Caleffi DIRTMAG® 3/4"

Product detailed description

Dirt separators with magnetic filtration are commonly used in heating, plumbing and irrigation systems to prevent sediment and ferromagnetic particles from entering sensitive components such as pumps, valves and heat exchangers. This model is suited for installation in residential, commercial and industrial buildings where water quality management is essential. It is typically integrated into closed-loop systems, domestic hot water circuits and circulation lines. Installers working on pipe systems with potential particulate contamination will find this device effective for maintaining long-term system performance.

The unit is designed for straightforward integration into existing systems and requires minimal space due to its compact dimensions. It operates within a wide temperature range and is suitable for both new installations and retrofitting. Its construction ensures durability under normal operating conditions and allows for regular cleaning and inspection without system shutdown.

The maximum operating pressure of 3 bar indicates the upper limit for safe operation under normal conditions. The temperature range of 0 – 90 °C defines the limits for cold and hot water applications. These parameters are essential for proper sizing and system compatibility, ensuring the separator functions effectively without risk of mechanical failure.Installation and connection The CALEFFI DIRTMAG® 3/4 inch is connected using standard internal threading, suitable for 3/4 inch pipe systems. Prior to installation, ensure the system is depressurised and the separator is oriented correctly for either vertical or horizontal flow. A hose connection is provided for manual draining of accumulated debris. Installers should verify that the direction of flow aligns with the arrow marked on the body. Common mistakes include incorrect orientation or failure to secure the drain connection properly, which can lead to leaks or ineffective sediment removal. Always perform a visual inspection after installation to confirm tightness and correct positioning.Compatibility and accessories This dirt separator is compatible with standard 3/4 inch threaded pipe systems and is suitable for integration with a range of pumps, circulation systems and heat exchangers. For optimal performance, it is recommended to pair with a pressure gauge and a shut-off valve for isolation during maintenance. No additional accessories are required for basic operation, but a drain hose may be needed for manual emptying.Technical background for designers The CALEFFI DIRTMAG® combines mechanical and magnetic filtration principles. As water flows through the chamber, larger particles settle at the bottom while magnetic components attract ferrous debris. The technopolymer body resists corrosion and maintains structural integrity over time. The design allows for continuous operation while capturing contaminants without restricting flow. The operating temperature range ensures suitability for both heating and non-heating applications. Long-term efficiency depends on regular draining and absence of chemical additives that could degrade the polymer casing.Service and operation Periodic draining of the collected sediment is necessary to maintain performance. The drain valve allows for manual emptying without interrupting system operation. There are no defined service intervals provided in the technical data, but it is advisable to inspect and clean the unit at least once per year, depending on water quality and system usage. Check for signs of wear or blockage in the drain port and ensure the internal chamber is free of obstructions.Frequently asked questions
