High velocity air passes through the concentrator creating an electrostatic charge to attract gold and other metalliferous values. The hot air from the engine is ducted into the radial blower, preheating the air and concentrator to 50 degrees above ambient making it possibble to process a higher capacity of material and increases the electrostatic charge. An adjustable oscillation system creates increased vibration and air flow at lower engine speeds which increases fine gold production, especially in damp ground conditions. Equipped with an extra large hopper for greater capacity while steeper sides prevent material build up. The folding frame makes this model a dream for quick and easy set up.
