Laboratory tests have shown that without dust extraction, dust in the air per kilogram of sanded material is over 200 grams per kilogram, and dust on surrounding surfaces is almost 800 grams per kilogram. These may not seem like large quantities but when they accumulate over a long period, they could potentially turn into both a fire and health hazard for the business.
To combat the dust particles is where dust-extraction comes into play because it helps safeguard employees’ health & safety, especially with the variety of materials that are being used in the production process. In addition by having a dust-free work environment, it ensures control of the sanding process and allows for multiple work phases to be undertaken in the same room, delivering efficiency both for the business and in terms of tool usage. The lack of dust also reduces the risk of ‘dust pills’ and clogging as the dust can no longer collect in lumps on the sanding discs to the same extent and there is no longer a danger that sanded dust will build up and create grooves on the sanding surface and fill up the disc reducing its sanding capacity. This means that an abrasive such as Abranet® maintains its aggressive properties over the entire surface much longer than traditional paper materials that have long wilted and faded, making sanding more even and efficient.
Here are some tips from Neil Newbrook, business sector manager wood, Mirka UK, that will help you achieve a dust-free work environment:
- Using a pad saver will protect the backing pad from wear. If P80 to P120 discs are used with a pad saver, we recommend the insertion of the grub screw.
- Ensure that the product is regularly serviced for optimum performance.
- Make sure the fleece bag in the mobile extraction unit is not full and does not have any rips or holes. If it does, replace it.
- Periodically remove and clean the motor filter. This can be done by placing it in a bag and gently knocking the dust out of the filter. Or better still, use another vacuum or extractor to clean the filter. Once it is clean, replace the filter in the machine.
- Make sure the seal between the tank and upper section of the extractor is clean and not damaged.
- Use the clean filter system on the machine every day. This will prolong the life of the system as well as create a dust-free working environment.
- Store the machine in a dry place protected from frost.
- Ensure that all tools are performing to an optimal level.
- Ensure that the product is regularly serviced for optimum performance.
