HPW-DUST HIGH PRESSURE SUPPRESSION SYSTEMS

HPW-DUST

HIGH PRESSURE DUST SUPPRESSION SYSTEMS

OPERATING INSTRUCTIONS

Dynaset HPW Dust high pressure suppression system is based on HPW-pump and is specially designed to 

prevent dust emissions at crushing, pulverizing, demolition or to any process of dusting materials. HPW dust high 

pressure suppression system can be used effectively applications like quarries, recycling and waste management, 

material handling etc. 

 

Dynaset wide HPW pump series produce needed water pressure and flow to different dust suppression application. 

High pressure water mist is spayed via dust suppression nozzles round the dust particles. The weight of the water 

bounded dust particles increases multiply that makes them fall down. Low water consumption is achieved by tiny 

water mist that do not irrigate machine and surroundings wet. Various applicable forms of high power jets are 

available, turbo jets or dousing umbrella for area suppression, falling debris etc. 

Dynaset HPW Dust high pressure Suppression system is easy to install to any machine and is fully controlled 

from cabin. 

The system has next benefits: 

 

- Extremely low water consumption, no need for large reservoir. 

 

- Microscopic water binds dust particles effectively.

 

- No mud forming on machinery surface. 

 

- Good visibility, clean and better breathing air. 

 

- Saves health care expenses.
