The PowerLine® EC Series of In-Line centrifugal fans incorporate the latest state-of-the-art, energy saving EC motor technology and are most efficient where conditions vary during the course of the day. They feature fully integrated, infinitely variable speed control which eliminates the need for external VSDs, current overloads and motor phase protection.
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 PowerLine® EC fans are a simple "plug and play" system which means installers do not need to have specialised control programming knowledge.
They feature easy to fit 35mm TDF profile flange connections,
a robust yet lightweight galvanised steel construction and are available in 7 sizes ranging from 315 to 630mm diameter.
