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.
How do I identify the correct spare for my extraction unit?

Use the data plate on the unit for the model and serial number, then match the part against your manual or parts list. Dust containers, lids, seals, holders and cover plates differ between units and between sizes, so appearance alone can mislead.
If you are not sure, send photographs of the old part and the data plate to our team.
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.
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.
