Filter cartridge - 1 µm; 20" IVAR.FR-N

Product detailed description

This filter cartridge is commonly used in domestic and commercial water filtration systems, particularly in applications where fine particulate removal is essential. It is often found in pre-filtration stages of boiler feedwater systems, heat pump circuits, and general water treatment systems. Installers and technicians typically handle these cartridges during routine maintenance or when replacing worn components. The design ensures compatibility with standard filter housings and supports integration into both new and existing systems.

The cartridge provides mechanical filtration of suspended solids down to 1 µm, making it ideal for removing fine particles such as sand, rust, and scale. Its disposable nature simplifies replacement and ensures consistent filtration performance over time. The operating temperature limit of +50 °C makes it suitable for warm water applications but not for steam or high-temperature systems. The PN 8 pressure rating ensures safe operation under normal hydraulic conditions in most residential and light industrial settings.

Technical parameters

Material	100% PP, hot air cross-linked PP (MELT BLOW)
Operating temperature	+50 °C
Nominal pressure	PN 8
Code	IVAFRN200001
Brand	IVAR

The operating temperature limit of +50 °C means the cartridge is suitable for non-heated or mildly heated water systems. The PN 8 pressure rating indicates it can handle up to 8 bar of continuous working pressure, which is standard for most low-pressure water systems. These parameters are essential for proper sizing and selection, ensuring the cartridge functions safely and effectively within the intended system conditions.

Installation and connection

To install the filter cartridge, first ensure the system is depressurised and the water supply is turned off. Remove the old cartridge and inspect the housing for damage or wear. Insert the new cartridge into the housing, ensuring it fits snugly and aligns with the flow direction indicated on the housing. Secure the housing cover and reconnect the water supply. Always verify the correct filter size (3/4 inch or 1 inch) and confirm the inner/outer diameter of the liner is 28/63 mm to avoid improper fit. Common installation mistakes include incorrect orientation of the cartridge, failure to depressurise the system before handling, and using incompatible housing sizes. These errors can lead to leaks, reduced filtration efficiency, or premature cartridge failure. Always double-check the housing specifications and follow the manufacturer’s installation guidelines.

Compatibility and accessories

This filter cartridge is specifically designed for use with filter housings of size 3/4 inch and 1 inch. It is compatible with standard filter systems that accept 20 inch-length cartridges. When ordering, ensure that the filter housing matches the specified dimensions and thread types. No additional accessories are required for basic installation, though a wrench may be needed for securing the housing. This product is not listed as compatible with any other specific models or accessories.

Technical background for designers

The cartridge operates on a mechanical filtration principle, trapping particles larger than 1 µm on the surface and within the depth of the melt-blown polypropylene media. The melt-blown process creates a dense, uniform structure that provides consistent filtration performance while minimising pressure drop. Polypropylene is chemically inert and resistant to most common waterborne contaminants, including chlorine and mild acids, making it suitable for potable and non-potable water systems. The cartridge integrates into the system via standard filter housings and is typically placed upstream of more sensitive components such as pumps, valves, or heat exchangers. The service life and efficiency depend on the quality and quantity of particulates in the water, as well as the frequency of maintenance. High particulate load or poor water quality can reduce the effective lifespan of the cartridge.

Service and operation

As a disposable filter, this cartridge is not designed for cleaning and must be replaced once it becomes clogged or loses filtration efficiency. Regular inspection of the system for reduced flow or increased pressure drop can indicate the need for replacement. No specific service intervals are provided in the brief; however, routine checks should be performed according to the system requirements and water quality conditions. Always replace the cartridge with a new one of the same specification to maintain system performance.

Frequently asked questions

Can this filter cartridge be used in reverse flow?
No, the cartridge is directional and must be installed in accordance with the flow arrow marked on the housing. Reversing the flow can cause bypassing and reduced filtration efficiency.

Is this cartridge suitable for chlorinated water?
Yes, the polypropylene material is resistant to chlorine and other common water disinfectants, making it suitable for chlorinated water systems.

Can this filter be used in steam systems?
No, the maximum operating temperature is +50 °C, which is insufficient for steam or high-temperature applications. A higher-temperature-rated cartridge would be required for such systems.

Always operate within the specified pressure limits.
