Danfoss 131B8911 VLT AQUA Drive FC-202, a 3.0 kW / 4.0 HP three phase 380-480 V AC variable frequency drive with IP20 chassis enclosure and RFI Class A2 / C3 filter for water, wastewater, pump and HVAC motor control applications.
£669.00
The Danfoss 131B8911 is a compact and efficient AC variable frequency drive (VFD) designed for reliable motor control in water, wastewater, HVAC and industrial pump applications. As part of the Danfoss VLT AQUA Drive FC-202 series, it is engineered specifically for fluid handling systems where energy efficiency, smooth operation and dependable performance are essential.
This drive provides advanced pump-focused functionality in a compact IP20 chassis format. The VLT AQUA Drive range is widely used in water and wastewater systems because it helps optimise flow control, reduce energy consumption and minimise mechanical stress on pumps, motors and pipework.
With a rated output power of 3.0 kW / 4.0 HP and a three-phase 380–480 V AC supply, the 131B8911 is suitable for pump, fan and fluid control applications. Its built-in RFI Class A2 filter supports electromagnetic compatibility in suitable installations, while the IP20 chassis design allows straightforward installation inside electrical control panels.
Variable frequency drives such as the Danfoss VLT AQUA Drive FC-202 regulate motor speed by adjusting output voltage and frequency. In pump and fan systems, this allows flow and pressure to be controlled more accurately while reducing energy use compared with fixed-speed motor operation.
The 131B8911 is designed for compact control panel installations in water treatment, building services and industrial process systems. Its AQUA-focused functionality makes it suitable for pump control applications where smooth operation, reliable performance and reduced system stress are important.
