Installation Quality

Many businesses are experiencing less work and more down time during the COVID-19 pandemic, but instead of waiting around for the phones to ring, workshops should use this time to get a handle on all the maintenance tasks that are often put on hold. By taking on these tasks, the equipment will be ready for use when work starts to increase, and any maintenance issues found can be handled during this down time and not on the client’s time.

Keeping equipment in tip top condition is very important when extending its longevity. Dust collectors need maintenance to ensure that they are working as needed, for longer. The maintenance of the equipment is not only for the equipment, but also for the health of the employees on the workshop floor. Dust collectors that are not maintained correctly will not work correctly, and therefore will affect the quality of the air.

When maintaining your dust collector, the following checklist should be put in place:

  • Record your differential pressure to see if air filters need to be replaced. If differential pressure is monitored and recorded on a regular basis you will notice when a high differential is recorded, indicating the need for a filter change, or if the pressure suddenly drops, this may indicate a hole in the filter.
  • Inspect the drum to make sure that they are emptied before the dust reaches the top and blocks the hopper. This can damage the filters and can create a dangerous situation where the dust could ignite.
  • If damage occurs to the valves and hoses this can cause a loss of compressed air, and leakage. Inspecting the valves and hoses regularly and correctly, can limit any damage done to the equipment and time wastage.
  • Examine door seals and gaskets to make sure that the seal has not been damaged, which will result in the dust inside the collector to escape. Damaged seals and gaskets need to be replaced for the dust collector to work properly.
  • Confirm that compressed air settings are set as specified in the dust collector’s manual. Compressed air is used to clean the filters and if it is set too low the filters will not be cleaned, and if set to high, it will damage the filters.
  • Airlocks are required to isolate any fires that could occur within the dust collector. The airlock wipers inside of the airlock need to be replaced when worn out as this will reduce the airlock’s performance.
  • Consult your user manual with regards to which bearings need lubrication, and when. Fan bearings need to be lubricated to keep the dust collector working.
