, 1500 CFM, 3750 CFM AND 8005 CFM
Below are pictures of the 8005 CFM rooftop that was first built and sold in 2016. It uses the best rain hat in history, a vertical blade turbine created by Edmonds in Australia. They have sold thousands around the world for years. I obtained their permission to use it here and I now have a patent pending on its design. This is used on each of the 3 models.
A LOOK AT OTHER SOURCES UPDATED JULY 2023
In 2023 the number of sources has shrunk to just 4 HERE ARE THE 3 OTHER SOURCES
2023 has brought major changes to this market ComfortCool changed into a distributor for other brands. Tamarack is now selling Airscape fans QADeluxe and CentricAir seem to be closed – their phones do not work
So here are the remaining sources for fans like the fans I offer you:
Airscape has 2 series of attic mounted fans , “Sierra” and “Ventura”. And a 3rd fan style, the Direct Vent System (DVS), which is designed for homes with no attics. The Sierra line comes with more expensive motorized damper doors and the Ventura comes with economical gravity dampers. And those fans have 2 useful air flows. The prices are
- Sierra 3400 3.440 CFM $2,049
- Sierra 5300 5,527 $2,289
- Ventura 3200 3,132 $1,459
- Ventura 5300 5,497 $1,799
- The DVS offers 5,527 CFM at 932 watts for $2,819
This is the company that created the modern attic mounted whole house fan as we know it today. Dana Stevenson and his electrician partner invented the first ducted fan in 1999. Today they offer 4 families of fans, their Stealth, Trident, Energy Saver and Classic. I am showing only the Stealth and ES because the others use PSC motors (permanent split capacitor) that are far less efficient. As an example, their Trident 7.0 pulls 5300 CFM at 1147 watts while the Stealth 7.0 pulls 5200 CFM at 725 watts. I do not recommend PSC motors and I only supply EC motors.
WHY 4 FAMILIES? QC decided to make the Stealth and Trident families available only through their professional installers while the ES and Classic are available to anyone online who wants to do it yourself
So here are the prices for their Energy Saver fans are below. The Stealth prices are not public and only available through their installers.
- ES1500 1010 CFM $699
- ES2250 1850 809
- ES3100 2400 979
- ES5400 3810 1349
- ES6000 4040 1469
- ES7000 5170 1569
VC makes two series – one the Tahoe that is the cheaper PSC motor, the other the Summit that offers EC motors. Here are the EC fans. Warranty is 15 years on these.
So now to make this crystal clear, below you can see the oldest 3 sources but as you can see, Airscape has only one that competes and the price is high. And I have purposely priced mine below QuietCool even though I offer a better warranty (16 yrs vs 15 but that is not huge)
