TPR350-08 Rotating Nozzle | 5075 PSI Turbo Cleaner

TPR350-08 Rotating Nozzle | 5075 PSI Turbo Cleaner

The Annovi Reverberi TPR350-08 Rotary Turbo Nozzle is the top end of AR’s 350-series rotary
family, built for professionals who demand maximum impact, high flow, and rugged reliability on the toughest
jobs. Featuring a large 8.0 nozzle size, a robust 1/4″ female inlet, and
a maximum operating pressure of 5,075 PSI, this nozzle converts pump output into a
high-speed, rotating zero-degree jet. The result is an extremely aggressive rotary cone pattern that cuts
through hardened deposits, grease rings, scale, roots, and stubborn buildup on concrete, steel, masonry, and
inside sewer and drain lines far more effectively than standard fan tips.

Built on AR’s proven TPR350-08 high-pressure rotary platform, the TPR350-08 pairs a durable
brass body with a wear-resistant ceramic orifice and precision-balanced rotor
assembly designed for continuous-duty use. Rated for water temperatures up to 212°F (100°C),
it works seamlessly with hot-water pressure washers and jetters used in industrial degreasing, pipeline
maintenance, and heavy washdown work. For contractors, municipalities, and plant maintenance teams running
high-flow, high-pressure systems, this 8.0-size nozzle delivers maximum throughput, cutting performance, and
service life in the most demanding environments.

Performance & Design Highlights

• Maximum-flow 8.0 orifice: The largest nozzle in the 350-series, the 8.0 size is tuned for
  high-GPM professional pumps and jetters, moving substantial water volume while still compressing it into a
  tight, high-RPM rotating jet. This combination delivers exceptional stripping power and cleaning speed on
  large surfaces and in long pipe runs.
• 5075 PSI pressure capability: Engineered to run at serious pressure levels, the TPR350-08
  has the deep cutting energy needed for heavy, compacted, or hardened contamination in industrial, municipal,
  and sewer applications.
• Rotating zero-degree jet: Instead of a static 0° stream, the internal rotor spins the
  jet at high speed, multiplying impact and creating a chisel-like action that outperforms traditional fan
  tips in heavy soil conditions.
• 20° rotary cleaning cone: The spinning jet sweeps a compact cone pattern, providing
  consistent coverage and helping to reduce striping while still delivering deep penetration into tough
  surfaces and pipe walls.
• Hot-water ready design: With a 212°F rating and ceramic internals, the
  TPR350-08 is ideal for grease-heavy industrial environments, food and equipment plants, and sewer jobs where
  heated water dramatically improves cleaning performance.
• Continuous-duty construction: A brass housing, reinforced internal components, and a
  precision-balanced rotor are built to withstand vibration, pressure cycling, and extended operating cycles in
  daily professional use.

Typical Applications

• Sewer and drain line jetting: When installed on a compatible jetter hose and skid, the
  TPR350-08 is a go-to tool for cutting through grease rings, heavy scale, roots, and stubborn deposits in
  sewer laterals, branch lines, and main drains—ideal for municipal and commercial jetting contractors.
• Large-area concrete and flatwork cleaning: Excels on big parking lots, loading docks,
  fueling pads, warehouse floors, aprons, and industrial yards where tire marks, oil staining, and embedded
  grime require aggressive cutting action and high water volume.
• Industrial washdown: A powerful choice for manufacturing plants, processing facilities, and
  maintenance yards where slurry, scale, sludge, and heavy residues accumulate on floors, pits, and
  containment areas.
• Fleet and heavy equipment maintenance: Removes compacted mud, clay, grease, and road film
  from trucks, trailers, refuse vehicles, agricultural machinery, and construction equipment with fewer
  passes.
• Pre-treatment & surface prep: Breaks down thick contaminants, chalked coatings, and
  deteriorated sealers on concrete or steel before chemical cleaning, mechanical prep, or recoating, helping
  follow-up processes work more efficiently.

Sizing & Compatibility Recommendations

• The 8.0 orifice size is designed specifically for high-flow pressure washers and jetters.
  Always verify your machine’s GPM and PSI against nozzle sizing charts to ensure proper pump
  loading and strong rotor performance.
• Do not exceed the 5,075 PSI maximum pressure or 212°F temperature
  rating; staying within these limits protects both the nozzle and the system.
• The 1/4″ F inlet connects quickly to most commercial spray wands, jetter lines, and
  high-pressure fittings, and can be used with standard quick-connect couplers for fast changeover in the
  field.
• Because of its intense rotary cutting action and high flow, this nozzle is not suitable for delicate
  surfaces such as thin siding, soft wood, lightweight plastics, or freshly coated materials—always
  test in an inconspicuous area and adjust standoff distance as needed.
• For sewer/drain work, use hoses, couplings, swivels, and PPE rated for equal or greater pressure and
  temperature, and follow all relevant safety and operating guidelines.

Maintenance & Best Practices

• Flush before use: Purge lines and filters thoroughly before installation to keep sand,
  grit, and debris out of the ceramic orifice and rotor assembly, which can reduce rotation or cause
  premature wear.
• Stabilize before engagement: Start with the spray aimed at a durable surface (such as a
  wash pad or the interior of the pipe) so the rotor can reach full speed before moving closer to sensitive or
  critical surfaces.
• Adjust standoff distance: Move closer for maximum cutting power on tough industrial
  surfaces, and increase distance as needed to avoid unwanted etching or scarring on less robust materials.
• Monitor performance: Changes in sound, rotation speed, or spray uniformity often signal
  internal wear or blockage—inspect and service the nozzle promptly to maintain safe, consistent operation.
• Plan for uptime: For high-usage environments, keeping a spare TPR350-08 or compatible
  repair kit on hand helps minimize downtime and keeps cleaning and jetting operations on schedule.
