You have many decisions to make: Do you want

VENTS IN YOUR ATTIC – HOW MANY DO YOU NEED?

EFFICIENCY – WHAT DOES IT GET YOU?

INSULATION - IS IT SUPER COLD IN THE WINTER?

CALIFORNIA ENERGY COMMISSION LISTING – WHAT DOES IT MEAN?

SILVER FOIL ATTIC RADIANT BARRIER – HOW GOOD IS IT?

ACCESS TO YOUR ATTIC – YOU NEED TO KNOW HOW BIG IT IS

JOIST SPACING – DO YOU KNOW YOURS?

Rafter Mounted Systems

These are the quietest systems you can find. Not only are the fans quiet all by themselves, but when you hang them from your rafters high above your insulated ceilings and close the attic access hatch, you barely hear them and you don’t see them.

There are just a few manufacturers of these systems. Here are some highlights:

Airscape

In 2012 Airscape  introduced new web based remote controls for their  3500 and 4400 CFM machines. These controls are usable with laptops, desktops, tablets and smart phones. Airscape also added ECM motors to those  models to achieve better efficiency. But instead of taking advantage of the infinite speed control available from the ECM motors Airscape chose to provide 5 speeds on the 3500 and 6 speeds on the 4400.

Models are 1000, 1532, 1700, 2800, 3500  and 4400 CFM

Invisco

For 2013 Invisco is announcing the world’s first fully automatic temperature sensing “SmartSpeed(tm)” that knows how hot your home is. The system uses the high technology super  efficiency EC (electronically commutated ) motors to start up on high speed when the inside is 85 degrees or more. Then as the temperature in your home drops under 85 the SmartSpeed automatically lowers the speed and the power consumption drops automatically until, at 60 to 75 degrees (depending on your setting), the fan turns off automatically.

Invisco offers X10 and Insteon PC and smart phone  remote control for all systems.

Invisco is the only company to offer CFM levels higher than 4700 from one motor and fan blade. The larger systems pull so much air volume that they must be connected to more than one ceiling opening. The 8400 must have 2 18 inch ducts at a minimum and the larger units are shipped with 3 or 4 18 inch or 20 inch ducts at a minimum. CFM performance range is 3620 up to over 15,000.

Models are 3620, 3620R, 4750,  4750R, 5600, 5600R, 8400, 8400R, 10,600, 10600R, 14,500, 14500R, and  15,000 CFM

The R in the part number indicates that the systems are shipped with the Patent Pending R60  insulated dampers.

QuietCool

For 2013 QuietCool has announced new higher CFM systems – the QC4700, ES-5400 and QC6400. Of these, the larger systems use 2 fans and motors. The 4700 is one motor and blade. The ES is their “EnergySaver” line that uses the new ECM brushless DC motors similar to those used by Invisco. The difference is that Invisco takes advantage of the infinite speed capability of ECM but QC does not.

QuietCool has also started selling “ByeBye” remote controls. Made in the UK, they are becoming popular and can be found on Amazon now. QC sells the starter kit for $48.95 and Amazon has it for $19.95.

QuietCool has announced a new guarantee plan – they divided their systems into two groups – the Authorized Dealer Fans – those are their Stealth and Trident Lines. This group of fans includes two speed fans, the most energy efficient fans and a 15 year warranty. The second group is their Consumer Fans, which include their original Classic Fan Line and the Energy Saver Line, both backed by a 10 year warranty. QuietCool is the only supplier of 2 speed fans to label them “variable speed”. If you truly want infinitely variable speed  only one supplier has them.

Models are 1000, 1250, 1500, 1545, 1700, 2000, 2250, 2310, 2560, 2850, 2970, 3045 and 3310 CFM

Note that QC offers higher CFM but those systems use multiple fans.

Tamarack Technologies

Tamarack systems are almost all  ceiling mounted, not ducted. The exception is their  1100 and 2200 CFM “Infinity” models.

Models are HV1100, HV 2200, HV1600, HV3400 and HV1450.

I need to mention R.E. Williams (1850 CFM with (4) 8 inch inputs from 4 ducts) These 8 inch ducts are not competitive with the systems shown above.
