Strainer - for threaded filter - 3"; 600 µm FIV.42 R

Product detailed description

Strainers for threaded filters are essential components in heating, plumbing and irrigation systems. They are installed in pipelines to capture solid particles and prevent them from entering sensitive equipment such as pumps, valves or heat exchangers. In residential and commercial buildings, these filters are commonly found in circulation systems, boiler circuits and water supply lines. Installers and service technicians regularly replace or inspect these filters to ensure system efficiency and prevent blockages.

Correct selection and installation of a strainer ensures that the filtration level matches the system requirements. A mismatch in porosity or connection size can lead to ineffective filtration or mechanical stress on the system. The IVAR 42R080 is specifically designed for use with the FIV.08412 filter type, ensuring compatibility and reliable performance in professional applications.

Technical parameters

Installation and connection

Installation of the IVAR 42R080 involves removing the old strainer from the threaded filter housing and replacing it with the new unit. The 3 inch threaded connection must be aligned with the filter body and tightened to the manufacturer’s specifications. It is important to ensure that the threads are clean and free from debris before assembly to prevent leaks or misalignment. A common mistake is over-tightening, which can damage the threads or the filter housing. Installers should also verify that the filter is correctly seated and that the sealing surfaces are intact.

Compatibility and accessories

The IVAR 42R080 is specifically designed for use with the FIV.08412 threaded filter type. It is not interchangeable with other filter models without verification of dimensions and specifications. When replacing the strainer, it is recommended to inspect the filter housing and sealing components for wear or damage. No additional accessories are required for installation, as the strainer is a direct replacement part.

Technical background for designers

The IVAR 42R080 operates as a mechanical strainer, capturing solid particles in the flow stream. The sieve material is selected for its durability and resistance to corrosion, ensuring long-term performance in water-based systems. The 600 µm porosity allows for the retention of particles larger than this size, preventing them from passing through the filter. The strainer is integrated into the system as part of the filtration stage, typically positioned upstream of sensitive components. The efficiency of the filter depends on the flow rate and the concentration of particulate matter in the system. Regular maintenance is necessary to prevent clogging and maintain hydraulic performance.

Service and operation

During operation, the strainer should be inspected periodically for signs of clogging or wear. A drop in system pressure or reduced flow may indicate that the filter requires cleaning. The strainer can be removed for cleaning or replaced entirely if the sieve is damaged. No specific service intervals are provided in the brief, but maintenance should be carried out according to the system’s operational requirements and the manufacturer’s guidelines.

Frequently asked questions

Can the IVAR 42R080 be used with other filter models besides FIV.08412?
It is specifically designed for the FIV.08412 filter type. Use with other models is not recommended without verifying compatibility.

What is the maximum particle size that the 600 µm sieve can retain?
The sieve retains particles larger than 600 micrometres, preventing them from passing through the filter.

Is the strainer suitable for high-pressure systems?
It is designed for standard pressure conditions typical of heating and plumbing systems. Specific pressure ratings are not provided in the brief.

Can the strainer be cleaned and reused?
Yes, the strainer can be removed and cleaned if the sieve is not damaged. Replacement is recommended if the sieve is worn or clogged.
