Core 4-Stage Filtration Process
⚙️ PP Sediment Filtration
A high-capacity polypropylene sediment filter removes suspended solids, rust, silt, sand, and large particulates from the feed water, protecting downstream components and extending the life of subsequent filters.
⚙️ UDF Activated Carbon Filtration
Granular activated carbon (UDF) effectively adsorbs chlorine, organic compounds, unpleasant tastes, odors, and residual color, improving water aesthetics and protecting the RO membrane from chlorine oxidation and damage.
⚙️ Reverse Osmosis (RO) Membrane
The core purification stage, utilizing a high-efficiency RO membrane to remove up to 99% of dissolved salts, heavy metals (lead, arsenic, mercury), bacteria, viruses, fluoride, nitrates, and other contaminants, producing pure, safe drinking water.
⚙️ T33 Post-Carbon Polishing
A premium coconut-shell activated carbon post-filter (T33) polishes the purified water after RO storage, removing any residual tastes or odors from the storage tank and delivering fresh, crisp, great-tasting water directly to the faucet or dispenser.

Key Features
4-Stage All-in-One Design
Combines sediment pre-filtration, carbon treatment, RO purification, and post-carbon polishing into a single compact cabinet, eliminating the need for separate units and saving valuable floor and counter space.
Intelligent LED Control Panel
Color LED display with real-time dual TDS monitoring (raw water & purified water in ppm), four-stage filter life indicators (PP, UDF, RO, T33), and system status lights (feed water, production, tank full, flushing, water shortage) for complete visibility and easy maintenance.
Dual Pressure Gauges
Built-in raw water pressure gauge and operating (RO) pressure gauge allow operators to quickly assess feed water conditions and system performance, enabling early detection of filter clogging or pump issues.
High-Capacity Commercial Output
Equipped with a high-flow RO membrane and booster pump, delivering stable purified water output suitable for high-demand commercial environments (400–1200 GPD configurable).
Premium Cabinet Build
Durable metal cabinet with a sleek dark-gray control panel and silver brushed-metal body, designed for commercial settings with a clean, professional appearance that fits any kitchen, break room, or service counter.
Easy Filter Replacement
Tool-free, quick-access filter housing design allows fast, hygienic cartridge replacement without specialized technical staff, minimizing downtime and maintenance cost.
Auto Flush & Protection
Built-in automatic membrane flushing cycle extends RO membrane life; low-pressure protection (water shortage shutoff) and high-pressure tank-full shutoff ensure safe, unattended operation.
Low Noise Operation
Quiet booster pump and vibration-dampening design ensure unobtrusive operation in office, restaurant, and hospitality environments.
OEM/ODM Support
Fully customizable flow rates, configurations, branding, and cabinet colors to meet your specific market needs.
