Product descritipion

The Revolution 360 range utilises the latest three-core technology, ensuring best in class efficiency levels as well as whisper quiet operation. This range of EC motorised impellers and fans is optimised to provide aerodynamic efficiency and low acoustic noise at the higher static pressures encountered in today’s ventilation applications. Revolution 360 also provides customers significant intelligence and flexibility with the options of offering programmable constant volume, constant pressure or constant speed performance. Revolution 360 blends optimised performance system components and provides a motorised impeller with best in class performance for residential system applications.

Available in Torin-Sifan’s standard fan sizes, starting at 133 mm for backward-curved and 120 mm for forward-curved, the Revolution 360 range can also be adapted to offer customised solutions. Options available can vary from plug type and mounting hole position to fully bespoke designs for specific applications.

The backward-curved impeller range is available in two designs, one optimises performance in applications with higher pressures, the other excels where high airflows are required.
