Product Overview

  • Helps to cool and ventilate rooms for energy savings
  • Designed for quiet operation
  • Fast and easy installation
The QuietCool brand of whole house fans has taken America by storm. The QC CL-4700 advanced whole house fan is a new take on the idea of whole house ventilation. Whole house ventilation allows you to bring the cooler outdoor air through your windows, home and attic space to thoroughly cool and ventilate both the home and attic. The process of thoroughly cooling the home and attic is called thermal mass cooling. This is what allows your home to stay cooler the next day and resist heating up as much as it would if you only ran the AC to cool the home. QuietCool uses a unique, patented design that uses an acoustical duct attached to an R5 damper box. The result is almost zero noise vibration and whisper quiet operation. The QuietCool QC CL-4700 is designed to be installed centrally in midsize homes. Simply open a window when you get home from work, flip on the QuietCool and enjoy a peaceful and cool evening relaxing. And for an even better system, purchase another smaller QuietCool unit for your master bedroom to enjoy a full range of cooling and ventilation. Better yet, QuietCool is proudly designed with a 98% customer satisfaction.
  • QuietCool advanced whole house fans use and improve upon the principle of ventilation cooling with savings of up to 50-90% off traditional cooling methods such as A/C
  • 5.89 sq. ft. of net free attic venting required for proper ventilation
  • Cools and ventilates homes up to 2210 sq. ft. for optimum performance
  • Fan motor head hangs from the rafters in the attic with a small ceiling cut-out for the air intake grille (14 in. x 30 in. ceiling cut-out)
  • Moves air at a rate of 4415 CFM on high and 3402 CFM on low
  • 551-Watt PSC motor on high and 415-Watts on low ensures efficient operation and airflow
  • QuietCool 8-hour countdown timer and 2-speed control switch sold separately
  • Installation is simple with a typical 1 to 2-hour install time with no framing or joist-cutting required (fits 16 or 24 on-center)
  • R5 damper box at the ceiling level helps insulate the home from the attic during the cold times of the year when the fan is off
  • HVI-916 airflow rate for California: 3230 CFM

Is the intake grill in the ceiling easy to clean? Does it have to be covered in the winter to prevent heat loss to the attic?
Asked by: Birdie
We dust ours with a swiffer a few times per season and we do not cover ours in the winter. I believe the approx. 1" thick dampers/doors are insulated and that seems sufficient.

Do any of your units come with a wireless remote control? I would rather have that versus a wall mounted control unit.
Asked by: BigNEO
I don't know if they come with a wireless remote control, however, you can add a smart module. https://quietcoolsystems.com/products/wi-fi-smart-control/

What size of house works best with this unit

Asked by: Zappa1
My home is ~2000sf and I am disappointed with the performance of this unit, even though it is supposed to be big enough for this square footage

Can this be vented directly outside through a gable vent?

Our farm house attic is too small to have proper venting for the size of fan we need (large addition downstairs). Is it possible to install this in the attic but just vent it directly out the gable end vents?
Asked by: Mike
I suppose it could. I have it in the middle of the attic and it escapes through all the vents. The hose is about 10 feet long so it really depends on where you mount it in the house.

Fan was great and quite, only hiccup was installing it in a 102 year old house. Ceiling had multiple layers of ceiling so could not install baffle the way it was meant, had to install from room side up, but my handyman did an excellent job modify it.

Keeping out cooling bills to a minimum. We live in a dry climate that gets to 95 degrees during the day in July. We only have to turn the central air on a few hours in the late afternoon. Normally without the house fan, we would run the Air most of the day. Once the outside temp falls into the mid 70s at dusk or after dark, we open the windows part way in several locations in the house and turn on the house fan for 4-5 hours into the night. The fan pulls cool air through the house and into the attic. The house is nice and cool in the morning into the mid 60's. We shut the windows and start the process over again. I come home at 5pm and the indoor temp is still around 72-73. Some times a bit warmer if the temps get to 100. The fan clears the heat in the attic at night and keeps a cool breeze going through the house at night. We sleep so goood.

Pulled very little amperage and did not overload the circuit at all. That was a concern. I think that the attic that it was installed into could use more gable vents, but they do not want to pay for that. That is the bottle neck in this scenario.
