Becks drywasher

[Lefty2u]

I am curious about the Beck's drywasher . I saw one and noticed that it did not
have a cloth bellows . It appears to have a air box in which the bottom goes up
and down and forces air through the riffles. Does anyone know about this concept?
Also if it is better than using a cloth bellows?

Dry Washer with Blower, i use vaccum pack i made using a leaf blower ( about $80 or $90 ) so i am able to vacum the cracks, doubles for the K140 Dry washer the less you have to hual the beeter

Well I read about that concept somewhere. It basically an air champer of some sort that instead of a cloth bellow it uses just the underside of the riffles box. Don't know if it is better than the cloth thing.

Anyway I prefer much a puffer type DW than the blowers ones, it just quieter and catches most of the fine gold particles.

What ya want quiet or gold?? Blower outperforms ,out recovers and processes many times more materials with much better fines recovery. You want inside the box ,a offset adjustable throw on the fan blade to oscilate and create a panning style action and good to go-John
