Air duct cleaning in Lelystad

What kind of businesses does Lelystad have?

The sector breakdown according to CBS 2024, with percentages calculated on 10,670 establishments:

Manufacturing, trade and transport together account for 46.5% of establishments. That makes Lelystad a municipality where hall ventilation and industrial extraction play a large role, alongside a solid share of public buildings.

For a cleaning contractor or facilities team this mix matters: the same week can bring a dusty production hall and a classroom wing, each needing a different brush, a different level of sealing and a different report for the client.

Newly delivered does not automatically mean clean

A common assumption is that the ducts of a new building are clean. In the Frisse Scholen (Fresh Schools) process manual, RVO (Netherlands Enterprise Agency) reports that air ducts in newly delivered schools turn out to be contaminated with construction dust. That is a strong argument for a handover inspection, for commercial buildings too.

The revised EN 15780 from 2025 contains tables in Annex A for cleanliness classes, inspection intervals per class and acceptable levels, with a separate table for new ducts. For new buildings you determine the ventilation capacity under the Building Works Living Environment Decree (Bbl) with NEN 1087, and the requirements are in art. 4.122 onwards. For background, see NVRL quality mark for cleaning contractors.

• Ask for a camera inspection of the main runs at handover.
• Have construction dust removed before the installation goes into full operation.
• Record the baseline, so you can compare later.

A handover inspection is also a moment to check practical points: are there enough inspection hatches, are they reachable without removing fixed ceilings, and are their positions marked on the as built drawings? Fixing that at handover is far easier than years later.

School buildings and care in Lelystad: making fresh air measurable

For schools the requirements are concrete. Every classroom in primary, secondary and special education must have a CO2 monitor (Bbl art. 3.143). The Frisse Scholen programme has three ambition levels with CO2 limits.

You only achieve those values with an installation that is maintained both technically and hygienically. With decentralised ventilation, the installer must also visit every classroom for the filter change. More on the approach in education buildings can be found under Frisse Scholen ventilation.

Ventilation duct cleaning Lelystad: which brush for which duct?

The brush determines the result at least as much as the machine. Danduct Clean supplies soft, standard and more aggressive Tynex brushes from 100 to 600 mm, and flexible shafts for small ducts with bends. The EPA recommends soft brushes for fibreglass duct board and for sheet metal, so you do not damage the wall.

1. Construction dust in new sheet metal: standard brush, under negative pressure.
2. Old, stuck on dust in a hall: more aggressive Tynex brush.
3. Duct board or fragile material: soft brush, no biocides (the EPA has approved none for fibreglass duct board).
4. Small ducts with bends: flexible shaft.

How to match the brush to diameter and material is explained under duct brush for cleaning contractors. The machines they fit on can be found in the overview to air duct cleaning tools explained.

Duct cleaning Lelystad in industrial halls

In halls used for production or storage, it is often about dust removed by local exhaust ventilation. Article 4.5 of the Working Conditions Decree (Arbobesluit) requires that when contaminated air is removed, enough clean air is supplied at the same time. If an extraction duct becomes contaminated, the extraction drops and that balance no longer holds.

Fictional example. A company notices that the extraction above a workbench pulls less than it used to. The filters have just been replaced. A camera inspection shows a layer of dust in the first section of duct after the capture hood. With a brushing machine under negative pressure, that section is clean in one pass, and the draw comes back. See also industrial extraction duct cleaning for a more extensive approach.

The lesson from the example: when the extraction weakens, check the filter and the first metres of duct together. In many cases the problem sits close to the source, where the concentration of dust is highest.

For advice on the right machine or brush set, you can request a quote from Lamers, ask for a callback or ask for duct cleaning advice for businesses. It helps to have the duct diameters, the material and the type of building at hand.
