4538 CFM Quiet Cool Whole House Exhaust Fan
This Quiet Cool 4500 Series fan is an innovative whole house fan that has none of the disadvantages of Type I and Type II fans. It's big advantage is that it is not mounted to the ceiling but instead is suspended in the attic with straps from the roof rafters. It's connected to an attractive ceiling grill with a patented acoustical insulated flexible duct, thus eliminating all vibration, rattle and noise in the house. It is so quiet in operation that it can be installed in a bedroom or sleeping room without a sleeping person being able to hear it.
This cleverly engineered system can be installed almost anywhere in a ceiling or vertical wall in less than 1/3 the time it takes to install a Type I or Type II whole house fan. It has a damper with insulated doors that prevents cold air intrusion in the wintertime. One QC-4500 performs better than one Type II whole house fan in all respects, but QC recommends that one QC-4500 be installed for each 1500 Sq. ft. of living space to obtain the cooling breeze of a Type I whole house fan. This also allows the cooling and ventilation to take affect even with the bedroom door closed as long as a window is open.
Quiet Cool fan systems are the best choice for homeowners based on energy savings, high quality, value, ability to move a large volume of air, ease of installation, aesthetic appearance, versatility, and above all, quiet operation.
