Iron and hardness reduction filter Ecosoft FK 3672CE2 (Ecomix® A)

Article : FK3672CE2
  • Eliminate 5 major water contaminants  ?
  • Up to 18 m³ pure water per hour  ?
  • Low expluatation costs  ?
  • Filter media life 7-10 years  ?
  • Fully automated process  ?
  • Protection against network interruptions  ?

Ecosoft FK 3672 CE2 filter is an independent filter intended for reduction of iron, manganese, hardness, ammonium and organic matter in water. The filter is applicable for objects with a capacity below 7.5 m3/h.

The filter vessel is filled with the Ecomix® advanced softening media and supplied with a multifunctional control valve and a brine tank for system regeneration.

Model features

The filter of complex purifying gives significant savings on the purchase and maintenance of water treatment system. One filter Ecosoft FK 3672 CE2 replaces several specialized units. The system operates continuously in the automatic mode, and its maintenance is limited only by the timely addition salt tablets.

Key advantages

  • Fully automatic and noise-free.
  • Uninterrupted delivery of pure and soft water.
  • Durable and efficient operation for no less than 5 years.
  • Cost-effective salt consumption and low volume of discharge.
  • Quality guaranteed by the international CE and ISO certificates.

Benefits of using filtered water

  • Pure water with no odours in every tap, shining sanitary ware, and utensils.
  • Significant savings on detergents – up to 50%.
  • Longer service life of equipment with heating elements (washing machine, dishwasher, boiler, and kettle).

Device and filter operation

The system consists of two main modules - a vessel with filter media and a salt-solvent tank. The cylinder is made of a corrosion resistant polymer composite material. Inside, there is Ecomix® filtering mixture, which consists of several components.

Each component of the filter filling is designed to neutralize or retain certain different kinds of harmful impurities. As a result, integrated water filtration is carried out in one stage. Purified water has good organoleptic characteristics and can be used for any household needs. It is completely safe for skin and hair, and also does not form scale on the heating elements of the devices.


The service life of the filter media is 7-10 years. This is possible due to the regenerative ability of the Ecomix®. The recovery of the filtering properties of the media is carried out by washing it with tableted salt solution. As well as water purification, the regeneration process is carried out automatically.
After exhaustion of filter media resource operating valve balloon of the filter to the regeneration mode. Regeneration takes place with purified water, which is supplied from the working part of the filter, and takes place in 5 stages, which are clearly programmed and carried out by the valve independently.

Control Automation

The unique control valve is a product developed by Ecosoft and produced by Clack Corporation (USA). It provides filter’s independent service, keeps constant reserve of purified water and doesn’t require any special attention.

Who are the users?

The system of complex cleaning Ecosoft FK 3672 CE2 fits for facilities with capacity less than 18 m³. The unit can be used to purify and soften borehole and tap water.

The filter is connected to the cold water supply system, effectively purifies the water and independently controls all the processes of its work.
Pre-purified from mechanical impurities water enters the filter vessel filled with Ecomix® filter media. The filter media consists of five components that successively trap iron, manganese, organic impurities and hardness salts. Purified water through the central pipe of the case is supplied to the consumer.

When the resource of the filter media ends, the filter independently goes on regeneration, but only at a time when water consumption is minimal, so it won't deprive you of access to purified water. In addition, the control valve remembers the intensity of your water consumption at different times and is adapted so that clean water is available even at peak consumption, for example, on weekends.

Regeneration takes place in 5 stages

  • Flushing with back flow of water. At the same time, iron and manganese compounds are washed out of the filter media.
  • The brine solution is fed from the tank into the filter vessel, passes through the Ecomix® and washes away hardness salts and organic matter from it. Impurities with the remnants of the solution are discharged into the sewage.
  • Short backwash. Once again, loosens the load and washes away the remnants of the salt solution.
  • Flush the Ecomix® with a direct stream of water to lay layers of media in the desired order.
  • Fill the brine tank with water to dissolve the tableted salt and prepare the solution for the next regeneration.

Thanks to the use of a multifunctional valve, the filter does not require constant attention. The only important task connected to maintenance for customer is timely stocking of the salt. It will ensure efficient regeneration of the filter media and thus durable filter service life and water quality.
If any problem arises, the valve will inform about the problem at the display with a text message containing contact information of service center.
