Details

The F20 Plus is our newest offering for heavy duty greenhouse and attic ventilation applications.

A 20 inch diameter blade set offers greater surface area to move a higher volume of air than seen with the 16 inch model.  The robust, brushless motor is well-suited for solar-direct applicaitons, where the simple combination of fan and solar panel are all that is needed to start moving some air!

Backwoods is now manufacturing, here in the USA, this brushless 20 inch, 12/24 volt ventilation fan. Our fan is designed to meet your needs every season in the greenhouse or attic install. Intended for use with 12 volt or 24 volt solar panels as low as 30 watts up to 250 watts and can be used in conjunction with 24 volt battery banks. It will also perform with 300 watt and 72 cell modules with open circuit voltages of 44 volts. The F20-PLUS is protected from moderate over-voltage and thermal fluctuations.

The Super Fan has been tested through a variety of panel and voltage configurations. We recommend three configurations for “small”, “medium”, and “large” applications. “Small”: all 12 volt panels; a 30 watt panel will provide an airflow of about 9 mph (estimated 1600 cuft/min). “Medium”: a 60 watt panel will produce up to 13 mph (estimated 2300 cuft/min). “Large”: a 135 watt panel will hit 17+ mph (estimated 3000 cuft/min) and faster.

The best thing about our new DC Super Fan 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 F20-PLUS will outperform other fans. Solve your circulation issue with this solar direct solution!  Be aware, the motor has a built-in 5 minute start delay to prevent stress on the motor during extremely low light conditions.  If disconnected and re-connected to power, there will be a delay before the blades start spinning again.

The F20-PLUS is not intended for use with 12 volt battery banks or AC power of any kind.
