4-Stage Filtration Process

Stage 1 – Sediment Filtration

Removes dirt, rust, sand, and larger particles.

Stage 2 – Carbon Filtration

Removes chlorine, VOCs, and contaminants that can damage RO membranes.

Stage 3 – Reverse Osmosis Filtration

High-efficiency low-pressure RO membranes remove dissolved solids and impurities.

Stage 4 – DI Resin Polishing

Final DI stage removes remaining TDS for spotless pure water cleaning.

Water Pressure Requirements

• Recommended pressure: 60–90 PSI
• Low water pressure below 50 PSI may reduce performance
• Booster pump recommended where mains pressure is low

The integrated control system can automatically operate a compatible booster pump during production cycles.

Ideal For

• Commercial window cleaning companies
• Multi-vehicle fleet operations
• High-volume pure water production
• Workshop and depot installations
• Businesses requiring automated water systems

Low Maintenance & Efficient Operation

The automated membrane flushing system helps:

• Extend membrane lifespan
• Improve filtration efficiency
• Reduce manual maintenance
• Lower long-term operating costs

The intelligent refill system automatically maintains water levels, ensuring your pure water supply is always ready when needed.
