Tamarack HV3400 Ghost R-38 Whole House Fan

For larger homes, you need a Tamarack Ghost Whole House Fan. When the Ghost is turned on, the insulated doors of the upper part of the unit open. The fan then turns on, and pulls warm house air up through the grill supplied with the fan and installed in the ceiling of the floor below the unit  the fan pulls this air in, and forces the heated air out into your attic.  The pressure pushes the air out through the attic gable and roof vents. Because the motor is housed in the top part of the unit, this model is significantly quieter than your typical whole house fan. The Ghost two speed fan is rated at 3400 CFM (cubic feet per minute) on high, 1900 CFM on low. It comes with a 6′ power cord for easy installation, a remote control, and a white interior grill. This is an excellent choice for California residents seeking to meet the 2 CFM/square foot ventilation code requirement for a 1500 square foot home.Specifications115 VACInsulated R-38 doors that open only when the fan is on, so there is no hole in your attic insulation.48 lbscomes in two pieces – total height 27 5/8″, rough opening 26″ x 29 1/2″Requires 9 square feet of attic ventCan be hardwired to a wall switch   The price includes an attractive white metal grill   Click on Product Video below to view installation and operation of the Ghost whole house fan
