How to collect 100% dust in free spray sandblasting?
The customers - not only focused on the performance of work but also on operators' health and environmental protection - often ask us.
WATER BLAST is the answer: a multifunctional sandblaster based on the principle of operation on sand humidification
The abrasive humidification benefits in free spray sandblasting are 5 at least:
1. 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
2. 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.
3. Water waste reduction
Water Blast does not flood the area of intervention. It uses 2 litres per minute of water, only
compared to 200 litres of a common hydro cleaning machine !
4. 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.
5. 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.
To sum up, the main features are as follows:
gradual and constant reduction of dust quantity, up to total removal.
reduction of compressed air consumption (up to roughly 25%), proportional to the increase of water inserted in the air-abrasive mixture.
The system also allows:
automatic shut-off of water jet when the sandblaster is turned off
adjustment of water quantity by operators from the working area
constant water capacity of 2.5 litres/min. up to a maximum distance of 80 metres.
air-sandblasting kit
N.B. The system may be powered by connection to water supply system or by means of water tank.
