TPR255-045 Rotating Nozzle | 3700 PSI Turbo Cleaner

TPR255-045 Rotating Nozzle | 3700 PSI Turbo Cleaner

The Annovi Reverberi TPR255-045 Rotary Nozzle is a high-performance turbo nozzle designed
for contractors and facilities that need more impact, more coverage, and less time on the wand. Rated for up
to 3,700 PSI with a standard 1/4″ F inlet, this rotary head combines a
concentrated zero-degree jet with a fast-spinning cone pattern to deliver aggressive cleaning action on
concrete, masonry, metal, and heavy equipment. The 4.5 nozzle size is tuned for higher-flow
commercial and industrial pressure washers, giving you the flow volume and impact required to power through
demanding jobs.

Built on AR’s proven TPR255 platform, the TPR255-045 features a durable brass body and
wear-resistant internal components designed to hold up under continuous-duty use. A 20° spray
angle provides a focused yet productive cleaning footprint, while the vertical start
design helps stabilize the spray pattern and reduce kick when the trigger is first pulled. With a
212°F (100°C) maximum temperature rating, this turbo nozzle can be paired with many
hot-water units, making it a versatile upgrade for professional wash operations.

How the TPR255-045 Turbo Nozzle Works

• A precision 4.5-size orifice focuses pump output into a high-velocity jet, which drives an
  internal rotor to spin at very high speed. This converts a single zero-degree stream into a rotating cone of
  impact energy.
• The 20° cone pattern balances cutting power and coverage: narrow enough to dig deep into
  stubborn contamination, wide enough to cover ground efficiently on large slabs, pads, and walls.
• The vertical start behavior helps the rotor come up to speed smoothly when the trigger is
  pulled, reducing sudden torque on the gun and helping operators stay in control.
• By concentrating energy into a fast-spinning pinpoint, the TPR255-045 can strip grime, scale, and
  buildup significantly faster than a standard 15° or 25° fan tip at the same pressure.
• Correctly matching the orifice to the machine’s GPM and PSI keeps rotor RPM in the ideal
  range, preventing stalling and ensuring consistent, high-impact cleaning performance.

Typical Applications TPR255-045

• Concrete and flatwork cleaning: Driveways, fueling pads, parking lots, loading docks, ramps,
  and walkways where tire marks, oil stains, algae, and embedded dirt are difficult to remove with standard
  fan tips.
• Fleet and heavy equipment washing: Trucks, trailers, loaders, excavators, farm machinery, and
  construction equipment with baked-on mud, clay, road film, and grease packed into corners, undercarriages,
  and wheel assemblies.
• Industrial and commercial facilities: Warehouse and factory floors, service bays, wash pads,
  and production areas needing periodic deep cleaning to remove slurry, buildup, and tracked-in debris.
• Building exteriors and hardscape: Brick, block, stone, and precast surfaces; retaining walls;
  curbs; and decorative concrete where mildew, soot, and atmospheric buildup need aggressive removal.
• Surface preparation: Prepping concrete or metal before sealing, coating, or painting by
  breaking loose chalky residue, failing coatings, and heavy contamination so follow-up steps work more
  effectively.

Sizing & Compatibility Recommendations

• The 4.5 orifice size is best suited for higher-flow commercial and industrial pressure
  washers. Smaller residential units may not deliver enough GPM to spin the rotor consistently.
• Always verify your machine’s GPM and PSI before selecting the nozzle size to avoid
  overloading the pump or under-driving the rotor.
• The 1/4″ F inlet connects easily to most professional spray guns and lances using
  standard 1/4″ male threads or quick-coupler adapters.
• For hot-water applications, ensure the washer’s output temperature does not exceed
  212°F (100°C) and that hoses, guns, and other accessories are rated to the same or
  higher limits.
• Not recommended for delicate materials such as soft wood, certain siding, plastics, or recently coated
  surfaces—always test in an inconspicuous area and increase distance if needed to prevent damage.

Maintenance & Best Practices

• Flush the system before installing the nozzle to remove grit or debris that could damage the
  orifice or rotor asse
