Sediment Filter Trap kfa² 6/4" 720-000-40 — inlet filter for debris and sand

Sediment Filter Trap kfa² 6/4" is an inline inlet filter designed to capture sand, rust and mechanical debris from water supply systems. The unit fits 6/4" connections and is intended for installation on supply lines to reduce particulate load before water reaches boilers, pumps, valves and fixtures. The filter body provides straightforward access for periodic flushing and maintenance to remove collected sediment without complex disassembly.

Advantages

The filter removes coarse particles and sediments that can cause wear and blockages in downstream equipment, helping maintain the efficiency and service life of heating and plumbing components. Its inline design and 6/4" compatibility allow easy integration into existing supply lines, while the serviceable body enables simple flushing to clear trapped debris. The construction offers reliable hydraulic performance with minimal pressure loss when installed correctly.

Suitable for

• Prevention of sand and rust ingress in central heating systems and boilers
• Protection of circulation pumps and control valves in hydronic installations
• Use on domestic and commercial water supply lines to protect fixtures and appliances
• Applications where periodic flushing access is required to remove accumulated sediment

Key specifications

• Connection size: 6/4" inline fitting suitable for standard supply lines
• Function: mechanical filtration of sand, rust and coarse particulate matter
• Maintenance: serviceable body with flushing capability to remove collected sediment
• Intended placement: inlet/supply line installation upstream of sensitive equipment
• Flow behaviour: designed to minimise pressure drop while capturing debris

How to use

Install the sediment filter on the supply line in the position recommended for inlet protection, ensuring correct flow direction through the unit. Securely connect to compatible 6/4" fittings and, after installation, check for leaks at joints. For routine maintenance, isolate the section of the system if needed, open the service or drain port and flush the filter body until expelled water runs clear. Reassemble and restore system pressure following the manufacturer’s recommended procedures.

Usage recommendations

Perform visual inspections and flushing at regular intervals based on water quality and system usage; more frequent checks are advisable where water contains high sediment levels. Use compatible sealing materials and follow local plumbing codes during installation. If persistent fouling or pressure loss occurs, inspect upstream sources and consider additional pre-filtration or professional system assessment.
