Flow diameter 11 mm - 3750 l/min. Suitable for use with air tools with high flow requirements. Quick couplings with sleeve and body of steel, now surface treated with environment friendly chrome-6 free electric zinc plating, which has improved durability and additional corrosion protection. Low connection force required and low pressure resistance occurs when disconnecting. Couplings with recognised strong flow characteristics that give powerful compressed air tools and low pressure drops in the system. Temperature range: -20°C - +100°C. Air flow with inlet 6 bar at ∆p 0.5 bar. Max. working pressure 35 bar.
