Fans for Greenhouses
Snap Fan is a family of 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. Snap Fan is made in the USA.
Snap Fan is an ideal greenhouse fan and is also frequently used for other agricultural and horticultural ventilation, cooling and exhaust requirements.

Snap 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 (opens in a new window).
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 Snap 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 Snap Fan selection should be based on the fan CFM capacity at .1 inches H2O. Here's an example:
