The ASTURO line filter for K15-K30 pumps, item 0301000, is a technical accessory designed to filter coating material inside professional spraying systems. Its function is to retain impurities, residues, solid particles, lumps or contamination present in the material before they reach the spray gun, nozzle or other sensitive components of the line. In a spraying system, the quality of the product flowing through the circuit is essential for maintaining regular flow, spray stability and good surface finish.

The image shows a robust cylindrical metal structure, suitable for integration into product lines connected to K15 and K30 pumps. The filter is designed to be installed in a functional position within the circuit, intercepting the material before delivery. In applications with paints, primers, fillers, enamels, protective coatings or sprayable materials, a line filter helps protect the system and reduce the risk of interruptions during work.

The line filter is particularly useful when using products that may contain mixing residues, particles that are not perfectly dispersed, impurities from the container or small agglomerates. These elements can cause nozzle clogging, spray fan instability, intermittent spraying, pressure loss, reduced flow rate or visible defects on the coated surface. Correct filtration therefore helps improve process continuity and reduce rework, material waste and downtime.

For this product, precision is not related to dimensional measurement or metrological resolution, but to the ability to keep the circuit cleaner and more controlled. Application precision also depends on flow stability and material regularity at the outlet: when the product reaches the nozzle uniformly and without significant impurities, the operator can obtain more consistent atomisation and a more homogeneous finish. Heights, transmission play and geometric errors are not measured directly by the filter, but line cleanliness can affect final quality and process repeatability.

The field of use includes body shops, workshops, finishing departments, industrial maintenance, the wood industry, applications on metal, plastic, automotive components, panels, structures and technical surfaces. The filter is suitable for operators using ASTURO K15 and K30 pumps who need to keep the coating circuit more efficient. In professional contexts, an adequate filtration system is an important support for protecting nozzles, fittings, spray guns and line components from contamination and abnormal wear.

Before installation, compatibility with the pump and system configuration should be checked, the condition of the fittings should be inspected, and the assembly should be verified to ensure there are no leaks or abnormal play. The filter should be installed according to the flow direction required by the system and should remain easily accessible for inspection and maintenance. Incorrect installation may reduce filtration efficiency, cause pressure drops or create critical points in the circuit.

During use, the filter should be checked periodically and cleaned or replaced according to operating conditions and the type of product used. Residues accumulated inside the filter can reduce material passage, cause flow drops and affect spraying continuity. Regular maintenance helps maintain stable flow, protect the pump and limit defects caused by contamination. The ASTURO line filter for K15-K30 is therefore an essential accessory for users of professional coating systems who need reliability, circuit cleanliness and consistent finish quality.
