Regnum Jaco Inline CTO Filter

The dense porous block also retains fine particles, reducing the load on the reverse osmosis membrane. Jaco-type fittings and elbows are screwed into the threaded ports at both ends to connect it to the unit.

Features

Compressed carbon block reduces residual chlorine, taste and odour
Compressed block of coal-based activated carbon
Fine filtration reduces the load on the membrane
Threaded (Jaco) connection for a secure, leak-tight fit
Sealed housing; no housing cleaning needed at replacement
Fits standard 2.5" Jaco inline filter positions

Applications

Residential reverse osmosis (RO) units
Under-sink and countertop water purifiers
Mains-fed (bottleless) water dispensers
Feed lines of refrigerators, ice and coffee machines
Office and small commercial treatment systems

Dimensions

A: Overall length (including threaded ports) · B: Outer diameter. Sealed (welded) housing; the filter cannot be opened and is replaced as a unit. Fittings and elbows are supplied separately.
* 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: Coal-based activated carbon
Housing: Plastic (typically PP), welded
Connection: 1/4" female thread (Jaco), both ends
Use: Disposable, sealed

Shut off the unit's water supply and open the faucet to relieve pressure.
Disconnect the tubing and unscrew the fittings and elbows from the used filter.
Wrap the fitting threads with PTFE tape and screw them into the new filter, observing the flow direction (IN → OUT).
Reconnect the tubing, 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 overtighten the fittings. Do not use with microbiologically unsafe water or water of unknown quality without disinfection.
