The ASTURO ASP2001 ECO HVLP automatic spray gun, art. 00292, is a low-pressure automatic spraying unit designed for industrial applications on robotic systems, automatic painting equipment and production lines where controlled and repeatable coating distribution is required. HVLP technology, High Volume Low Pressure, uses a high air volume at low pressure, promoting better transfer efficiency compared with conventional systems and reducing material dispersion in the working area. This is particularly important in industrial applications where paint consumption, coating uniformity and spray-booth cleanliness directly affect final quality and process costs.

The product is suitable for use on robotic and automatic systems, especially for painting ferrous materials, wood and plastic. It can be used with fillers, primers, single-component enamels, liquid stains, double-layer metallic coatings, pastel shades, heavy enamels, component paints and water-based coatings. This versatility makes it suitable for industrial paint shops, automotive production, metal fabrication, painted mechanical component manufacturing, panels, profiles, metal parts, bodywork elements, technical supports and components requiring a uniform finish and controlled application process.

From a construction point of view, the ASP2001 ECO HVLP is a compact automatic spray gun designed for integration on brackets, robotic arms, pneumatic systems or dedicated equipment. The body weight is 900 g, which is useful when the gun must be mounted on automatic axes or devices where mass, size and stability influence movement accuracy. The compact design facilitates installation in restricted spaces and allows a cleaner arrangement of air and product connections inside spray booths or automatic systems.

The spray gun is operated by a three-way pneumatic system or solenoid valve. This configuration allows the opening and closing of the spraying cycle to be synchronized with the movement of the machine, robot or production line. In an automatic system, precision depends not only on the quality of the spray gun but also on correct pneumatic control, stable air pressure, distance from the workpiece, travel speed and repeatability of the spray position. For this reason, the product is especially suitable for processes where the cycle must remain constant, repeatable and controllable.

The atomizing air inlet is designed with a quick coupling for 6x8 tube, while the control air inlet uses a quick coupling for 4x6 tube. The product inlet is 1/4 G. This separation between atomizing air, control air and product feed allows more precise process management and enables the spray gun to be adjusted according to the coating material being applied. The stated operating air pressure is 3.5 bar, with a maximum air pressure of 7 bar and a maximum product pressure of 7 bar. The spray gun must be used within these values, avoiding overpressure that could alter the spray pattern, increase overspray, create unstable deposition or reduce the service life of internal components.

The available nozzle range includes diameters from Ø 0.7 mm to Ø 2.2 mm. Choosing the correct nozzle is technically essential, because it affects product flow rate, atomization fineness, spray pattern width, applied thickness and finish uniformity. Smaller nozzles are generally suitable for more fluid products and precision applications, while more viscous products, fillers, primers or heavier enamels normally require larger sections to ensure constant flow and correct feeding. An incorrect nozzle selection may cause spraying defects, uneven deposition, streaks, excessive material, orange peel, poor coverage or spray pattern instability.

HVLP technology is particularly useful when optimizing material transfer onto the surface to be coated. Low pressure reduces particle velocity and allows more controlled deposition with less material bounce-back from the workpiece. In industrial processes, this helps improve efficiency, reduce paint waste and limit contamination in the working area. However, the final result also depends on correct system adjustment: product viscosity, filtration, feed pressure, temperature, spraying distance, spray-gun orientation, pass overlap and travel speed must all be consistent with the application cycle.

The working temperature of both product and air must be between 15 °C and 50 °C. This is important because temperature affects viscosity, paint behaviour, atomization and film levelling. If the product is too cold, it may become more viscous and produce less fine atomization; if it is too hot, application performance or drying behaviour may change. In industrial departments and automatic spray booths, it is therefore advisable to maintain stable process conditions, control material preparation and ensure that both air and product are clean, filtered and free from contaminants.

The ASP2001 ECO HVLP is suitable for painting cycles requiring application precision, repeatability and spray-pattern geometry control. In an automatic process, the spray gun must always work at a constant distance from the workpiece and follow a consistent path, because changes in height, inclination or travel may generate thickness differences and finishing defects. Mechanical play in the support or robotic arm is also important: vibration, deflection, misalignment or non-repeatable movement can affect spray-pattern stability and material distribution. For this reason, the product is suitable for technicians and integrators who need to build reliable, adjustable automatic painting systems for repeat production.

In quality control, this spray gun helps standardize the application process and reduce variability from one part to another. Correct adjustment supports constant coverage, more uniform thickness, fewer surface defects and better repeatability of the final result. In automotive and precision mechanical applications, where surface finish is often part of both perceived and functional component quality, an automatic HVLP spray gun allows painting to be integrated into a controlled cycle, reducing manual intervention and improving process consistency.

For correct use, it is advisable to select the nozzle according to product viscosity and surface type, check air pressure before starting the cycle, inspect the cleanliness of internal passages, filter the coating material, maintain a constant distance from the workpiece and schedule regular maintenance of needle, nozzle, seals and ducts. Cleaning after use is essential, especially with primers, fillers, heavy enamels and water-based coatings, because dry residues or internal deposits can alter the spray pattern, reduce flow rate and compromise process repeatability.

The ASTURO ASP2001 ECO HVLP automatic spray gun, art. 00292, is therefore a professional solution for industrial painting systems requiring controlled application, good transfer efficiency, compatibility with different coating materials and integration into automated equipment. The combination of HVLP technology, low-pressure operation with diaphragm pump, pneumatic or solenoid-valve actuation, quick couplings, wide nozzle range and compact structure makes it suitable for technicians, maintenance specialists, integrators and production managers who need to optimize quality, repeatability and continuity in the painting process.
