Rapid Granulator's RG series has been a staple in the slow speed granulation category for many years with its screenless operation for brittle materials. Other small beside-the-press models include Rapid 150 & 200. The Rapid 300 & 400 Series are medium granulators that can be central or beside-the-press granulators. They also manufacture large granulators under the Rapid 500 & 600 Series name. Previous models such as the 2442 and the 1831 are popular on the used market. Most recently, Rapid has decided to control it's own production of equipment in Leetsdale, PA. Previously, The Conair Group was building Rapid equipment in its Franklin, PA plant.
