How can we help you?

For your convenience, we provide a short manual for machines S4.0/7.5/11.0/15.0/18.5/30.0 (HP).

These dust suppression machines generate a consistent stream of microdroplets to capture airborne dust particles and prevent the escape of fugitive dust.

This manual does not replace the official manual.

With a proper maintenance the machine will operate smoothly for many seasons.

  • Fan and barrel: Check the inside of the barrel for damage. Any damage to the barrel can cause a reduction in efficiency. Repair the damage using a quality fiberglass plastic and strive for a smooth surface. Check the fan for damage.
  • Bearings: It is important that the bearings are lubricated before each operating season, or after
    every 250 operating hours (can be less according to the environment).
  • Pump: see manual pump
  • Water manifold and nozzle ring assembly: Before starting/using the machine, please check that all water nozzles in the nozzle ring have the proper spray pattern. If the spray pattern of an individual nozzle deviates; clean or replace the nozzle.
  • Water hoses: Check the camlock and other water couplers for damage and make sure that the gaskets are in place and intact. Check the status from the hoses on leakages.
  • Clutch: The cannon can be turned manually. If this maneuver is too hard to execute, the nut needs to be unscrewed half a turn or more.
  • Water filter: When there is dust visible, clean the filter. In order to do so, shut down the pump and stop the water supply. Unscrew the glass bulb and remove the filter cartridge to clean the inside.
  • Legionella: If the risk exists that contaminated water is used, clean and disinfect the water circuit. Follow the local regulations and laws concerning legionella disease.
  • Electrical cabinet: We recommend a regular check of the electrical cabinet by a certified electrician
  • Power cable: Check that the power cable is in a good state without damages.
  • Electrical connections: It is important to control and check all electrical connections and cables at the beginning of each season.
  • Frost protection: Store the machine in a frost free and dry area to prevent the machine from freezing. If there might be a freezing risk, remove all the water from the system. Purge the filter, remove the hose from the filter and blow compressed air (<5 bar) through the system.
