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.
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.
How often should the dust container be emptied?
Empty it before it becomes full, not after. An overfull container can block the flow and may let dust back into the filter. How often depends on how much dust you produce.
Wear respiratory protection and gloves, avoid shaking the contents into the air, bag the waste, and dispose of it in line with your risk assessment.
