Regnum Inline UF Filter

The UF membrane does not retain dissolved salts, hardness minerals or dissolved gases, so the mineral content of the water is largely preserved. It is installed after the carbon filters for chlorine and organics, and operates without producing reject water.

Features

Hollow-fibre UF membrane with 0.02 µm pores
Physically retains suspended solids, turbidity and colloids
Does not retain dissolved salts or minerals
No reject water; no pump or electricity required
Tool-free, quick replacement with quick-connect stems
Fits standard 2.5" inline filter positions

Applications

Membrane-free UF purifiers
Under-sink and countertop water purifiers
Mains-fed (bottleless) water dispensers
Low-pressure, non-electric treatment applications
Office and small commercial treatment systems

Dimensions

A: Overall length (including connection stems) · B: Outer diameter. Sealed (welded) housing; the filter cannot be opened and is replaced as a unit. Flow direction is marked on the housing.
* Typical value (at 1.5 - 2 bar inlet pressure). Actual flow depends on pressure, water temperature and membrane fouling.

Operating Conditions

Operating pressure: 1.5 - 8 bar
Operating temperature: 2 - 38 °C (36 - 100 °F)
Nominal flow rate: 1.9 L/min (1.5 - 2 bar)
Replacement interval: 12 months max. or when flow drops

Materials and Construction

Filter media: Hollow-fibre UF membrane
Filtration type: Ultrafiltration, 0.02 µm pore size
Housing: Plastic (typically PP), welded
Connection: Quick-connect stems 4/6, both ends
Use: Disposable, sealed

Shut off the unit's water supply and open the faucet to relieve pressure.
Detach the used filter from its connection stems and remove it from its clip.
Connect the new filter, observing the flow direction on the housing (IN → OUT).
Slowly reopen the water supply and check the connections for leaks.
On first use, flush for a few minutes to rinse the membrane and line.

The filter is disposable and cannot be opened or washed. Replace it every 12 months at the latest or when flow drops noticeably; service life is shorter if pre-filters are not replaced on time. Do not use with microbiologically unsafe water without disinfection.
