Aquafilter FCPP20-L is a string wound 20" LONG filter cartridge designed for pre-filtration of water in domestic and utility installations. Made of polypropylene cord, it effectively captures mechanical impurities such as sand, silt, and rust with an accuracy of 20 microns. It is a practical water filter for LONG housings, supporting a water filtration system, water treatment, and protecting installations, heating equipment, and household appliances from deposits.
20" LONG sediment cartridge for mechanical filtration
The FCPP20-L model is designed to operate in LONG-type housings as a universal sediment cartridge for removing suspended solids and mechanical deposits. Its task is to capture particles present in the water before it reaches further installation components or subsequent treatment stages.
The cartridge retains all kinds of mechanical contaminants, including:
- sand,
- silt,
- rust,
- other deposits and suspended solids up to 20 microns in size.
Cartridge construction and operating principle
The polypropylene string cartridges from the FCPP series are made of pure polypropylene fiber wound around a filter core. This design is no coincidence — it ensures a gradual increase in the density of the filter material toward the center of the cartridge.
In practice, this means effective capture of mechanical contaminants throughout the entire filter structure, which supports efficient pre-filtration and enables operation at very high permissible water flow rates. This is one of the features that makes 20 µm accuracy such a common choice for a wide range of applications.
Use in water installations
Aquafilter FCPP20-L is mainly used as a pre-filtration element for a residential building or other utility facility. It is intended for use where effective protection of the installation against solid particles present in the water is required.
The cartridge helps reduce the risk of deposit buildup and can support safer operation of water-contact equipment, in particular:
- water installations,
- heating equipment,
- household appliances.
As a result, it works well as the first stage of water treatment wherever protection of fittings and equipment against the effects of sand, silt, or rust matters. This type of mechanical filtration is also sometimes used before more advanced solutions such as a reverse osmosis filter, osmosis filter, reverse osmosis, or an advanced reverse osmosis system.
The cartridge is intended for pre-filtration of mechanical contaminants. Regular replacement helps maintain filtration efficiency, proper water flow, and effective protection of the installation and equipment.
Main practical benefits
- designed for LONG 20" housings,
- effective removal of mechanical contaminants down to 20 microns,
- made of polypropylene string,
- construction that ensures an increase in filter density toward the core,
- broad use in domestic and utility installations,
- very high permissible water flow rates,
- protection of heating equipment and household appliances against mechanical deposits.
Operation and cartridge replacement
To maintain high filtration efficiency, the cartridge should be replaced according to the intensity of use and the degree of water contamination. The FCPP20-L model offers a service life of up to 18,000 liters or 3 to 6 months of operation.
More frequent replacement may be necessary in the case of water with a high level of mechanical suspended solids. A drop in flow rate or visible soiling of the cartridge are practical signs that the filter element is nearing the end of its effective service life.

FAQ
What is the Aquafilter FCPP20-L cartridge used for?
It is a sediment cartridge for mechanical water filtration. Its task is to retain contaminants such as sand, silt, rust, and other suspended solids that can burden the installation and water-operated equipment.
What contaminants does this cartridge remove?
The cartridge captures mechanical contaminants, in particular sand, silt, rust, and similar deposits up to 20 microns in size.
Which housings is the FCPP20-L model compatible with?
The model is designed for 20-inch LONG filter housings.
What material is the cartridge made of?
The cartridge is made of polypropylene string. The filter media consists of pure polypropylene fiber wound around a filter core.
How often should the cartridge be replaced?
The recommended service life is up to 18,000 liters or 3 to 6 months. Actual service life depends on water quality and the amount of mechanical contaminants present in the installation.
Is the cartridge suitable for whole-house pre-filtration?
Yes, this model is mainly used for pre-filtration in a residential building or other utility facility, especially where the installation needs protection against mechanical deposits.
Why is the string-wound design effective?
Winding polypropylene fiber around the core causes the filter density to increase toward the center of the cartridge. This design supports effective retention of contaminants and allows efficient operation at high flow rates.
Can this cartridge work before a reverse osmosis system?
Yes, this type of mechanical filtration is often used as an initial stage before solutions such as a reverse osmosis filter, osmosis filter, or reverse osmosis system, because it helps reduce the amount of deposits entering subsequent system components.
