Push button design - high quality, robust and durable, one-hand operable, fully automatic quick release coupling in safety design with high flow rates - venting is achieved by pressing the push button twice - on the first press, the coupling is vented, yet the plug remains secured in the coupling - after the second press, the plug is released - thus preventing the notorious "whiplash effect" and the risk of injury to the operator.The first time the push-button is pressed, the coupling is vented, yet the plug remains secured in the coupling - after the second press, the plug is released - this prevents the notorious "whiplash effect" and practically eliminates the risk of injury to the operating personnel - the safety version complies with the ISO standard DIN EN ISO 4414 Further technical features: - Flow rate (air): 1800 (at 6 bar, mounted plug and Δp = 1 bar)l/min

zero.
