Under-Sink UF System
These are complete ultrafiltration units that sit under the sink or on the wall, rather than a bare membrane element. Both models put a 0.01 micron hollow fiber membrane behind PP and carbon stages.
ZH-A uses a 304 stainless steel body with five interchangeable cartridges (PP, RFC, CTO, UF, T33) and a pressure gauge, rated 220 L/h. ZH-B is the simpler three-stage build — PP, CTO and UF — in transparent reinforced housings at 350 L/h.
Neither unit needs electricity, and both take standard interchangeable cartridges, so a distributor can stock one housing and vary the media.
Under-Sink UF System models (2)

ZH-A 5-Stage Stainless Steel UF System
Wall-mounted or under-sink five-stage ultrafiltration system in a 304 stainless steel body. PP, RFC, CTO, UF and T33 cartridges run in series at 0.01 micron and 220 L/h, with a pressure gauge and interchangeable cartridges.
- 0.01 μm filtration
- 220 L/h flow rate
- 304 stainless steel housing
- 5-stage interchangeable cartridges

ZH-B 3-Stage Transparent Under-Sink UF System
Three-stage under-sink system with transparent reinforced housings: PP cotton, carbon block and a hollow fiber UF membrane at 350 L/h. The clear housing lets an end user see cartridge condition without opening the unit.
- 0.01 μm UF stage
- 350 L/h flow rate
- Transparent reinforced housing
- 3-stage PP + CTO + UF
