  • Multi-purpose filter system specifically for well water with fully automatic control Clack WS 1 in a cabinet housing, removes: total hardness, dissolved iron, dissolved manganese, organics and ammonium - suitable capacity for every water consumption

Performance class (capacity)

The capacity depends on your water hardness and water consumption. You can determine the capacity using our capacity calculator or this rule of thumb:

Water hardness rule of thumb
Medium-hard water (8–14 °dH) Number of people x 7.5
Hard water (14–21 °dH) Number of people x 10
Very hard water (over 21 °dH) Number of people x 12.5

Example (4 people with a water hardness of 20): 4 x 10 = 40

PENTA Multi-Filter System

  • Multi-purpose filter system specifically for well water with fully automatic control Clack WS 1 in a cabinet housing, removes: total hardness, dissolved iron, dissolved manganese, organics and ammonium - suitable capacity for every water consumption

PENTA Multi-Filter System: One filter – five solutions

The Penta multi-filter system is particularly suitable for well water, e.g., for single-family homes or small consumers.

Total hardness, dissolved iron, dissolved manganese, organic matter, and ammonium – the ALFILTRA Penta multi-filter system can remove all of these simultaneously. This fully automatic, single-column multi-filter system with an electronic, water-flow-controlled CLACK WS1 valve is simply installed upstream of your existing water supply. The system uses the proven ion exchange process to remove iron, manganese, organic matter, ammonium, and water hardness.

When its capacity is exhausted, the system regenerates itself automatically using the stored salt supply. An integrated safety float valve protects the salt container from overflow, and the fiberglass-reinforced pressure tank withstands pressure surges of up to 16 bar.

Overview:

  • Fully automatic, water-volume-controlled MULTI filter system with Clack WS 1 control unit in a cabinet housing
  • Automatic water interruption during regeneration (via No-Hardwater-Bypass*)
  • Safety float valve to protect against overflow
  • Connections: 1" threaded plastic fitting, professional quality
  • Fiberglass reinforced quality pressure tank
  • Regeneration phase can be set to nighttime.
  • Technology proven over decades
  • Plug & Play - The system arrives at your home pre-programmed.
  • Very easy assembly or with assembly service (available separately)
  • 2-year warranty (up to 7-year warranty with annual maintenance)
  • The system must be installed in a frost-free room.

Scope of delivery:

  • Ready-to-use multi-filter system model PENTA Basic with control valve CLACK WS1
  • No-hardwater bypass (regeneration shut-off valve)
  • Special high-performance ion exchange resin (already filled into the pressure tanks)
  • Safety float valve integrated into the salt container
  • Operating and programming instructions

Please note: This system is supplied without connection parts and without a wastewater hose. These can be found above under Accessories. You will also find an installation service there, should you require it. The system can pump wastewater to a height of up to 2 meters. The use of a backwash filter is recommended to prevent damage to the iron filter system.

If you would like to learn more about the functionality and advantages of the PENTA multi-filter system, please visit our information pages on iron removal.

* No-Hardwater Bypass: The No-Hardwater Bypass ensures that the water supply is interrupted during regeneration. Regeneration takes approximately one hour. If an uninterrupted water supply is required, we recommend the Penta Duplex Multi-Filter System.

Variant: Penta Basic 50 Eisenfilteranlage
So far, so good. Unfortunately, the steering head is damaged with the bottle...
So far, so good. Unfortunately, the control head is permanently attached to the bottle, making it impossible to change the filter material.
