All our fans hang from your rafters for quiet operation

Every ceiling opening gets a custom made designer round frame with a white grille.

All our systems use dampers right at the ceiling

This is the heart of the powerful squirrel cage blower systems. Note the door that opens only when the blower is on and closes to prevent attic air from flowing down.

 

We offer optional speed controls for all the fans but not the squirrel cages.

All our systems come with a reliable 13 amp remote AC control to reduce your wiring job.

Here is the INVISCO 4 room collector that allows you to connect any of the fans or blowers to 4 rooms.

HIGHEST CFMS
Invisco offers the highest CFM capacities ever offered in attic mounted ducted systems.

ONE SYSTEM FOR MULTIPLE ROOMS
Now you can connect one system to 2, 3, 4 or more rooms and close the room’s door and still cool each room.

R38 INSULATION FOR COLD CLIMATES
Invisco engineers have developed the first R38 insulated ceiling duct adapter. This adapter combines gravity operated “butterfly” dampers, NASA spinoff Aerogel, standard cellulose insulation, a “thermally broken” duct body and trapped air to give you the best insulation you can find. And the R rating can be as high as R60 when you add more insulation.

QUIETCOOL SYSTEMS CAN NOW GET R38
Invisco has 5 sizes of the R38 ceiling adapter including models to fit the standard 14 inch diameter and 16 inch diameter QuietCool whole house fan system ducts. The other sizes are 12 inch diameter, 18 and 20.

The table below shows some of our systems. We do not sell single room systems, only systems designed to be connected to 2 or more rooms. Note that not all systems are listed. For instance, it is possible to connect any one of the larger systems to 5 or more rooms. The tradoff is the speed of cooling.

All the systems with R in the number come complete with the thermally broken ducts and dampers (2 per room), NASA
spinoff aerogel insulation and accessories to make each room’s ceiling interface an R38 rated system or better. (The R rating goes up as you add more thickness to the cellulose insulation around the ceiling ducts and dampers). Invisco dampers use cellulose with R ratings up to R60.

The larger systems are so powerful that they cannot be installed for fewer than 2-4 rooms.

IN1600-2  is our  only squirrel cage system. Powerful and quiet. The Youtube video shows one pulling all the air out of a 10 by 12 foot room in one minute. This is also the only system offered that uses a reconditioned blower and motor. That is why it is less expensive than the IN1200-2

IN1600-4 is our 4 room squirrel cage system. This is supplied with lots of duct so you can connect 4 rooms that are 20-30 feet apart or more. Note that this means you can close the doors to each room and still pull air in the window, unlike central  hall mounted systems.

IN2540 is recommended for multiple rooms using ducts so you can hide it up in the attic to make it super quiet and STILL move a LOT of air.

IN3620 is also recommended for multiple rooms because it can be ducted to several rooms so each room can have the door closed and still cool it.

IN4750 is even better than the IN3620 and is perfect for ducting to many rooms.

IN6000 is our latest innovation. Invisco is the first company to offer the popular 30 inch ceiling fans in a custom made box for your attic. Imagine, 6000 CFM up high in the attic and super quiet. We include 2 (two)   18 inch ducts for maximum air flow. But you can add more ducts to more rooms for a low cost per room.

IN10500-4 is another new innovation. We put a 36 inch fan in a box in your attic for one of the most powerful whole house fans ever made. Our custom made box has 4 (four) 18 inch ducts to handle the 10,500 ubic feet per minute air flow. This will suck the ashes from your fireplace if you are not careful. Note that our engineers have designed a box that comes apart into sections that are easy to lift into newer home attics.

Last but not least, our IN14500-4 is the ultimate air mover. This 42 inch fan is a legend. Few homeowners have experienced the power this offers. Now you can put it up in your attic for super low noise. And move a TON of air. We ship this with 20 inch ducts – 4 of them – just barely able to handle the volumes of air. And our custom made box is crafted in sections so it can be lifted through almost any newer attic access.

We supply these systems with everything you need – steel straps to hang the machines from the rafters, all the duct you will need to connect to the ceilings, fittings for the ceiling to cover the duct, and a remote control AC switch so you don’t need to do any fancy wiring. AND we include our “butterfly” damper to prevent cold air from coming down the ducts. Last but not least you get our designer grade custom ROUND ceiling frame and grille.

AND we offer a variable speed control on all the fan products for infinite control over air flow and sound.
