The amazing thing about this fan is that it produces the same level of air flow at maximum speed, approximately 120 + cubic feet per minute, as the typical squirrel cage blower while only consuming 8 watts of power. The typical blower consumes 100+ watts of power and generates a much higher noise level.
The QFF-3804-V fan system contains four high technology brushless DC axial flow fans with an adjustable speed control. The fan speed can be set from the maximum design specification for the fans down to about 60% of maximum speed to reduce flow and sound level when required.. The 12 VDC adapter plugs into the power jack on the rear support leg.
The speed is adjusted by turning the black knurled shaft mounted on the leg of each fan.
Use the large quiet DC fireplace fan in large gas fireplaces greater than 40″ wide in great rooms, with high ceilings greater than 10′. The direct vent gas fireplace must have a 15″ wide air gap going up behind the firebox for the fan to be fully utilized.
Includes AC adapter.
