The Scalper portion of the unit consists of a wire cylinder either 12″ or 18″ in diameter and will match the width of the Aspirator portion of the unit. Premier Scalper/Aspirators are used to scalp off or remove oversize material as well as an accurate winnowing or aspiration of the product to remove light material such as chaff and small seeds.
