The abrasive humidification benefits in free spray sandblasting are 5 at least:
- Dust collecting
By humidifying sand before spraying, one can halt dustiness produced by blast of air and stop whipped up dust produced by treatment of surfaces
- Higher safety for operators
Humidification allows to carry out sandblasting operations, avoiding contact with whipped up dust or harmful substances, protecting the operator and those who are in the workplace.
- Water waste reduction
Water Blast does not flood the area of intervention. It uses 2 litres per minute of water, only
compared to 80 litres of a common hydro cleaning machine!
- A greater impact force on surfaces
The humidified granules of sand sprayed by the gun increase their own specific weight, producing a greater impact force and a higher removal performance.
- A reduction in management costs
Humidification consumes less air, less water, less abrasive...but most of all it allows to use low cost dusty sands which remarkably reduce management costs.
Why air-hydro sandblasting is better than common hydro sandblasting?
There are several reasons. It is important to underline that hydro sandblasting takes advantage of the venturi principle: by simply using a common hydro cleaning machine, one can get a mixture of water and abrasive.
N.B. The system may be powered by connection to water supply system or by means of water tank.
