TPR255-055 Rotating Nozzle | 3700 PSI Turbo Cleaner

TPR255-055 Rotating Nozzle | 3700 PSI Turbo Cleaner

The Annovi Reverberi TPR255-055 Rotary Nozzle is a professional-grade turbo nozzle engineered
for demanding pressure-washing environments where both aggressive impact and efficient coverage are essential.
Designed for contractors, fleet operators, and facility maintenance teams, this rotating nozzle delivers
high-performance cleaning on large, heavily soiled surfaces. Rated for operation up to
3,700 PSI and equipped with a standard 1/4-inch female inlet, the TPR255-055
is built to integrate seamlessly into most commercial pressure washer setups.

At the heart of this model is a 5.5 orifice size, carefully selected to balance pressure
and water volume. This sizing allows higher flow compared to smaller turbo nozzles while still maintaining
the pressure needed to drive a powerful rotating zero-degree jet. The result is a fast-spinning spray pattern
that cuts deeply into grime, scale, grease, and compacted dirt. This balance of impact and coverage makes
the TPR255-055 especially effective when paired with higher-flow commercial and industrial pressure washers.

The nozzle is constructed with a durable brass body and wear-resistant internal components
designed to withstand repeated use in harsh conditions. These materials provide excellent resistance to
pressure fatigue, thermal stress, and abrasion from fine debris in the water stream. With a maximum
temperature rating of 212°F (100°C), the TPR255-055 is also compatible with many
hot-water pressure washing systems, allowing operators to break down oils, grease, and stubborn residues
more quickly than cold water alone.

How the TPR255-055 Turbo Nozzle Works

The TPR255-055 uses a precision-engineered internal rotor to transform pressurized water into a
high-impact rotating spray. Water exits the 5.5-size orifice as a concentrated
zero-degree jet. This focused stream drives the rotor at high speed, converting the jet into a
rapidly spinning 20-degree cone pattern.

• The rotating cone concentrates cleaning energy into a tight circular path, effectively
  scrubbing the surface rather than simply rinsing it.
• Compared to fixed 15-degree or 25-degree fan tips, the rotary action delivers significantly
  higher impact per pass.
• The consistent spinning motion helps reduce visible striping and uneven cleaning on flat surfaces.
• When matched correctly to the pressure washer’s flow rate and pressure, the rotor maintains
  optimal speed without stalling.
• The vertical-start design helps stabilize the spray pattern as the trigger is pulled,
  improving operator control and reducing sudden kickback.

This combination of high impact and controlled rotation allows operators to clean faster while
maintaining consistent results across large areas. The nozzle’s design is particularly effective
on surfaces where dirt and contaminants are embedded deeply into pores or textured finishes.

Performance Advantages of the 5.5 Orifice

The 5.5 orifice size is a versatile choice for professional users who require more flow
than smaller turbo nozzles but still want aggressive cutting power. This size allows sufficient
water volume to fully drive the internal rotor while maintaining strong surface impact.

• Higher flow improves debris removal by carrying loosened material away from the surface.
• Wider effective cleaning path reduces the number of passes needed on large jobs.
• Balanced pressure and flow help minimize operator fatigue during long cleaning sessions.
• Well suited for machines designed for commercial, municipal, and industrial use.

Typical Applications

The TPR255-055 is designed for use in demanding environments where standard spray tips are too slow
or ineffective. Its aggressive yet controlled spray pattern makes it suitable for a wide range of
heavy-duty cleaning tasks.

• Concrete and flatwork cleaning: Parking lots, truck courts, fueling pads,
  sidewalks, drive lanes, and loading docks with heavy oil staining or tire marks.
• Fleet and heavy equipment washing: Tractor-trailers, construction machinery,
  agricultural equipment, and municipal vehicles with caked-on mud and road film.
• Industrial and municipal facilities: Wash bays, transfer stations, plant floors,
  and material-handling areas exposed to slurry, scale, or industrial residue.
• Building exteriors and hardscape: Concrete walls, curbs, retaining walls,
  steps, and masonry surfaces requiring restorative cleaning.
• Surface preparation: Prepping concrete or steel before sealing, coating,
  or painting by removing heavy contamination and loose material.

Sizing and Compatibility Recommendations

Correct sizing is critical to turbo nozzle performance. The TPR255-055 is intended for
higher-flow commercial and industrial pressure washers. Machines with insufficient flow
may not spin the rotor consistently, resulting in reduced cleaning effectiveness.

• Verify your pressure washer’s PSI and GPM ratings before selecting this nozzle.
• Use nozzle sizing charts to ensure proper matching and avoid pump overload.
• The 1/4-inch female inlet connects directly to most professional spray guns and wands.
• Do not exceed the rated pressure or temperature limits, and ensure all system components
  are rated accordingly.
• Avoid use on delicate materials such as soft wood, thin siding, plastics, or fresh coatings
  without testing and increasing standoff distance.

Maintenance and Best Practices

Routine maintenance helps ensure long service life and consistent performance from the
TPR255-055 rotary nozzle. Because turbo nozzles rely on precision internals, clean water
and proper handling are essential.

• Flush hoses and lines before attaching the nozzle to remove sand or debris.
• Start spraying away from the target surface to allow the rotor to reach full speed.
• Maintain a safe and effective standoff distance to prevent surface damage.
• Inspect regularly for leaks, uneven spray patterns, or reduced rotation.
• Replace worn internals or the nozzle itself when performance declines.

When properly matched to the right pressure washer and maintained correctly, the
TPR255-055 Rotating Turbo Nozzle delivers powerful, efficient cleaning for
professional users. Its combination of durability, aggressive impact, and controlled
rotation makes it an excellent choice for high-production cleaning on large, heavily
soiled surfaces.
