Description
Professional 150 bar cleaning from a 230 V single-phase supply. The Power Jet 150 (PJ150.600) is a professional cold-water pressure washer from Prex Pro, the pressure-washer division of SIMMM Engineering. Designed and manufactured in Italy for demanding commercial cleaning, it combines a low-speed motor with an in-house AXA brass pump.
It combines adjustable 30–150 bar working pressure with a 600 L/h flow rate, giving you the control to move from lighter vehicle and equipment washing to more persistent workshop, yard and machinery cleaning.
Professional cleaning performance
- Adjustable pressure: Set the working pressure between 30 and 150 bar (up to 2,170 PSI) to suit the surface and level of dirt.
- High water flow: A 600 L/h output (10 L/min) helps rinse loosened dirt away efficiently.
- Trade-friendly power supply: The 3 hp motor operates from a 230 V single-phase, 50–60 Hz electrical supply.
- Low-speed operation: The 1,450 rpm motor is matched to the professional AXA pump for sustained cleaning work.
- Detergent control: A built-in 12 L tank and adjustable detergent delivery support cleaning and degreasing applications.
AXA brass pump and protective systems
At the centre of the Power Jet 150 is a self-priming AXA brass pump with ceramic-coated stainless-steel plungers, stainless-steel valves and double water seals. An integrated adjustable bypass regulates pressure, while the total-stop system and thermal switch help protect the machine during use.
A rubber-protected 63 mm pressure gauge keeps the operating pressure easy to monitor. Front-facing connections, large wheels, a rotomoulded chassis and a rear accessory holder make the washer practical to set up, move and store.
