Ruck MTP 21 Fan Speed Controller | 0-10V Potentiometer for EC Fans (10kΩ)

The Ruck MTP 21 fan speed controller gives precise, stepless control of Ruck EC inline fans through a 10 kΩ potentiometer dial and 0-10V signal. This 0-10V EC fan controller ships with cord and plug, carries an IP44 rating for dust and moisture, and mounts surface or flush.

Ruck MTP 21 Fan Speed Controller for Stepless EC Control

The Ruck MTP 21 fan speed controller is a 10 kΩ potentiometer that steplessly varies the speed of Ruck EC inline fans over a 0-10V signal, so you can dial airflow anywhere in the range instead of jumping between fixed steps. It pairs directly with Ruck's Prime EVO EC and S-Prime EVO EC fans and any other 0-10V-controllable EC motor. A switching contact rated 1A at 250V AC and 2.5A at 12V DC handles typical ventilation wiring.

Durable 0-10V EC Fan Controller That Mounts Anywhere

Built for real installs, this 0-10V EC fan controller carries an IP44 rating against dust and moisture and holds up in ambient temperatures to 50°C (122°F), so it survives a humid grow room or greenhouse wall. Growers usually mount it at eye level near the room entry to trim exhaust airflow to the canopy load — surface-mount on a panel or flush into a wall box, whichever the layout calls for. It arrives with cord and plug for a quick connection to a compatible EC fan.
