Fan Speed Controllers

Fan speed controllers offer a practical solution for managing cooling performance and minimising noise generation in HVAC, industrial and IT applications. These versatile devices provide precise control over fan speeds, resulting in enhanced cooling efficiency, reduced noise levels, and prolonged fan lifespan. By incorporating a fan controller into your setup, you can optimise the energy consumption, performance, and reliability of your equipment.

RS offer a range of high-quality Single-Phase fan speed controllers from leading industry brands including Vent-Axia, ABB, ebm-papst and Dimplex. You can find out more in our fan speed controllers guide.

Fan Speed Controller Features & Applications

Fan speed controllers are essential in HVAC systems, to offer precise control over extractor fan, circulation fan, and ventilation unit airflow. By adjusting fan speed to match environmental demands, these devices help optimise energy use, reduce system noise, and extend equipment lifespan.

• Variable Speed Controllers – Offering adjustable fan speeds to allow operators to select the desired airflow or temperature levels
• Thermostatic Controllers - These controllers will increase or decrease fan speed based on real-time temperature readings
• Time-Based Controllers – These can be used to manage fan speed based on chosen presets, ideal for ventilation systems.
