The Quiet Giant Whole House Fan QC-4500 The Quiet Giant whole house fan is a powerful 4500 CFM, 2 speed whole house fan.
This revolutionary new product is the perfect addition to the current line of QC-2250 whole house fans.
The Quiet Giant can be used to create a powerful, yet amazingly quiet flow of air in your home.
Used alone or in combination with the other quiet cool fans, these amazing fans will give you unprecedented flexibility in designing the perfect whole house cooling solution to meet your specific needs.
The Quiet Giant is mounted in the attic and connects to an attractive ceiling grill with 2 patented acoustical insulated ducts. This unique design helps to eliminates all vibration, rattle, and noise, common to all other whole house fans.
The Quiet Giant consist of basically two of our QC-2250 B units, but with larger, higher speed motors. The two fans each come with 6 foot long ducting that connected to one ceiling box and one ceiling grill for simple installation. The ceiling box is 14 1/4"x 36 1/4.
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.
The Quiet Giant is ideal for customers who want a single fan installed in a central hallway or it can be used in a multi-fan configuration, by installing the Quiet Giant in the central hallway and installing our smaller cfm QC fans in the bedrooms for maximum air flow and flexibility.
When you compare the price per CFM and the amazingly low noise levels of the Quiet Cool fans, you will find that our fans are in a class of their own. ORDER YOURS TODAY!
