Equipment
has been making these dry washers for 8years now with over 500 satisfied customers. The advantage of it is the LEXAN riffle board. When high velocity air passes through the holes in the LEXAN board it creates an electrostatic property which attracts and hold the finest of GOLD flake. Also the counter weight fan assembly shakes the recovery box and forces the heavy finds into into the riffle corners.

LARGE SIZE UNIT
measures 17" x 26" hopper, 10" x 24" recovery box, stands 44" and weighs 24 lbs.
To operate requires a 3" x 10' RV black water waste hose attached to a leaf blower and to the bottom of the recovery box. When air from the blower passes through the LEXAN riffle board holes it blows off the lighter materials and leaves the heavy finds. Any blower that supplies 165 MPH/ 350 CFM works fine.
