Webb Wheel Products' Vortex drum is a high performance, cost efficient solution for meeting new federal stopping distance regulations that require shorter stopping distances. The drum is lighter than standard drums but is manufactured from the same, reliable grey iron material. It runs cooler because of its design with reduced wall thickness, a centerline squealer band and external ribs. The superior heat dissipation characteristics of the Vortex drums can maximize lining life and reduce life cycle costs.
