MDB-2F Spare Parts FAQs
Straight answers to the questions people ask most about spare parts for a two-filter cartridge extraction unit with a dust container.
Which parts of a cartridge extraction unit wear out?
Filter cartridges are the main consumable. Lid and cover seals, drain valves, clamps and knobs, relays and fuses, and the feet or trolley of the dust container also wear or get damaged in use.
A failing seal lets unfiltered air leak, and a worn electrical part may stop the unit starting or cause nuisance trips.
How do I know when to change the filter cartridges?
Falling suction at the extraction point, more fume or dust in the workshop, or an indicator showing high resistance across the filter are the signs. How often depends on how much and what kind of fume or dust the unit handles.
Follow the maker's guidance, and change the filters before they block completely, as a clogged filter strains the fan.
Should both filters be changed together?
It depends on the unit, so follow the manual for your own machine. In a unit with more than one filter, the air divides between them, and a filter that has been in use for a while resists the flow more than a new one. Mixing new and old filters can therefore load them unevenly.
Some makers advise changing filters as a set, while others allow them to be changed individually when each is monitored separately. Check the data plate, the manual and the filter condition indicator for your unit, and ask our team if the guidance is unclear.
What does the dust container lid seal do?
The lid seal makes the container airtight, so that the suction inside the unit is maintained and dust cannot escape when the container is full. A worn, hard or flattened seal lets in false air, which reduces performance, and may release dust.
Check the seal whenever you empty the container, and replace it if it is damaged or no longer seals evenly.
