Aquatürk Inline CTO Filter

The dense porous block also retains fine particles down to 10 µm, reducing the load on the reverse osmosis membrane. Quick-connect stems allow tool-free installation and replacement.

Features

Compressed coconut shell carbon block
Reduces residual chlorine, taste, odour and organics
10 µm fine filtration reduces the load on the membrane
Tool-free, quick replacement with quick-connect stems
Sealed housing; no housing cleaning needed at replacement
Fits standard 2.5" inline filter positions

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.
* Label value (2,500 gal). Actual capacity depends on water quality, chlorine level and flow rate.

Operating Conditions

Operating pressure: 1.4 - 8 bar (20 - 116 psi)
Operating temperature: 4 - 38 °C (39 - 100 °F)
Maximum flow rate: 2.8 L/min (168 l/h)
Replacement interval: 9,462 L or 6 months max.

Materials and Construction

Filter media: Compressed carbon block
Carbon source: Coconut shell
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 at least 5 minutes until the water runs clear to remove carbon fines.

The filter is disposable and cannot be opened or washed. Replace it after 9,462 litres or every 6 months at the latest; replacing it together with the other pre-filters in the system is recommended. Do not use with microbiologically unsafe water or water of unknown quality without disinfection.
