The QUIETCOOL QC-1500 (U.S. Patent Pending) 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 accoustical 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-1500 performs better than one
Type II whole house fan in all respects, but we recommend that one
QC-1500 be installed for each 500 Sq. ft. of living space (ideally one per
bedroom) 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.
