GEL filter cartridge - replacement; for GEL.DEPURA CYCLON XL; 150 µm; GEL.150 µm

Product detailed description

This replacement filter cartridge is typically installed in domestic and commercial drinking water systems where particulate contamination control is required. It is commonly used in pre-treatment stages for boilers, heat exchangers, and point-of-use filtration systems. Installers often integrate this unit into new build projects or retrofit older systems to improve water quality and prolong equipment lifespan.

The filter is suited for applications where periodic manual cleaning is acceptable. It is particularly useful in areas with moderate levels of sediment and particulate matter in the water supply. The design allows for straightforward maintenance without the need for complex tools or electrical connections.

Technical parameters

Installation and connection

Installers should ensure that the flange sizes match the system’s piping configuration—DN 65 or DN 80. The unit requires a secure, leak-free connection to the water supply line. A direct connection to the drainage system is recommended to facilitate manual backwash operations. Before installation, verify that the filter head and housing are free from manufacturing defects and that all seals are intact. Common installation errors include incorrect flange alignment and failure to connect the drain line, which can lead to poor performance and blockages.

Compatibility and accessories

This filter cartridge is specifically designed for the GEL.DEPURA CYCLON XL system. For full functionality, it must be used in conjunction with the corresponding filter housing. Additional components such as mounting brackets, sealing gaskets, and drain hoses may also be required depending on the system layout. Ensure that all components are sourced from the same manufacturer to maintain system integrity and compliance with safety standards.

Technical background for designers

The filter operates by allowing water to pass through a nylon filter element with a 150 µm pore size. Larger particles are retained within the filter media, while clean water flows through. The filter head is made of polypropylene (PP), and the filter body is constructed from SAN (styrene acrylonitrile), both of which offer resistance to corrosion and chemical degradation. The system integrates easily into existing pipelines and can be placed either vertically or horizontally. The service life of the filter depends on the frequency of manual cleaning and the concentration of suspended solids in the feed water.

Service and operation

Periodic manual backwashing is necessary to remove accumulated debris from the filter element. This process involves opening the drain valve and releasing trapped particles into the waste line. After backwash, inspect the filter housing for signs of wear or damage. Replace the cartridge when the flow rate drops significantly or if visible clogging occurs. No specific service intervals are provided in the technical documentation.

Frequently asked questions

Can this filter be used in closed-loop hot water systems?
This filter is suitable for open drinking water systems. Its maximum operating temperature of +40 °C limits its use in closed-loop hot water applications.

Is the filter compatible with chlorinated water supplies?
The materials used in the filter construction are resistant to chlorinated water, making it suitable for municipal water supplies treated with chlorine.

Can the filter be installed in reverse flow direction?
It must be installed according to the manufacturer’s flow direction indication. Reversing the flow could reduce filtration efficiency and cause premature clogging.

What is the recommended frequency for manual backwash?
The frequency depends on the level of particulate in the incoming water. When flow restriction is observed, initiate a manual backwash procedure to restore performance.
