The ASTURO ECOE/SL lightweight HVLP spray gun with gravity feed cup is a professional compressed-air spray gun designed for painting ferrous materials, wood, plastic and automotive bodywork. The upper gravity cup allows the coating material to flow smoothly towards the needle and nozzle assembly, making the spray gun practical for finishing, touch-up, maintenance and technical coating applications. It is suitable for operators who require spray fan control, uniform material deposition and high surface finish quality.

HVLP technology, High Volume Low Pressure, operates with a high volume of air at low pressure and provides high paint transfer efficiency compared with less optimized conventional systems. This means that a greater amount of coating material is deposited on the surface, with reduced dispersion and better overspray control. In professional applications, this is important both for finishing quality and for optimizing consumption of paint, enamel or coating material.

The forged and anodized aluminium body provides light weight, surface resistance and comfortable handling during continuous use. The compact structure allows greater control on shaped parts, small surfaces, bodywork components, panels, wooden elements, plastic parts and metal workpieces. The air inlet= 1/4" M allows connection to a compatible compressed-air line, while the stainless steel needle and nozzle support durability of the delivery assembly in contact with liquid paints and enamels.

The spray gun is suitable for liquid paints and enamels, water-based paints and pastel shades, always checking compatibility between the coating material and the spray gun configuration. Application quality depends on correct material preparation, paint filtration, viscosity, air pressure, spray fan adjustment, material flow and spraying distance. Paint that is not correctly diluted or filtered can cause irregularities, orange peel effect, build-up, surface contamination or difficulty in producing a regular spray fan.

The spray gun adjustments allow the operator to adapt spray behaviour to the application. Material flow adjustment controls the quantity of coating delivered, spray fan adjustment modifies the width and shape of the atomization, and air control helps optimize spray fineness. For a uniform result, it is advisable to test the spray pattern on a control surface before the final application, progressively adjusting air and material flow until a stable and regular spray fan is obtained.

During use, the spray gun should be kept at a constant distance from the surface and guided regularly in relation to the workpiece. Movement should be smooth, with parallel and controlled overlapping passes, avoiding long stops on the same point. Moving too slowly can cause build-up and runs, while moving too quickly can reduce coverage and create differences in shade or thickness. Application precision is not linked to measuring resolution, because the spray gun does not measure dimensions, heights, transmission play or geometric form errors; however, it directly affects the precision of coating deposition.

In professional environments, the ASTURO ECOE/SL can be used in bodyshops for finishing and touch-up work, in woodworking for coating wooden surfaces, in workshops for treating metal parts, in maintenance for aesthetic and protective restoration, and in light industrial applications where a uniform surface finish is required. The precise and uniform spray fan helps control material distribution, while the lightweight design reduces operator fatigue during repeated operations.

To maintain consistent spray quality, the spray gun must be carefully cleaned after each use. The cup, internal passages, needle, nozzle and air cap must be washed with a product compatible with the coating used. Dried residues can alter atomization, clog the nozzle, affect needle sealing and change the spray fan shape. It is also advisable to periodically check seal condition, component tightening, compressed-air line filter cleanliness and absence of condensation in the system, because air contaminated by water or oil can damage the finish.

The ASTURO ECOE/SL lightweight HVLP spray gun with gravity feed cup is therefore a suitable solution for professionals looking for a manageable, efficient tool for technical painting on different materials. The combination of HVLP technology, forged and anodized aluminium body, stainless steel needle and nozzle and spray fan adjustment helps operators work with greater control, improving finish uniformity and the visual quality of the applied coating.
