The F16-B greenhouse/attic fan is the 16" 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 F16-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 Watts: 18.0 20.0 22.1 24.3 122 130 CFM: 1064 1162 1272 1321 2091 2324
As shown by the numbers, small variations at the 12 volt levels create a modest range of air flow volumes. 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 F16-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 F16-B is not intended for solar direct application or AC power of any kind.
