2. General view of application2.1 ApplicationAll painting jobs in the workshop and on the buildingsite, small dispersion work with the spray gun or inter-nally fed Airless roller.Examples of objects of sprayingDoors, door frames, balustrades, furniture, wooden clad-ding, fences radiators (heating) and steel parts, internalceilings and walls.2.2 Coating materialsProcessible coating materialsDilutable lacquers and paints or those containing sol-vents, two-component coating materials, dispersions, la-tex paints.No other materials should be used for spraying withoutWAGNER’s approval.FilteringIn spite of the suction filter, the insertion filter in the spraygun and the high-pressure filter, filtering of the coatingmaterial is to be recommended in general.Stir coating material before commencement of work.ViscosityWith this unit it is possible to process highly viscouscoating materials of up to around 25.000 mPa·s.If highly viscous coating materials cannot be taken in bysuction, they must be diluted in accordance with themanufacturer’s instructions.Two-component coating materialThe appropriate processing time must be adhered toexactly. Within this time rinse through and clean the unitmeticulously with the appropriate cleaning materials.Coating materials with sharp-edged additionalmaterialsThese have a strong wear and tear effect on valves,high-pressure hose, spray gun and tip. The durability ofthese parts cane be reduced appreciably through this.3. Description of unit3.1 Airless processThe main areas of application are thick layers of highlyviscous coating material for large areas and a high con-sumption of material.A piston pump takes in the coating material by suctionand conveys it to the tip. Pressed through the tip at apressure of up to a maximum of 230 bar (23 MPa), thecoating material is atomised. This high pressure has theeffect of micro fine atomisation of the coating material.As no air is used in this process, it is described as anAIRLESS process.This method of spraying has the advantages of finestatomisation, cloudless operation and a smooth, bubble-free surface. As well as these, the advantages of thespeed of work and convenience must be mentioned.3.2 Functioning of the unitIn the following there is a short description of the techni-cal construction for better understanding of the function.WAGNER ProSpray units are electrically driven high-pressure spraying units.A gear unit transfers the driving force to a crankshaft.The crankshaft moves the pistons of the material feedpump up and down.The inlet valve is opened automatically by the upwardsmovement of the piston. The outlet valve is openedwhen the piston moves downward.The coating material flows under high pressure throughthe high-pressure hose to the spray gun. When the coa-ting material exits from the tip it atomizes.The pressure regulator controls the volume and the ope-rating pressure of the coating material.30 ProSpray 23gGeneral view of application Description of unitUnit on low carriagePay attention to the Airless quality of thecoating materials to be processed.Attention: Make sure, when stirring up withmotor-driven agitators that no air bubblesare stirred in. Air bubbles disturb whenspraying and can, in fact, lead to interruptionof operation.ii
