The ASTURO K1/A Legend art. 00260 low pressure automatic spray gun is a professional spraying component designed for integration into automatic systems, robotic equipment and industrial painting lines. Unlike a manual spray gun, this component is controlled by the machine cycle or process automation, allowing spray opening and closing to be repeatable, controlled and suitable for continuous production. It is a suitable solution for companies that need application uniformity, consistent results and reduced variability caused by manual operation.

The product is intended for heavy and continuous-duty use in the paper, packaging, industrial finishing, component coating, woodworking, plastic and ferrous material sectors. It can be used to apply paints, fillers, primers, single-component enamels, liquid metallic shades, double-layer finishes, pastel shades, heavy enamels, two-component products, water-based coatings, glues and low-viscosity adhesives, always checking chemical compatibility, viscosity, feeding pressure and system configuration.

The main characteristic of the ASTURO K1/A Legend spray gun is its ability to work at low pressure with high spray regularity, making it suitable for processes where material deposition on the surface must be controlled. Low pressure helps improve spray fan management and reduce dispersion and waste, especially when the gun is installed on automatic lines where distance, travel speed, opening times and orientation are defined by the production cycle.

The Teflon product packings are particularly important because they are in contact with the coating material and help seal the circuit in applications with liquid products, paints, glues or compatible technical materials. Leather air packings support the pneumatic circuit, while stainless steel springs improve corrosion resistance and long-term reliability of the control unit. These features make the spray gun suitable for professional use where service continuity, repeatability and scheduled maintenance are essential.

Feeding can be carried out at low pressure using a K24 double diaphragm pump or a pressure tank, depending on the material used, required flow rate and system layout. The double diaphragm pump is suitable when continuous material feeding is required, while the pressure tank is useful for applications that require flow stability and controlled material delivery. In both cases, product pressure, air pressure, flow rate and spray fan must be correctly adjusted before starting the production cycle.

From an operational point of view, the automatic spray gun must be mounted on rigid and adjustable supports, so that distance, angle and position remain constant in relation to the surface. Any variation in distance or inclination can change material distribution, causing build-up, lighter areas, irregular edges or coating thickness differences. During installation, it is therefore advisable to carry out spray tests on samples, check fan width, verify pass overlap and synchronize gun opening with workpiece or robot movement.

The application precision of the product is not measuring precision with numerical resolution, because the spray gun does not detect dimensions, heights, transmission play or geometric errors. Its precision is linked to the ability to repeat the spraying cycle consistently, maintaining opening, closing, flow rate, pressure, spray fan shape and material deposit unchanged. In an automatic system, this repeatability is essential to achieve homogeneous surfaces, reduce rejects, improve quality control and keep the process stable over time.

For correct use, the product should be filtered before entering the spray gun, material viscosity must be checked, nozzle cleanliness must be verified, and compressed-air quality must be controlled to prevent condensation, oil or impurities in the pneumatic line. Contaminated air or unfiltered material can compromise spray fan quality, cause clogging, surface defects, intermittent spraying or premature wear of internal components. Adjustment should be carried out progressively, starting from moderate values and increasing only as much as necessary to obtain a stable, uniform spray fan consistent with the required finish.

After use, especially with two-component paints, glues or products that dry quickly, the product circuit, nozzle, needle and material passages must be cleaned thoroughly. Dried residues can compromise closing, alter flow, cause dripping or change spray fan shape in later operations. In industrial environments, periodic checks of packings, springs, fittings, pneumatic control and nozzle seat are recommended, in order to maintain constant spray gun performance and reduce unplanned system downtime.

The ASTURO K1/A Legend art. 00260 low pressure automatic spray gun is therefore a technical solution for companies and system integrators requiring a reliable component for automatic, repetitive and professional painting processes. Its compatibility with different materials, structure suitable for continuous cycles, dedicated packings and feeding options through pump or pressure tank make it suitable for production lines where surface quality, process control and operational continuity are essential requirements.
