The Quiet Cool QC 4500 (U S Patent) is called the Quiet Giant. It, like it's smaller brother the
QC 1500.

  • It is an innovative whole house fan that delivers superior
performance with 4,500 cubic feet per minute of airflow while
operating almost silently. It is mounted up in the attic and
connected to an attractive ceiling grill with two patented
acoustical insulated flexible ducts. This design eliminates all
vibration, rattle, and noise so common to all other whole
house fans. It is so quiet in operation that when installed in
a bedroom, persons are able to sleep without being able to
hear them.

  • It can be installed almost anywhere in the ceiling as long as
there is an attic above. It fits between 16" on center framing,
requires no carpentry work to install, and takes less than half
the time to install as a conventional whole house fan. It
comes with two separate motors and ducts, allowing for
two-speed operation by running only one motor or both
motors. Each motor has insulated, positive closing damper
doors that prevent the intrusion of attic air back into the
house when they are not in operation.
