The two-component-spray gun S2-K is designed and constructed for application of two component materials f. I. 2-k lacquers or glues. Depending on used air cap on each nozzle it sprays in a round- or flat spray. Depending on viscosity of fluid, the application can be adjusted individually via nozzle dimension, needle stroke, atomizing air pressure and material pressure. Supply of control air and atomizing air is done via gun body. Both air pressure and material pressure. Supply of control air and atomizing air is done via gun body. Both air supplies are controlled by one trigger.
