Commodore food waste disposers contain Bio Shield, the anti-microbial agent incorporated in every engineered plastic component of the disposer that comes in contact with food waste. This anti-microbial property helps prevent bacteria from growing in the grinding chamber and therefore reduces bad odors. Commodore also utilizes the TorqueMaster balanced grinding system whose balanced armature, turntable, and impellers helps deliver a smooth, quiet disposer operation. TorqueMaster provides the maximum torque necessary to grind your food waste quickly and efficiently.
