Air duct cleaning in Meierijstad

Meierijstad in figures: a production municipality with many villages

Meierijstad has 84,304 inhabitants on 18,400 hectares of land, 458 inhabitants per km2, and ranks 45th of the 342 municipalities (CBS 2024). CBS classifies the municipality as moderately urban, class 3.

Industry and agriculture together make up 26.2% of the establishments, and industry is almost as large as business services. Duct maintenance in the villages of Meierijstad is therefore closer to the shop floor than in a city of offices.

When does dust in an extraction duct become dangerous?

Fine organic dust such as flour, meal and sugar can explode. A TNO memo states that an explosion is only possible above 60 g/m3 of fine dust in the air. A normally operating room seldom reaches that concentration, but loosening a thick layer of dust inside a duct can create it locally. The same principle applies to woodworking; the literature on dust explosions points to extraction installations, spark detection and ATEX.

Why you do not use compressed air in bakeries and dusty production

The Belgian sector guide for bakers leaves no room for doubt: no compressed air, hand brushes or brooms; use an industrial vacuum cleaner with a HEPA filter. TNO gives the Dutch bakery sector the same message and adds that an M class filter will do, except in EX zones, where an ATEX 114 certified unit is needed. The Dutch health based recommendation for inhalable wheat flour dust is 0.2 mg/m3 over 8 hours; that is an advisory value, not a legal limit.

For the duct this means: clean with a rotating brush and capture the dust immediately with extraction. A compressed air nozzle is handy inside a duct, but in a room with fine flour dust only if the duct is fully sealed and under negative pressure. More about this sector can be read under extraction in the bakery.

Duct cleaning Meierijstad: sealing, negative pressure and filtration

The core of safe cleaning is that loosened dust can go nowhere except to the extraction unit. Every section being cleaned stays under negative pressure the whole time, and if the unit exhausts indoors, a HEPA filter with 99.97% at 0.3 µm is required. Danduct supplies inflatable duct plugs to close off a duct section and foam caps to seal valves and diffusers. Everything about this is under negative pressure HEPA extraction for businesses.

1. Determine the type of dust and check whether the room is an EX zone.
2. Close off the run with a balloon at one end.
3. Connect the extraction unit at the other end and build up negative pressure.
4. Seal all valves in the production area.
5. Clean with the brush towards the extraction, in short lengths where layers are thick.
6. Check with a camera and record the result.

Which brushing machine for production ducts in the villages?

For long extraction runs in production halls, the Danduct Clean DC4 fits, with a reach of up to 30 metres in ducts of 100 to 600 mm and brushes of 0.6 or 0.9 mm polypropylene. For short branches at a machine or in a canteen, the PD4 on a power drill is often enough. Ducts wider than 600 mm are outside the range of both; ask for advice in that case. You can compare duct cleaning kits explained to see all the options. For the broader industrial approach there is a page on factory ductwork cleaning.

Fictional example: a food producer with a flour silo and an office

A fictional food producer in one of the villages has a production room with flour dust, extraction above the mixers and an office with mechanical ventilation. The facilities team cleans the office ducts dry with a brush. The mixer extraction is tackled in sections, with a balloon at one end, a HEPA extraction unit at the other and all valves in the production room sealed. Compressed air is not used in the production room at all. Fictional example without a real client or measurements.

The lesson from this example is to treat the two systems in one building as two separate jobs. The office can follow a simple routine, while the production extraction gets its own preparation, its own checklist and its own record of what was found.
