The high-pressure operation of the appropriate device is switched on and off by an electrical switching contact. If the gun is not being actuated, the high-pressure hose is always depressurised so making work easier and increasing worker safety. The gun is fitted with trigger guard and trigger safety as well as a plastic hand grip and forged steel pressure housing as standard. Applications with hot water up to 100°C can be carried out at any time. The HP 3000S-E-EXI high-pressure gun is especially suitable as an accessory for WOMA units in the Advanced and Expert series.
