QC Manufacturing continues to take bold steps towards improving our systems to make them stand apart from every other whole house ventilation system on the market.
We have redesigned our Classic Line damper system. The newly designed damper box at ceiling level re-places the “behind-the-motor” butterfly gravity damper that has served the Classic Line so well. The new damper boxes provide two new improvements/benefits:
1) The R-Value of all Classic fans has increased from R-4.2 to R-5.
2) The redesign reduces the length and weight of the fan motor cylinder thus making installation even easier.
The second Classic Line change is purely cosmetic. The new fan cylinders are now powder-coated a nice “American Blue”. And we did this because, well, not only did we want to be the best whole house fan in the world, but we wanted to be purdy, too!
