GEL filter cartridge - 5"; 20 µm coiled fibre GEL.20 µm VLAKNO

Product detailed description

Single-use filter cartridges are essential components in water filtration systems for heating and plumbing installations. They are commonly used in residential, commercial and industrial buildings to ensure the quality of water in heating circuits, irrigation systems and domestic water supply. Installers and service technicians often replace these cartridges during routine maintenance or when system performance declines due to particulate accumulation. The GEL filter cartridge is designed for integration into standard 5-inch filter housings and is selected based on the required filtration grade and system compatibility.

Proper selection of a filter cartridge is crucial to ensure effective removal of suspended solids and to prevent damage to downstream components such as pumps, valves and heat exchangers. The filtration grade and material composition directly influence the system's efficiency and the frequency of cartridge replacement. The GEL filter cartridge is intended for use in systems where a 20 µm filtration level is sufficient to meet operational requirements.

Technical parameters

Installation and connection

The GEL filter cartridge is installed in a 5-inch filter housing using a push-fit or threaded connection, depending on the housing design. It is important to verify that the housing is compatible with the cartridge's dimensions and that the sealing surfaces are clean and undamaged before installation. A common mistake is the use of incompatible housing sizes, which can lead to leaks or improper sealing. Installers should also ensure that the system is depressurised and drained before replacing the cartridge to avoid water damage and ensure safety.

Compatibility and accessories

This filter cartridge is specifically designed for use with the GEL.DEPURA 3000 OT filter series. It is not compatible with other filter models that require different cartridge dimensions or filtration grades. When replacing the cartridge, it is necessary to ensure that the filter housing is in good condition and that the sealing gasket is intact. No additional accessories are required for standard installation.

Technical background for designers

The GEL filter cartridge operates on a mechanical filtration principle, where suspended particles are retained by the coiled cotton fibre matrix. The plastic tube provides structural integrity and ensures even flow distribution through the filter media. The coiled design increases the surface area, allowing for higher dirt-holding capacity and longer service life compared to flat media. The filtration efficiency is influenced by the porosity of the media, the flow rate and the particle size distribution of the incoming water. The material is resistant to common water contaminants and does not release fibres or other particles into the system.

Service and operation

As a single-use filter cartridge, the GEL model is not designed for cleaning and must be replaced when clogged or when filtration performance declines. There are no specified service intervals, and replacement should be based on system performance and visual inspection. During routine maintenance, technicians should check for signs of wear on the housing and ensure that the cartridge is properly seated and sealed. A drop in system pressure or reduced flow rate may indicate the need for replacement.

Frequently asked questions

Can the GEL filter cartridge be used in a 10-inch filter housing?
No, the cartridge is specifically designed for 5-inch filter housings and will not fit in larger sizes.

Is the GEL filter cartridge compatible with all IVAR filter models?
No, it is only suitable for the GEL.DEPURA 3000 OT filter series.

Can the filter media be cleaned and reused?
No, the cartridge is a single-use product and must be replaced when clogged or damaged.

What is the maximum particle size the filter can retain?
The 20 µm porosity ensures that particles larger than this size are retained by the coiled cotton fibre media.
