Off grid Greenhouse Inflation Fan Application

[ghurd]

The one I mentioned may be the 1st one on page 54.

Wow!  Fan.  12V, 20.5W, 2.53" H2O.  Page 41.

The first blower on page 66 is impressive, if it has no leaks.  12V, 170ma, 0.97" H20, 2W (Two Watts!).

Check this out. No electricity needed and it only works when you want it to--when the wind blows. (Let me know if you find instructions as to how to build this, because I want one....maybe you can figure it out just by looking at the photo.)

Since this thread has been useful to others (I have seen info in this thread used by other growers), I have an update.  Here is a way to reduce the power drain.

Normally, these fans run 24/7; however, with this setup, it will run only to provide the required pressure needed for inflation.

Did you try any of the DC muffin fans in your green house?
