Ruck MTP 40-20X Fan Speed Controller for Ruck AC Ventilation Fans

The Ruck MTP 40-20X fan speed controller gives precise variable control of Ruck AC ventilation fans, letting growers set exhaust airflow to a room's load instead of running wide open. Built for commercial and industrial spaces, this variable fan speed controller installs easily and helps steady airflow while trimming energy use and fan wear. Ruck MTP 40-20X Fan Speed Controller for Precise Airflow The Ruck MTP 40-20X fan speed controller varies the speed of Ruck AC ventilation fans so you can match exhaust airflow to a grow room's actual heat and humidity load rather than running the fan flat out. Wired inline between the fan and its power, it lets you dial airflow up during peak light hours and back down for quieter dark-cycle running. The durable housing is built for the demanding, high-humidity conditions of grow rooms, greenhouses, and commercial ventilation. Variable Fan Speed Controller for Commercial Ventilation As a variable fan speed controller, the MTP 40-20X suits larger commercial and industrial setups where holding a target airflow matters for both climate stability and equipment life — running a fan at a controlled speed reduces wear versus constant full-throttle operation. Growers typically set it once for a room's baseline exhaust, then adjust seasonally as outdoor temperatures shift. It's designed to integrate cleanly with Ruck ventilation systems for reliable day-in, day-out control. Key Features Variable speed control: Adjusts Ruck AC ventilation fans smoothly to the airflow a room actually needs. Matches airflow to load: Dial exhaust up during peak light hours and down for quieter dark-cycle running. Durable build: Housing made for the high-humidity conditions of grow rooms and greenhouses. Simple inline installation: Wires between the fan and its power for simple setup. Commercial and industrial ready: Suited to larger Ruck ventilation systems where steady airflow matters.
