6 ProSpray 3.25GBGeneral view of application Description of unit2. General view of application2.1 Application2.2 Coating materialsProcessible coating materialsi Pay attention to the Airless quality of the coatingmaterials to be processed.Dilutable lacquers and paints or those containing solvents, two-component coating materials, dispersions, latex paints.No other materials should be used for spraying withoutWAGNER’s approval.FilteringDespite suction filter and insertion filter in the spray gun, filteringof the coating material is generally advisable.Stir coating material before commencement of work.i Attention: Make sure, when stirring up withmotor-driven agitators that no air bubbles arestirred in. Air bubbles disturb when spraying andcan, in fact, lead to interruption of operation.ViscosityWith this unit it is possible to process highly viscous coatingmaterials of up to around 25.000 MPa·s.If highly viscous coating materials cannot be taken in by suction,they must be diluted in accordance with the manufacturer’sinstructions.Two-component coating materialThe appropriate processing time must be adhered to exactly.Within this time rinse through and clean the unit meticulously withthe appropriate cleaning materials.Coating materials with sharp-edged additional materialsThese have a strong wear and tear effect on valves, high-pressure hose, spray gun and tip. The durability of these partscane be reduced appreciably through this.3. Description of unit3.1 Airless processThe main areas of application are thick layers of highly viscouscoating material for large areas and a high consumption ofmaterial.A piston pump takes in the coating material by suction andconveys it to the tip. Pressed through the tip at a pressure ofup to a maximum of 221 bar (22.1 MPa), the coating materialis atomised. This high pressure has the effect of micro fineatomisation of the coating material.As no air is used in this process, it is described as an AIRLESSprocess.This method of spraying has the advantages of finestatomisation, cloudless operation and a smooth, bubble-freesurface. As well as these, the advantages of the speed of workand convenience must be mentioned.3.2 Functioning of the unitIn the following there is a short description of the technicalconstruction for better understanding of the function.WAGNER ProSpray units are electrically driven high-pressurespraying units.A gear unit transfers the driving force to a crankshaft. Thecrankshaft moves the pistons of the material feed pump up anddown.The inlet valve is opened automatically by the upwardsmovement of the piston. The outlet valve is opened when thepiston moves downward.The coating material flows under high pressure through the high-pressure hose to the spray gun. When the coating material exitsfrom the tip it atomizes.The pressure regulator controls the volume and the operatingpressure of the coating material.Materials Object SizeModelPS 3.21PS 3.23PS 3.25PS 3.29PS 3.31PS 3.34PS 3.39Release agents, oils, undercoats, primers, fillers,synthetic resin-based paints, acrylic paintsrecommended nozzle size: FineFinish 0.008“ - 0.014“up to 200 m 2200 m 2 - 800 m2more than 800 m 2Emulsion paints, latex paintsrecommended nozzle size: 0.017“ - 0.027“up to 200 m 2200 m 2 - 800 m2more than 800 m 2Anti-corrosive agents, flame retardants, fabricadhesiverecommended nozzle size: 0.021“ - 0.031“up to 200 m 2200 m 2 - 800 m2more than 800 m 2Airless-scrapersrecommended nozzle size: 0.027“ - 0.039“up to 200 m 2200 m 2 - 800 m2more than 800 m 2= Recommended = Not-recommendedUncontrolled Copy
