Optional matching sensors monitor the ambient conditions and provide real time feedback to the fan. The fan's on-board microprocessor adjusts the speed and therefore modulates the ventilation rate to match the specific requirements of the area. The Vortair® EC fans are a simple "plug and play" system which means installers do not need to have specialised control programming knowledge.

Vortair EC Series feature a heavy duty galvanised steel circular fan casing that can be retrofitted into axial fan installations that may require greater static pressure. They are available in 5 case sizes ranging from 450 to 710mm diameter (280 to 450mm impeller diameters).

• Innovative mixed-flow impellers produce powerful airflows without generating high noise levels.
• EC motor features reverse polarity protection, locked rotor protection and soft starting.
• No additional electrical protection such as contactors are required.
• All models supplied standard with 0-10V control input. Diameter sizes from 400mm and above can be pre-configured to suit specific sensors and specific applications.
• A full range of sensors are available including differential pressure, humidity, temperature, air velocity and pollutant.
• Can be run as an independent ventilation source or integrated into most building management systems.
• Heavy duty galvanised steel construction.
• Can be retrofitted into standard 450 to 710mm axial fan installations.
• Mixed-Flow impellers suit applications where medium to high air pressure is required.
• Can be mounted in any position.
