WATER FILTER PRE-FILTER BODY 1'' THREAD 3-STAGE + CARTRIDGES SET

3-STAGE 1" In-line Water Filter with 10" Cartridges + Wrench + Flow Bracket

This is a complete pre-filter that is perfectly suited for domestic water systems.

How 3-stage filtration works:

1️⃣ Foam filter – traps solid particles (sand, rust, suspended solids) - protects subsequent filtration stages

2️⃣ BLOK carbon filter – chlorine adsorption, improved water taste and odor

3️⃣ UDF carbon – completes the purification process and supports the bacteriostatic effect

✅ Main benefits:

• Effective protection of the system and devices against sand, silt, rust, and chlorine
• 10" standard – wide availability and low operating costs later on
• 3-piece housing – reliable sealing and quick cartridge replacement
• Transparent housing bowls – visual contamination control
• Air release button – easy, clean start-up after installation
• Solid materials, assembled in the EU – durability and trouble-free operation
• 1" female threads – compatibility with typical domestic installations

✅ What’s in the set:

- Triple 1" in-line housing (1" female-thread inlet/outlet)

- 3 x 10" filter cartridges:

• foam – mechanical filtration (sand, silt, rust)
• carbon block – chlorine reduction, improved taste and odor
• UDF (granular carbon) – additional sorption and bacteriostatic effect

- Mounting plate/bracket

- Housing wrench

- Mounting screws

✅ Application:

At the cold-water inlet to the house (as a pre-filter) or before a selected device: boiler, washing machine, dishwasher, water softener, treatment station

For mains water and well water (as a pre-treatment stage)

⚙️ Technical parameters:

• Connections: 1" x 1" female thread
• Cartridge size: standard 10"
• Maximum flow: up to approx. 4000 l/h (depending on cartridges and water quality)
• Operating pressure: recommended up to 6 bar
• Structural resistance: up to approx. 8 bar
• Water temperature: 2–45°C
• Unit dimensions: approx. 46 cm (W) x 32 cm (H)

Installation – simple and without surprises:

1. ️Shut off the main valve, secure the work area
2. Attach the mounting bracket and level it
3. Connect the housing, maintaining the flow direction (cold water)
4. Insert the cartridges into the bowls and tighten the rings with the wrench
5. Slowly turn the water on, vent with the button, and check for leaks

Operation and servicing:

• Check contamination through the transparent bowl
• Approximate intervals (depending on water quality and water consumption): foam: every 1–3 months, carbon block and UDF: every 3–6 months
• Replace earlier if pressure drops or taste/odor worsens

⚠️ Install on cold water only; protect from frost

Safety and best practices:

⚠️ After first start-up, flush the system for several minutes

⚠️ In case of large pressure fluctuations, a pressure reducer and service bypass are recommended

⚠️ Carbon cartridges do not replace disinfection in the event of microbiological contamination of the water

❓ Do cartridges other than the ones included in the set fit?

Yes. The housing accepts any standard 10" cartridge: mechanical cartridges (various micron ratings), carbon cartridges (block, GAC), and specialized cartridges (e.g. iron removal) - provided the manufacturer offers a 10" version.

❓ Is the set suitable for well water?

Yes, as a pre-filter. If iron/manganese levels are exceeded, turbidity is very high, or there is a hydrogen sulfide smell, it is worth adding appropriate media/stations as further stages.

❓ Can it be installed horizontally?

Vertical installation (head at the top) is recommended, as it ensures proper flow, easy cartridge replacement, and effective venting.

❓ What pressure is safe for filter operation?

Recommended working pressure is up to 6 bar. Structurally, the set withstands up to approx. 8 bar, but for longevity and safety, please stay within 6 bar and install a pressure reducer.

❓ What is the actual flow through the set?

Up to approx. 4000 l/h with fresh cartridges and good water parameters. Flow depends on cartridge contamination and system pressure.

❓ When should cartridges be replaced?

When pressure in the system noticeably drops, water taste/odor worsens, or the approximate service life has expired. In harsher conditions (well water, high usage), replacements may be needed more often.

❓ Does the transparent bowl cause algae growth?

If the filter is exposed to direct sunlight, please consider a cover or installation in a shaded location. In typical boiler rooms/recesses, this problem does not occur.

❓ Does the set remove limescale from water?

This set does not soften water - it primarily provides mechanical protection and chlorine reduction. Water softening requires a separate station (ion-exchange softener).

❓ Do carbon cartridges remove bacteria?

Activated carbon improves organoleptic properties and has a bacteriostatic effect, but it does not replace disinfection. If there is a microbiological risk, additional methods should be used (e.g. UV after filtration).

❓ Can the cartridge be flushed and reused?

Foam mechanical cartridges can sometimes be rinsed for short-term refreshment, but regular replacement is recommended for full effectiveness. Carbon cartridges are not regenerated - replace them with new ones.

❓ Is the set suitable for low-temperature operation?

No. The minimum operating temperature is approx. 2°C. Protect from freezing - frost may damage the housing and seals.

❓ How should the system be prepared for installation?

It is recommended to include shut-off valves before and after the filter and a service bypass so that the entire system does not need to be shut down when replacing cartridges.

❓ Can water be temporarily milky after installation?

Yes, this is typical aeration after start-up. The effect disappears after a few minutes of flushing and venting with the button on the head.

Why choose it:

✅ Complete set, 10" standard, stable operating parameters, and simple servicing

✅ Real protection for fixtures, faucets, aerators, household appliances, and further water treatment stages

✅ Fast results at home: cleaner water, less mechanical sediment, better taste and odor
