## Long description

CALEFFI dirt separator 3/4" x 18, model 545101 is a compact inline device engineered to remove solid particles and debris from hydronic heating and cooling circuits. Designed for domestic and light-commercial systems, this dirt separator captures contaminants before they reach pumps, control valves and heat exchangers, helping to maintain system performance and reduce the frequency of maintenance interventions.
Advantages
The CALEFFI dirt separator integrates a sizable collection chamber and an efficient internal separation element to retain suspended particles while allowing normal fluid flow. Its straightforward inline configuration supports quick installation in return or supply lines, and the unit is compatible with standard 3/4" pipe connections. By preventing blockages and abrasion in mechanical components, the separator contributes to longer component life and more stable system operation.
Suitable for
 Domestic central heating systems
 Small commercial hydronic heating and cooling circuits
 Protection of pumps, valves and heat exchangers from particulate contamination

How to use
Install the dirt separator in the system piping where it can intercept return flow or at another point where debris is likely to accumulate, following the system designer's instructions and local plumbing codes. Ensure proper alignment of the inlet and outlet and secure the connection to the 3/4" pipework. Periodically isolate the separator and open the drain or cleaning port to remove accumulated sediment; perform visual checks and maintenance according to the system's maintenance schedule to maintain performance.
Usage recommendations
Flush the circuit before installation to reduce initial particulate load, and establish a regular inspection and cleaning interval based on system usage and water quality.
