  • Two-column multi-purpose filter system for well water or water from private supply with fully automatic control Clack WS 1 in a cabinet housing, removes: total hardness, dissolved iron, dissolved manganese, organics and ammonium - the right 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 DUPLEX Multi-Filter System

  • Two-column multi-purpose filter system for well water or water from private supply with fully automatic control Clack WS 1 in a cabinet housing, removes: total hardness, dissolved iron, dissolved manganese, organics and ammonium - the right capacity for every water consumption

PENTA Multi-Filter System: One filter – five solutions

The Penta Duplex multi-filter system is particularly suitable for well water, e.g., for apartment buildings or large-scale consumers.

Total hardness, dissolved iron, dissolved manganese, organic matter, and ammonium – the new Penta Duplex Multi-Filter System and the Penta Multi-Filter System can remove all of these simultaneously. This fully automatic, two-column multi-filter system with an electronic, water-flow-controlled CLACK WS1 Twin control valve is simply installed upstream of your existing water supply. The system removes iron, manganese, organic matter, ammonium, and hardness using the proven ion exchange process. When its capacity is exhausted, the system regenerates itself automatically using the stored salt. 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.

  • Fully automatic, water-volume-controlled duplex multi-filter system with Clack WS 1 Twin control unit
  • Uninterrupted water supply
  • Safety float valve to protect against overflow
  • Delivery of individual components on pallets

  • Power supply 230 V / 50 Hz, power consumption approx. 5 watts
  • Plug & Play - The system arrives at your home pre-programmed.
