TPR350-04 Rotating Nozzle | 5075 PSI Turbo Cleaner

TPR350-04 Rotating Nozzle | 5075 PSI Turbo Cleaner

The Annovi Reverberi TPR350-04 Rotary Turbo Nozzle is a high-pressure rotating jet nozzle
built for professional contractors, industrial maintenance crews, and municipal cleaning teams who demand
maximum cutting power and efficient coverage. Featuring a 4.0 nozzle size, a rugged
1/4″ female inlet, and a maximum working pressure of 5,075 PSI, this
turbo nozzle converts pump output into a high-speed rotating zero-degree jet. The result is an aggressive
rotary cone pattern that chews through heavy contamination on concrete, masonry, and steel surfaces far
faster than standard fan tips or fixed 0° nozzles.

As part of AR’s TPR350 high-pressure rotary series, the TPR350-04 is engineered with a
durable brass body, ceramic orifice, and precision-balanced rotor assembly
designed for long service life under continuous-duty use. Rated for water temperatures up to
212°F (100°C), it integrates seamlessly with hot-water pressure washers used in
degreasing, sanitation, and heavy industrial cleanup. For operators working on large slabs, equipment yards,
and heavily stained hardscape, the TPR350-04 delivers the ideal blend of high impact and productive cleaning
width.

Performance & Design Highlights

• 4.0 orifice for strong impact and throughput: Larger than 3.0–3.5 nozzles, the 4.0 size
  allows more water volume while still concentrating pressure into a tight rotating stream—ideal for operators
  who want both serious cutting power and faster coverage on big jobs.
• High-pressure 5,075 PSI rating: Built to run with professional high-pressure pumps used in
  industrial wash bays, equipment yards, and contractor rigs where deep cleaning performance is non-negotiable.
• Rotating zero-degree jet: Concentrates water into a pinpoint jet and spins it at high RPM,
  multiplying the impact energy delivered to the surface compared with a conventional fan tip.
• 20° rotary cone pattern: The rotating action sweeps this cutting jet in a tight cone,
  effectively “scrubbing” the surface and reducing striping while still delivering deep penetration into
  textured, porous, or heavily contaminated materials.
• Hot-water ready: With a 212°F temperature rating and ceramic orifice, the TPR350-04 is
  an excellent match for hot-water machines used in degreasing, food and equipment plant washdown, and
  heavy-duty sanitation work.
• Engineered for daily use: The brass body, ceramic tip, and robust rotor assembly are
  designed to withstand vibration, pressure cycling, and long operating hours in commercial environments.

Typical Applications

• Concrete and flatwork restoration: Cleans parking lots, fueling pads, loading docks,
  sidewalks, steps, warehouse floors, and drive lanes where tire marks, oil stains, and embedded dirt require
  aggressive removal.
• Surface preparation: Preps concrete and metal surfaces prior to sealing, coating, or
  painting by breaking down heavy residues, chalky coatings, and weathered films so follow-up processes are
  more effective.
• Fleet and heavy equipment washing: Removes compacted mud, clay, grease, road film, and
  industrial residues from trucks, trailers, excavators, loaders, agricultural machinery, and other heavy
  equipment.
• Industrial & municipal maintenance: Ideal for wash bays, plants, treatment facilities,
  public works yards, and transfer stations where recurrent contamination and spills must be knocked down
  quickly.
• Hardscape & exterior cleaning: Restores retaining walls, block buildings, stadium steps,
  decorative concrete, and other masonry or stone surfaces affected by mildew, soot, atmospheric deposits, and
  urban grime.

Sizing & Compatibility Recommendations

• The 4.0 orifice is best paired with professional high-pressure washers that supply ample
  GPM at working pressure. Always confirm your machine’s GPM and PSI against nozzle sizing
  charts to ensure proper pump loading and rotor performance.
• Do not exceed the 5,075 PSI maximum pressure or the 212°F temperature
  rating to avoid damaging the nozzle or the pressure washer system.
• The 1/4″ female inlet threads directly to most commercial spray wands and guns and can
  be quickly adapted using standard quick-coupler fittings common on contractor and industrial rigs.
• Because of its concentrated rotary impact, the TPR350-04 is not recommended for delicate materials
  such as soft wood, thin siding, lightweight plastics, or freshly coated surfaces—always test on a small,
  inconspicuous area first.
• For optimal performance, pair this nozzle with clean, filtered water and a well-maintained pump system to
  minimize cavitation, abrasive wear, and internal stress on rotor components.

Maintenance & Best Practices

• Flush before use: Purge hoses, filters, and supply lines before installing the TPR350-04 to
  keep grit, sand, and debris out of the ceramic orifice and rotor assembly.
• Start on a durable surface: Bring the rotor up to speed with the spray aimed at a
  high-strength surface such as concrete, then move toward the work area once the pattern has stabilized.
• Control your distance: Adjust standoff distance until you achieve aggressive cleaning
  without gouging concrete, damaging joints, or stripping sound coatings—closer for maximum cutting, further
  back for more gentle action.
• Inspect regularly: Watch for changes in sound, rotation speed, spray uniformity, or visible
  leaks. These signs indicate internal wear or damage and mean the nozzle should be serviced or replaced.
• Plan for uptime: High-usage contractors and facilities should keep a spare TPR350-04 or a
  compatible repair kit on hand to minimize downtime and keep fleets and facilities on schedule.
