WHY CONVOLUTED WAFERS ARE MORE ECONOMICAL THAN FLAT WAFERS Wafers are used to make main brooms for mechanical sweepers, road construction sweepers, and sweeper attachments. Wafers are individual broom discs that stack on top of each other on a wafer rack to make a full broom core. There are two style wafers – Convoluted and Flat. Convoluted wafers have a wavy shape and flat wafers are well, flat. Most people tend to stick with whatever broom type or configuration is on the sweeper when the sweeper is purchased. If you’re using flat wafers you may want to see why switching to convoluted can save you time and money.
ECONOMICS OF CONVOLUTED VS. FLAT WAFERS
Compared to their larger cousin, the tube broom, wafers are compact, easy to store, and economical. The downside is that a broom core made of wafers typically gets changed in the shop, not in the field. Flat wafers require spacers to be placed in between each wafer when building a broom. A spacer is essentially the center ring of the wafer
