2017 mainstays 20 inch vs Patton 18 inch high velocity fan 

I wonder you could try those fans off that inverter and you can do a video on it which one pulls more the 18 inch fan or the 20 inch fan

Nice comparison video bro between new and old not bad considering it moves a lot of air

good comparison i enjoyed the video bro i like the Patton better get a 18 inch TPI so you can compare it up against the Patton hope to see the video soon
