homefire Posted January 10, 2014 Share Posted January 10, 2014 ??? No Set figure that I know of. You want enough to make the dirt Boil like it would with a water sluice. Depends on size, Volume , Area and Dirt. Quote Link to comment Share on other sites More sharing options...
Bedrock Bob Posted January 10, 2014 Share Posted January 10, 2014 Cfm is not a relevant measurement. You need static pressure. Your fan needs to maintain about 3" static pressure and enough cfm to handle whatever size table you are running.Hint - A leaf blower is good for a small drywasher. I am not sure I know of a 12v analogy of a leaf blower. Quote Link to comment Share on other sites More sharing options...
devilishjim Posted January 10, 2014 Share Posted January 10, 2014 I believe my Echo is capable of 160CFM if that helps Quote Link to comment Share on other sites More sharing options...
