Fans for Greenhouses
Super Fans are a family of brushless motor DC powered high efficiency ventilation fans that operate directly from solar panels giving you the cooling effect needed when the sun is at its hottest. Super fans can also operate from 24 volt batteries. Super Fan is made in the USA.
Super Fan is an ideal greenhouse fan and is also frequently used for agricultural and horticultural ventilation, attic cooling and exhaust applications.

Super Fan Use In Greenhouses
Ventilation requirements in greenhouses vary with the weather and time of the year. If you are using your greenhouse year round, ventilation needs can range from 100 percent air volume exchange per minute during the Summer to only 10 to 30 percent air volume exchange per minute from Fall to Spring. This information may be helpful: Greenhouse Ventilation Strategies with Solar Powered Fans.
A single fan cannot usually meet this range of air movement requirements. It takes at least two fans, preferably one pushing and one pulling. We have some other ideas about how you can expand the variability of you Super Fans if you are willing to use 12 volt solar panels wired in series to make 24 volts during the peak of the Summer, and change the connections over to 12 volts during the times of the year when slower fans speeds will meet your requirements.
Here are some basic rules of thumb calculations for greenhouse air volumes:
Your Super Fan selection should be based on the fan CFM capacity. Here's an example:
Super Fan Performance Factors
Super Fans have excellent performance and durability. These fans will provide you with many years of service with little maintenance thanks to their brushless motors, provided a few simple precautions are adhered to:
Constant use and abuse from nature will eventually wear some Super Fan parts and components. Replacement parts for every component are available. With simple tools and elementary mechanical skills you will be able to replace these parts with confidence.
Solar Power For Your Super Fan
Super Fans will operate on voltages from 15 up to 44. Super Fans will not operate directly from a 12 volt battery, but we have a solution so that you can run the fan from 12 volts. The life of the brushless motor is rated for 50,000 hours of continuous use.
With Super Fan you can purchase the fan only, or Sunshine Works can provide a special kit for the fan of your choice which includes the fan, a solar panel, wire, connectors, fuses, circuit breakers, line voltage thermostat switches, on off switches, lightning arrestors or whatever you need for your installation.
We can help you configure your Super Fan and solar components to meet the requirements of your applications including the option to use multiple fans from a single large solar panel.
