Reduces engine speed to idle on Jetstream blasters with mechanical engines. 40,000 psi (2750 bar). 5 ft (1.5 m) control cable.
The Jetstream mechanical Hydro-Throttle enables the operator to reduce the engine to idle speed and relieve the system of high pressure when the gun trigger is released- saving water and fuel and reducing wear on the engine and pump. When the gun is again engaged, the Hydro-THrottle increases the engine speed until the pump again reaches the set operating pressure.
