Sediment filter Ecosoft FP 1665

Article : FP1665CT
  • No precipitation sludge and sand in the sink and bath   ?
  • Natural, eco-friendly filter media  ?
  • Low operating costs  ?
  • Easy maintenance  ?

The sediment filter FР 1665 is generally intended for water purification removing sediment impurities (silt, sand, rust, scale).

Model features

The filter Ecosoft FP 1665 CT is filled by high-quality media Filter-Ag® (Clack Corporation, USA). The filter is also used as the first stage of water purification before softening filters, complex purifying, removal of chlorine and hydrogen sulfide to ensure their normal and effective operation.


What are the advantages?

  • Lack of sediment silt and sand on the surface of the bath and in the sink.
  • Full automation of the filter.
  • Reliable and efficient work for at least 5 years*.
  • Longer service life of household appliances, plumbing and heating systems.
  • Quality assurance (confirmation by international certificates of CE and ISO).

*Subject to proper operation and timely replacement of filter media.

Filter construction and operation

The system consists of a corrosion-resistant vessel filled with high-quality sorption media Filter-Ag®, and a control valve. In the upper part of the cylinder the valve is attached, with elements of the drainage-distribution system.

Water flows into the filter vessel, passes through a layer of filtering media that effectively inhibits mechanical impurities. The purified water comes to the consumer through the central pipe of the vessel.

The unit is connected to the cold water supply, sewage and electrical network.


After exhaustion of the filter media resources, the filter independently switches to regeneration mode. The reverse flow of water passes at high speed through the layer of media and washes out all impurities from the surface of the carbon, after that the water is discharged into the sewer system. Then the filter switches to purify mode.

Who are the users?

The capacity of the Ecosoft FP 1665 CT filter is up to 1.55 m³/h, which allows you to provide pure water for a house or apartment with up to 10 residents. The unit is suitable for cleaning borehole and tap water.

After treatment, the water can be used safely for washing and dishwashers, hand washing and home cleaning.

The filter is connected to cold water supply. Water enters the filter vessel and goes through the layer of the filter media, which effectively reduces sediment. Purified water is delivered to the consumer through the riser pipe of the filter vessel.


When the filter is exhausted, it automatically switches to regeneration mode in order to regenerate the operational characteristics of the filter media.

At the prescribed time the control valve shifts the system into regeneration mode. For the consumer’s convenience, the system is regenerated during times when water is not being consumed. During the regeneration the filter is backwashed at high speed, the water stirs and cleans the surface of filter media, washing out all the impurities, and then is discharged into the drain. After this the system can be used for water purification again. Untreated feed water is used for the 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 display a text message about the problem.
