- Ensure that air can flow unimpeded through the cyclone filter and dustbin to the vacuum cleaner. Prevent the air flow from being obstructed (for example by blocking the suction hose), creating a powerful vacuum in the dustbin.
- Avoid obstructing or restricting the air flow at all times. The air passage can for instance be obstructed or limited by a (partial) blockage of the vacuum hose and / or the nozzle. The air flow can also be limited when the dust port is too small and / or a nozzle that is too small. The advice is to run the vacuum cleaner at a lower speed for smaller dust ports / nozzles. If that is not possible, a nozzle with a variable air inlet can also be used. This allows air to be drawn in from the outside, reducing the underpressure in the dustbin. When used properly, all our dustbins will not dent.
- Do not vacuum dust that is very hot. Dust that is already in the dustbin can catch fire.
- Do not vacuum flammable substances and flammable fumes. Also prevent sucking up material that has soaked up flammable substances which can ignite a fire.
- Do not vacuum carcinogenic dust without an appropriate HEPA filter.
- Empty the dustbin reguraly and do not store flammable material in the dustbin. Leaving material behind in the dustbin will dry out and can catch on fire more easily.
Where dust is being sucked up, there is a chance that static electricity will be generated. This is caused by dust rubbing against the inside walls of, for example, a vacuum hose or filter thereby creating friction. This friction gives the dust a different electrical charge than the surface on which it rubs. The extent to which static electricity is built up highly dependents on the material that is being sucked up. For example, sucking up plastic chips generates more static electricity than, for example, your ordinary wood chips. From a safety point of view, it may sometimes be necessary to reduce or prevent the build-up of static electricity. For instance, when dust is sucked up that is highly flammable or when dust is being sucked up in rooms with combustible fumes.
The build-up of static electricity can easily be reduced by grounding those parts that can generate static elecricity:
- A dustbin made out of metal can easily be grounded.
- A metal cyclone filter can also easily be grounded.
- A static dissipative hose can be used to reduce static electricity.
For more information about static electricity and how it can be reduced, you can consult the following information:
- How to reduce static electricty (YouTube video)
- Specifications for static electricity (work protocol).
Whether you need to ground your cyclone filter system or not depends on your specific situation. If you want to be sure, we recommend that you ground your complete cyclone filter system.
