FCPP5BB20 WodaRO Big Blue 20" string filter 5 microns

Big Blue 20" string wound cartridge for effective pre-filtration

The string-type sediment cartridge has been designed to remove fine fractions of solid contaminants from water. It is a solution intended for use where protection of the water installation and reduction of deposits in devices that come into contact with water are important.

With a filtration rating of 5 microns, the cartridge effectively captures typical mechanical contaminants present in water, helping maintain better operating conditions for subsequent filtration stages and protecting system components from premature wear.

Construction and operating principle

Model FCPP5BB20 is made of pure polypropylene fiber wound onto a filtration core. This design is no accident — it ensures a gradual increase in the density of the filter material toward the center of the cartridge.

In practice, this means more effective retention of contaminants on successive layers of the material. Water flowing through the cartridge is cleaned of suspended solids and mechanical deposits, which supports stable system operation and improves protection of devices connected to the water network.

What contaminants does the cartridge remove?

• sand,
• sludge,
• silt,
• rust.

Cartridge application

The cartridge is intended for pre-filtration of water, meaning it retains suspended solids and mechanical deposits before further treatment stages. It is an important element wherever water may contain fine solid particles that negatively affect the durability of the installation.

The cartridge can be used as a protective element for domestic water treatment systems, standard utility installations, and advanced filtration solutions. It also works well as the first stage before devices such as an osmosis filter, reverse osmosis, or reverse osmosis filter, as it helps limit the flow of mechanical contaminants to more precise membranes and components.

Main benefits

• effective removal of fine solid contaminants from water,
• protection of the water installation against mechanical deposits,
• lower risk of damage to household appliances,
• support for protecting heating equipment,
• solid polypropylene fiber construction,
• gradient filtration density structure toward the core,
• suitability as a pre-filtration stage in larger water treatment systems.

Why choose a polypropylene string wound cartridge?

Polypropylene is a material commonly used in mechanical water filtration due to its good durability in use and effectiveness in retaining solid contaminants. In a string wound design, an additional advantage is the way the fiber is wound around the core, which supports multilayer particle capture.

This makes the cartridge well suited for applications requiring a durable, simple, and effective pre-filtration element. In domestic and technical systems, it can serve as the first barrier against mechanical contaminants, relieving the remaining system components.
