TPR255-08 Rotating Nozzle | 3700 PSI Turbo Cleaner

TPR255-08 Rotating Nozzle | 3700 PSI Turbo Cleaner

The Annovi Reverberi TPR255-08 Rotary Turbo Nozzle is a heavy-duty, high-flow turbo nozzle
built for the toughest commercial and industrial cleaning jobs. Featuring a large 8.0 nozzle
size, a standard 1/4″ F inlet, and a working pressure rating up to
3,700 PSI, this nozzle channels high volumes of water into a concentrated rotating jet that
tears through stubborn contamination on concrete, steel, masonry, and heavy equipment. When you need big
cleaning output from a high-GPM pressure washer, the TPR255-08 delivers the impact and coverage to match.

Built on AR’s proven TPR255-series rotary nozzle platform, the TPR255-08 uses a rugged brass
housing and wear-resistant internal rotor system designed for continuous-duty use in demanding environments.
It is rated for water temperatures up to 212°F (100°C), making it a perfect
match for hot-water pressure washers used in degreasing, sanitation, and industrial cleanup. For contractors,
municipalities, and facility maintenance teams looking to cover more square footage in less time while still
cutting deep into grime, this high-flow 8.0-size turbo nozzle is a powerful upgrade.

Key Specifications

• Model: TPR255-08 Rotary Turbo Nozzle
• Nozzle Size (Orifice): 8.0 (high-flow orifice)
• Maximum Pressure: 3,700 PSI (255 bar)
• Maximum Temperature: 212°F (100°C), hot-water compatible
• Spray Pattern: Rotating zero-degree jet forming an approx. 20° cone
• Inlet Connection: 1/4″ female (1/4″ F) – fits most pro guns and wands
• Body Material: Brass construction with hardened, wear-resistant internals
• Application Class: Commercial / industrial heavy-duty, large-area cleaning

Performance & Design Highlights

• High-flow rotary cleaning power: The large 8.0 orifice is tuned for
  high-GPM pressure washers, allowing more water volume to drive the rotor. That extra flow translates into a
  wide, aggressive rotating jet that covers more ground on every pass.
• Zero-degree impact with cone coverage: Pump output is compressed into a pinpoint
  zero-degree stream and then spun at high speed, delivering deep penetration into porous concrete, textured
  masonry, and rough steel — with the coverage of a cone spray.
• Faster cleaning on big jobs: The spinning cone pattern “scrubs” a circular path into the
  surface, breaking up heavy deposits and reducing the number of passes required on large slabs, bays, pads,
  and yards.
• Hot-water ready: A 212°F rating allows the TPR255-08 to be paired with
  hot-water units for rapid removal of grease, oil, and baked-on residues, especially in industrial and food
  or equipment processing environments.
• Proven TPR255 durability: The all-brass body, robust rotor assembly, and premium seals are
  engineered for daily use in wash bays, industrial facilities, agricultural operations, and contractor rigs.

Typical Applications

• Large concrete and flatwork cleaning: Ideal for wide parking lots, loading docks, truck
  courts, fueling pads, warehouse floors, and equipment yards where tire marks, oil stains, and embedded dirt
  must be removed quickly.
• Fleet and heavy equipment washdown: Designed for tractor-trailers, dump trucks, refuse
  vehicles, construction machinery, and agricultural equipment with layers of mud, clay, grease, and road
  film caked onto frames, undercarriages, and axles.
• Industrial and municipal facility maintenance: A powerful choice for wash bays, transfer
  stations, maintenance yards, treatment plants, and processing areas where sludge, slurry, and industrial
  residues accumulate.
• Concrete and masonry restoration: Cleans retaining walls, block buildings, precast
  structures, stadium steps, and hardscape surfaces, removing mildew, soot, atmospheric buildup, and
  weathered contaminants.
• Pre-treatment and surface preparation: Helps break down heavy deposits, chalky coatings,
  and deteriorated sealers on concrete or metal before chemical treatment, mechanical prep, or recoating.

Sizing & Compatibility Recommendations

• The 8.0 orifice size should be matched with higher-GPM commercial or industrial pressure
  washers. Small residential or low-flow electric units typically do not provide sufficient water volume to
  spin the rotor effectively.
• Verify your machine’s GPM and PSI ratings against nozzle sizing guidelines to ensure
  proper pump loading and strong, consistent rotor speed. Correct sizing maximizes cleaning performance and
  helps extend component life.
• The 1/4″ F inlet threads directly onto most professional spray guns and wands and is
  easily adapted via standard quick-coupler fittings used in commercial wash setups.
• Do not exceed the rated 3,700 PSI or 212°F; confirm that hoses, guns,
  lances, and fittings in the system share equal or higher ratings for safe operation.
• Because of its aggressive impact and high flow, the TPR255-08 is not recommended for delicate materials
  such as soft wood, thin siding, lightweight plastics, or freshly coated surfaces—always test in an
  inconspicuous area and adjust standoff distance as needed.

Maintenance & Best Practices

• Protect the internals: Always flush your pressure washer lines and filters before
  installing the nozzle. Grit, sand, or debris can damage the orifice and rotor assembly, leading to loss of
  rotation and premature wear.
• Spin up safely: When starting, aim the jet at a durable surface (like concrete or a wash
  pad) to allow the rotor to come up to speed smoothly before moving closer to the work surface.
• Control your distance: Adjust standoff distance until you achieve aggressive cleaning
  without gouging concrete, blowing out joints, or damaging coatings. On softer materials, back off and let
  the rotary action do the work.
• Inspect often: Monitor for changes in the sound of the rotor, uneven spray patterns,
  visible leaks, or external damage—these are signs that service or replacement is needed to maintain safe,
  consistent performance.
• Plan for uptime: For crews using turbo nozzles daily, keeping a spare TPR255-08 or a
  compatible repair kit on hand minimizes downtime and ensures you always have full cleaning power ready for
  the next job.
