A42 R2 – SELF-PROPELLED ROTATING CLEANING HEAD
Code: 2289/A
Product detailed description
The A42 R2 is a self-propelled rotating cleaning head designed for cleaning open tanks, vats, and containers of various shapes and sizes. Capable of operating at pressures up to 160 bar and flow rates up to 60 l/min, it is engineered for high-efficiency internal surface washing in industrial environments.
Unlike electrically driven systems, the A42 R2 is powered entirely by water pressure and flow, making it a true water motor. As the liquid passes through the unit, it drives a turbine connected to a planetary gearbox, which translates hydraulic energy into a combined rotary and orbital motion of the spray nozzles. This enables the nozzles to perform a precise and reliable cleaning cycle.
With a spray coverage of approximately 250°, the A42 R2 is ideal for applications where full 360° coverage is not required, such as open-top tanks, vats, and IBCs with partial access.
Key Features:
-
Max. pressure: 160 bar
-
Max. flow rate: 60 l/min
-
Hydraulic drive – operates via water pressure, no external power needed
-
Turbine and planetary gear system for smooth and powerful rotation
-
Spray coverage: ~250°, ideal for open containers
-
Robust construction for demanding industrial cleaning tasks
Typical Applications:
-
Open-top tanks and mixing vats
-
Agricultural and food processing containers
-
Industrial cleaning of chemical or production vessels
-
Municipal and wastewater utility tanks
The A42 R2 cleaning head offers a powerful and maintenance-friendly solution for automated washing of open containers where full rotation isn’t necessary, delivering high-impact cleaning with optimized water usage and mechanical simplicity.

PA: valves and accessories for high-pressure cleaning
PA is an Italian manufacturer of components for pressure washers, vehicle washing and industrial cleaning equipment. Its portfolio covers pressure control, liquid delivery and operator accessories, helping equipment builders and service teams configure the complete cleaning circuit around the pump.
Product range and applications
PA products include unloader valves, spray guns, lances and other accessories used in high-pressure washing systems. The wider range also covers components for chemical application and specialised cleaning tasks. Applications extend from mobile pressure washers and car washes to cleaning installations in industrial environments.
Selection and system integration
Select each component according to the actual working pressure, water flow, temperature and connection type. An unloader valve must be compatible with the pump and circuit layout, while the gun, lance and nozzle need to work together at the intended operating point. Chemical compatibility and replacement-part identification are also essential for service work.
