Flottweg Separation Technology has announced the launch of its newest innovation – the FW400 Decanter – a next-generation decanter centrifuge engineered to deliver exceptional separation performance, increased process flexibility and simplified operation for a broad range of industrial applications.
Designed around the evolving needs of modern processing facilities, the FW400 represents a significant advancement in mechanical separation technology. Built on decades of engineering expertise and proven field experience, the new decanter helps processors achieve higher throughput, improved product quality and lower operating costs while providing the adaptability needed for changing production requirements.
“Industrial processors today face increasing pressure to improve efficiency while controlling operating costs and maintaining consistent product quality,” said Daniel Lakovic, business development manager for Flottweg Separation Technology. “The FW400 was developed specifically to address those challenges by combining higher separation performance with a flexible platform that can evolve alongside our customers’ operations.”
Unlike conventional decanter centrifuges, the FW400 was engineered around three core design principles: Performance Boost, Flex Concept and Human-Centered Design.
Greater performance where it matters most
The FW400 delivers higher throughput and enhanced solid-liquid separation through increased bowl speed, optimized geometry and greater torque capabilities. A super-deep pond design improves clarification while reducing overall energy consumption, allowing operators to maximize production without sacrificing efficiency.
Its flow-optimized, adjustable impeller enables precise process control, helping facilities optimize separation performance across varying operating conditions while maintaining consistent product quality.

Flexible by design
Recognizing that no two separation processes are exactly alike, Flottweg designed the FW400 with a modular architecture that can be configured for a wide variety of applications. The Flex Concept allows operators to customize the machine to meet specific process requirements today while providing the ability to add new features and capabilities as production needs evolve. Rather than replacing equipment to meet future demands, customers can upgrade the FW400 platform, protecting their investment over the long term.
The decanter is ideally suited for numerous industries, including:
- Municipal wastewater treatment
- Industrial wastewater processing
- Pharmaceutical manufacturing
- Juice production
- Minerals and mining
- Industrial processing applications
Engineered around the operator
Beyond performance, Flottweg focused on making the FW400 easier to operate and maintain. The new machine incorporates a range of operator-focused improvements, including an enhanced housing seal to reduce environmental contamination, a foldable belt guard that simplifies maintenance access and a low-noise design that improves workplace conditions. These features reduce downtime, streamline routine service and help maintenance personnel work more efficiently.
The FW400’s optimized hygiene concept also improves cleaning effectiveness through redesigned rinse positions and enhanced cleaning geometry that minimizes product buildup and shortens cleaning cycles.
Sustainable performance with lower operating costs
Efficiency extends beyond throughput. The FW400 is designed to reduce energy consumption while improving overall process economics. When equipped with Flottweg’s proven Recuvane® energy recovery system, the decanter can reclaim rotational energy that would otherwise be lost during liquid discharge, reducing energy consumption by approximately 10 to 20 per cent depending on the application.
The combination of higher separation efficiency, lower energy requirements and reduced maintenance helps processors decrease total operating costs while supporting more sustainable manufacturing practices.
Built for today’s processes – and for the future
Whether recovering valuable product, clarifying liquids or dewatering solids, the FW400 delivers the flexibility, reliability and performance today’s processors require. With its modular design, enhanced process control and operator-focused engineering, the new FW400 reflects Flottweg’s continued commitment to developing innovative separation solutions that help customers improve productivity, maximize uptime and prepare for future operational demands.
