The GRAF Klaro E Professional 50PE is a high-performance sewage treatment system designed for domestic and commercial properties accommodating up to 50 people. Built around advanced SBR (Sequential Batch Reactor) lifting technology, this system ensures efficient, eco-friendly wastewater treatment with minimal maintenance and outstanding discharge quality.

This robust system features four injection-moulded underground tanks (each 6,500L), engineered for long-term durability and groundwater stability. The Klaro E Professional operates without any moving parts inside the tank, using three air lift pumps powered by a low-maintenance compressor housed in an internal control cabinet. The system is quiet, energy-efficient, and includes a holiday mode for reduced usage periods.

What makes the OneAdvanced unique?

- No live electrical parts in the water.
- Low Power Consumption.
- State-of-the-art tank manufacturing for maximum stability.
- Integrated self-cleaning sampling container.
- High Quality Components = Low Maintenance Costs.
