Weg has launched a new cost-effective, reliable and easy-to-use series of compact variable speed drives (VSDs) to enhance energy efficiency across a wide range of applications requiring low motor power. Designed to drive motors with power from 180W to 4kW, the CFW300 series is ideal for relatively small machinery such as centrifugal and metering pumps, fans and ventilators, stirrers and mixers, extruders, roller conveyors, cutting machines and rotary filters.
