Disposal Controller Base Unit With Switch, Chrome

Moen ARC-4200 Garbage Disposal Air Switch Controller – 120V, Controller Base Only

The Moen ARC-4200 is a disposal air switch controller base designed for safe, code-compliant operation of continuous-feed garbage disposals. This unit is intended for installations where a wall switch is not practical, such as kitchen islands or peninsula layouts. The controller operates using air pressure generated by a separately sold air switch button, providing an alternative to hard-wired electrical switching.

The controller connects to a standard 120V outlet and supports all Moen continuous-feed disposal models. It mounts beneath the sink and is activated by air pressure through a pneumatic line routed to the sink deck or countertop-mounted switch.
