TPR350-045 Rotating Nozzle | 5075 PSI Turbo Cleaner

TPR350-045 Rotating Nozzle | 5075 PSI Turbo Cleaner

The Annovi Reverberi TPR350-045 Rotary Turbo Nozzle is a high-pressure rotating jet nozzle
built for contractors and industrial users who need both serious cutting power and higher flow for big
cleaning jobs. Featuring a 4.5 nozzle size, a rugged 1/4″ female inlet,
and a maximum working pressure of 5,075 PSI, this turbo nozzle converts your pressure washer’s
output into a tight, high-speed rotating zero-degree jet. The result is an aggressive rotary cone pattern that
chews through heavy contamination on concrete, masonry, steel, and other durable surfaces far faster than
standard fan tips or fixed zero-degree nozzles.

Part of AR’s premium TPR350 high-pressure rotary series, the TPR350-045 is constructed with a
durable brass body, a ceramic orifice, and a precision-balanced rotor
assembly designed to withstand continuous-duty use in harsh environments. Rated for water temperatures up to
212°F (100°C), it integrates perfectly with hot-water pressure washers for degreasing,
sanitation, and industrial cleanup where heat accelerates results. For operators who want a high-flow, hard-hitting
rotary nozzle that can keep up with demanding schedules, the TPR350-045 delivers a powerful blend of impact,
coverage, and durability.

Performance & Design Highlights

• High-flow 4.5 orifice: Larger than 3.0–4.0 sizes, the 4.5 nozzle allows more water volume
  while still focusing the stream into a tight, rotating jet—ideal for larger machines where you want more
  coverage without sacrificing cutting power.
• High-pressure capability up to 5,075 PSI: Built to run on professional high-pressure pumps
  used in industrial wash bays, contractor rigs, equipment yards, and plant facilities where serious cleaning
  performance is a must.
• Rotating zero-degree jet: Concentrates the pump’s output into a pinpoint stream and spins it
  at high RPM, multiplying impact compared with a fixed zero-degree or standard fan nozzle, and dramatically
  speeding up removal of heavy soil loads.
• Efficient 20° rotary cone: The spinning jet sweeps a tight cone pattern that effectively
  “scrubs” the surface, reducing striping and helping produce a more uniform finish across broad areas of
  concrete and hardscape.
• Hot-water ready: With a 212°F rating and ceramic orifice, the TPR350-045 works
  seamlessly with hot-water units for degreasing, food and equipment plant cleaning, and washdown work where
  heat makes contaminants easier to remove.
• Engineered for daily professional use: A robust brass body, hardened internals, and a
  balanced rotor assembly are designed to handle vibration, pressure cycling, and extended operating hours in
  demanding environments.

Typical Applications

• Large concrete and flatwork cleaning: Ideal for parking lots, fueling pads, loading docks,
  drive lanes, and warehouse floors where tire marks, oil stains, and embedded grime need more muscle than a
  standard spray tip can provide.
• Surface preparation: Prepares concrete and steel for sealing, coating, or painting by
  breaking down tough residues, chalked coatings, and weathered films so chemical cleaners and follow-up
  processes can work more effectively.
• Fleet and heavy equipment washdown: Cuts through compacted mud, clay, grease, and road film
  on trucks, trailers, refuse vehicles, construction machinery, and agricultural equipment.
• Industrial & municipal maintenance: An excellent choice for wash bays, treatment facilities,
  plant floors, transfer stations, public works yards, and other areas where recurring heavy contamination and
  spills must be knocked down quickly.
• Hardscape and exterior cleaning: Restores retaining walls, block buildings, stadium steps,
  decorative concrete, and stone or masonry surfaces affected by mildew, soot, atmospheric deposits, and urban
  pollution.

Sizing & Compatibility Recommendations

• The 4.5 orifice size is best matched with professional high-pressure washers that deliver
  sufficient GPM at working pressure. Always verify your machine’s GPM and PSI against nozzle
  charts to ensure proper pump loading and optimal rotor speed.
• Do not exceed the 5,075 PSI maximum pressure or 212°F temperature
  rating; staying within these limits protects both the nozzle and the pressure washer system.
• The 1/4″ F inlet threads directly to most commercial spray wands and guns and adapts
  easily with standard quick-coupler fittings used in contractor and industrial wash setups.
• Because of its concentrated rotary impact and higher flow, the TPR350-045 is not recommended for
  delicate materials such as soft wood, thin siding, lightweight plastics, or freshly coated
  surfaces—always test in an inconspicuous area first.
• For best results, pair this nozzle with clean, filtered water and a well-maintained pump system to minimize
  cavitation, abrasive wear, and stress on internal rotor components.

Maintenance & Best Practices

• Flush before use: Purge hoses, filters, and supply lines before installing the TPR350-045
  to keep grit, sand, and debris out of the ceramic orifice and rotor assembly.
• Start on a durable target: Bring the rotor up to speed with the spray directed at a
  high-strength surface such as concrete or a wash pad, then move into the main work area once the pattern is
  stable.
• Adjust your standoff distance: Move closer for maximum cutting power on tough industrial
  surfaces; back off slightly where there is risk of etching, scarring, or damaging joints and coatings.
• Inspect frequently: Watch for changes in sound, rotation, spray uniformity, or visible
  leaks—all indicators that internal components may be wearing and require service or replacement.
• Plan for uptime: For high-usage operations, keeping a spare TPR350-045 or a compatible
  repair kit on hand minimizes downtime and ensures your crew always has full cleaning power ready to go.
