20″ 24V Battery Fan w/Frame *Special*
The F20-B greenhouse/attic fan is the 20″ Battery-Based model of the DC Super Fan product line featured at Backwoods.
The battery based models of the Super Fans use a brushless motor that is different from solar direct fan motors; 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 F20-B has been tested over a range of voltage levels to evaluate power consumption and air movement.
- 20″ fan moves 2,200 cfm of air
- Maximum power draw is about 50 watts
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 F20-B is not intended for solar direct application or AC power of any kind.
