## Long description

The Herz Water filter with pressure reducer DN20 (model 2301102) is an inline cold-water unit designed for ¾" (DN20) pipe connections. It combines mechanical filtration with an integrated pressure regulator to remove particulate debris and reduce excessive supply pressure. The compact assembly is intended for installation on the main cold-water line feeding fixtures, boilers and appliances, aiming to protect downstream equipment and stabilize system pressure.
Advantages
This Herz inline water filter provides simultaneous mechanical filtration and pressure reduction in a single compact body, reducing the need for separate devices. The filter element captures sediment and particulates to prevent clogging of valves, faucets and heating equipment, while the integrated pressure reducer ensures steady, safe operating pressure for connected appliances. The DN20 size suits standard ¾" domestic and light-commercial pipe systems, allowing straightforward retrofit or new-installation placement ahead of sensitive equipment.
Suitable for
 Protecting domestic boilers, water heaters and washing machines from sediment
 Stabilizing water pressure for bathroom and kitchen fixtures
 Pre-filtering cold-water supply in apartments, houses and small commercial installations
 Installation ahead of meters, valves and pressure-sensitive appliances
Key specifications
 Connection size: DN20 (¾") suitable for standard domestic piping
 Function: mechanical filtration combined with pressure reduction
 Application: inline cold-water use only
 Material: corrosion-resistant body materials suitable for potable water systems
 Flow orientation: inline installation with defined inlet and outlet
How to use
Install the Herz DN20 water filter with the correct flow direction indicated on the housing, on the cold-water main or branch supplying the protected fixtures. Shut off the water supply before installation, mount using compatible DN20 fittings and ensure secure sealing of threaded joints. Periodically access the filter element for inspection and cleaning or replacement according to operating conditions; follow local plumbing codes for installation and maintenance. Do not use the unit on hot water lines or for fluids other than potable water.
Usage recommendations
Place the filter upstream of boilers, softeners, meters or appliances to prevent sediment ingress and set the pressure reducer to match the recommended operating range of connected equipment. Regularly check the filter element for buildup and service it more frequently in areas with high sediment content to maintain flow and pressure stability.
