S-SF/UF-4 Commercial Ultrafiltration Water Purifier
Product Overview
The S-UF-4 is the mid-range configuration of the ULTRA CF+UF commercial ultrafiltration series, delivering a four-filter purification process. A 5µm PP sediment pre-filter captures large particulate impurities; water then enters the core ACF + UF cartridge — the activated carbon fiber (ACF) layer deeply adsorbs residual chlorine, odors and heavy metals, while the 0.01µm hollow-fiber ultrafiltration (UF) membrane physically retains bacteria and viruses. Finally, a post-activated-carbon cartridge polishes the taste, delivering clean, refreshing water ready for equipment use or direct drinking. The unit is fitted with dual pressure gauges at the inlet/outlet of the main filter zone for precise differential monitoring. Recommended for bubble tea shops, specialty coffee and fresh-juice bars with moderate-to-high water demand.

Key Features
- All-in-one four-filter architecture — PP pre-filter + ACF carbon fiber + UF membrane + post carbon, full purification in one unit
- Hollow-fiber UF membrane (0.01µm) — physically retains bacteria, viruses, cysts and colloids without chemicals
- ACF carbon-fiber cartridge — efficiently removes residual chlorine, chloramines, antibiotics, odors and heavy metals, protecting the UF membrane
- 5µm PP pre-filter — traps sediment, rust and eggs, extending the life of downstream cartridges
- Post-carbon polishing — optimizes taste and odor to direct-drinking / equipment-supply quality
- Quick-connect modular manifold — tool-free cartridge change in ~2 minutes, minimal maintenance
- Dual pressure gauges — monitor inlet/outlet differential, pre-warn cartridge replacement
- Wide commercial use — bubble tea shops, specialty coffee, juice bars, restaurant chains, hotel kitchens
- OEM/ODM available — brand logo, shell color, manifold interface and certification files customizable
Filtration System
| Stage | Filter Type | Function | Service Life |
|---|---|---|---|
| Pre-filter | PP Sediment Filter (5µm) | Traps sediment, rust, eggs and other large particles; protects downstream cartridges | 3 months |
| Main ×2 | ACF + UF Membrane (parallel) | Carbon fiber removes chlorine, heavy metals & odor; 0.01µm UF membrane retains bacteria, viruses & colloids; two membranes in parallel raise instantaneous flow and extend each cartridge's service life | 12 months |
| Post | Post Activated Carbon (GAC) | Deeply optimizes taste and odor to direct-drinking quality | 9 months |
UF Membrane Precision
Filtration rating: 0.01 µm — physical retention, no chemical dosing. The UF membrane retains:
- Bacteria & E. coli (retention rate >99.99%)
- Viruses & bacteriophages
- Giardia & Cryptosporidium cysts
- Colloids, rust and turbidity
- Suspended solids and macromolecular organics
