Battery Based DC Super Fan - 24 inch - 12/24V

The F24-B greenhouse/attic fan is the 24" Battery-Based model of the DC Super Fan product line featured at Backwoods.

The battery based models of the Super Fans use a different motor than the solar direct fans; more appropriate  to run at the voltage levels seen on battery banks. Battery based solutions allow the fan to operate at nighttime or in overcast weather.

The F24-B has been tested over a range of voltage levels to evaluate power consumption and air movement.

Voltage: 12.0 12.5 13.0 13.5 25.0 26.0 27.0
Watts: 34.8 39.3  44  49 89 91.52  90
CFM: 2217 2270 2772 3537 3127 3696 3775

As shown by the numbers, small variations at the 12 volt levels create a modest range of air flow volumes.  At the higher 24 volt levels though, the motor is near maxxed out, with little variation in power consumption and air speed.  For applications that don't need the full CFM volumes a speed control (A-FAN-CONTROL, sold separately) can be used to limit the CFM. 

The F24-B motor has been successfully tested at voltages as low 11.5 volts, but may cease to operate at 11.2 volts or lower.

The best thing about the DC Super Fans is the brushless motor. Motor brush replacements were common on previous fans especially if they were run at high RPM’s. With no brushes the Super Fans will outperform other fans.

The F24-B is not intended for solar direct application or AC power of any kind.

2 Year Warranty from purchase date. All parts are replaceable and can be ordered individually as needed.
