KS/QQ flat fan nozzle produces a flat spray pattern with a 50° or 60° deflection spray angle and offers the highest possible impact for a given feed pressure, up to 60% compared to standard turbulence flat fan nozzles. The innovative design ensures the ideal efficiency for deep cleaning and their quick connection makes them easy to assemble and avoids leakage. The different flow rates are identified by their colours available for proper selection. Materials are high quality PP and chemically bonded fibreglass to keep stability at high temperatures and be chemicals-resistant. These nozzles are widely used in surface pre-treatments.
