Ship crews use medieval tools - chipping hammers, grinders, needleguns - to remove deck rust. Such tools drive rust and salt into your steel instead of removing it: Reason why corrosion returns after 2-4 months and your deck never improves.

Only grit blasting gives over 5 years repair life. Aquajet AJ-50X and AJ-150XL are small 50 or 150 lbs blasters on wheels, designed to eradicate deck rust with ease. Blasters powered by ship air pressure, little natural grit and very little fresh water.

Cutting Edge Technology

Minimal Resources Needed

Aquajet, powered by 7-8 bar ship air pressure only, requires NO electricity, consumes very little water and only 1-3 tons of grit a month.

Low Maintenance

Operating within design limits powered by low air pressure, Aquajet hardly suffers downtime. Minimal maintenance, no ongoing wear part replacement.

Compact & Flexible

Moves on wheels. Hose end bends as easy as a garden hose. Thus, nozzle reaches behind stiffeners, pipe supports and other hard-to-reach areas.


Aquajet uses natural grits which bring no harm to aquatic life and can be reused 3-4 times.

Cost Effective & Efficient

Aquajet operating cost is a fraction of powertooling or high-pressure hydrojet blasting. It removes corrosion professionally in no time. Optimal feathering surface prep gives longest repair life - well over 5 years. This makes it by far the most economical solution of all deck repair options.

Cost of manpower and paint over 5 years:
Aquajet wet abrasive spot blasting:

Fully compliant to US & EU sandblasting regulations. Uses extremely low air pressure = cannot cause harm. Aquajet’s water shield prevents airborne blast dust and explosion risk. Overall, Aquajet imposes extremely low accident risk. Blasting produces only a quarter used sand of conventional sandblasting, grit stays close around cleaning area. Basic PPE ensures full protection for operators.


Aquajet's watershield prevents blasting dust and explosion risk. 7 bar operational pressure equals tap water pressure. 7 bar is safe. Not comparable with HP equipment running at over 200 bar having caused serious injuries leading to amputations or even death.

Highest Standard

Despite low pressure, Aquajet achieves the highest surface preparation standard Sa 2.5 in roughness and cleanliness.

Two Aquajet models


  • 50lbs blaster
  • Powered by ship air pressure
  • Needs 100 cfm air flow at 7 bar air pressure.


  • 150lbs blaster
  • Powered by ship air pressure
  • Needs 200 cfm air flow at 7-8 bar air pressure.

Aquajet compared to other tools

A brief comparison of our Aquajet and with other tools available
Cleaning Method Typical failure pattern paint failure upon… Number of required repairs in 5 years or 60 months Side effects & issues
Chipping, grinding 3 to 4 months => 15 to 20 repairs in 5 years negative vetting & inspection, ship downgrading & rejection
Hydrojetting 8 to 24 months, subject to workmanship => 2.5 to 7.5 repairs in 5 years considerable accident risk, 10 t water/day, frequent breakdown
Aquajet Blasting 4 to 8 years => 0.625 to 1.25 repairs in 5 years training and crew supervision recommended

Pressure Tool Comparison

If you connect a conventional 300 lbs shipyard blast set to the ship air onboard, nothing happens since ship air pressure is insufficient.

With a 390 cfm compressor, the conventional 300 lbs blaster blows out 50 to 80 kgs copper slag or sand per m2. (copper slag damages aquatic environment, correct procedure is to collect and return to shore. Sand harms your workers' lungs)

If crew is blasting just 8 days per month:
A conventional blaster takes at least 60 kgs per m2, 40 m2/day => 2.4 tons grit a day at 40 m2/day => 19.2 tons per month (8 full blast days per month)
Aquajet needs: 15-30 kgs p. m2, garnet is used 2-4 times, 40 m2/day => 150 to 600 kgs garnet a day (=600/4 to 1200/2) => 1.2 - 4.8 tons per month (8 full blast days per month)
In comparison, a 500 bar hydrojet uses 10 tons fresh water per day => 10 tons fresh water per day => 80 tons per month . (8 blast days). Hydrojet breakdown far higher: hydrojets operate at design limits.

Advantages of AJ-150XL versus high pressure water jet

Low Air Pressure
Needs only 200 cfm air flow.
Low Operational Pressure
Aquajet operates at very low pressures of 7-8 bar. All its components and hoses operate below design limits therefore not easy breakable (pls note that a 500 - 1000 bar water pump operates at design limits, and extremely high pressure leads to frequent equipment failure and downtime: 50 % downtime is usual for hydrojets).
No Risk of Accident
High pressure is the reason for hydrojetting equipment being known to be highly dangerous. Water jets have caused numerous leg amputations!
No Need of Special Training
Hydrojet workers need special training, special safety gear and/or certificates to be allowed to work with 500 - 2000 bar.
Feathering of Paint in Rust Spots
This kind of "feathering" is of highest importance for lasting overpaint performance to avoid rust, water, salt crystals hidden under old paint protrusions.
Even 35,000 psi UHP cannot achieve feathering - it is impossible for water jetting.
Roughness Hydojetting cannot create the important "grip" or roughness profile of 20-30 microns needed for paint to adhere on steel and old paint. Garnet blasting creates this roughness even at a relatively low pressure.
Hard to Reach Areas
You can bend and direct Aquajet nozzles just as easy as a garden hose. Perfect for work under and between pipes/structures. Impossible for all hydrojets.
Low Water Consumption
Aquajet water consumption is about 5 times lower than hydrojetting Aquajet AJ-150XL needs 7-8 bar air pressure, 200 psi air volume capacity and 1-2 tons fresh water per day. A 500 bar water jet needs about 30 litres fresh water per minute, usually 8-10 tons in 10 hours.
Cost of Equipment
Aquajet's price is a fraction of the cost of a 500 or 2000 bar water jet (which goes from 15-30,000 to 70,000 USD).
