The ultimate in case cleaning convenience, Lyman's Auto-Flo Enhanced Tumblers automatically separate clean cases from media using the unit's normal vibrating motion. When cases are clean, the user simply pulls the drain plug and the media drains from the exit port into the media drain pan (included). The 2200 features a high strength "Ultra-Thick" Roto Molded bowl which will last as long as you own your tumbler. The 1.5 gallon capacity is ideal for the large volume user and can clean 750 38 Special cases in one cycle. The 2200 also features a clear see-thru lid for inspecting cases during cleaning. A media drain pan is also included.
