For installers, facilities teams and cleaning contractors that means: many smaller locations, spread across the villages, and few office towers. The equipment must therefore be mobile and quick to set up. On this page you will read how to organise that, which Danduct Clean packages fit and what to look out for in agricultural, production and hospitality premises. Lamers Reinigingstechniek in Zelhem supplies the equipment.

A rural merged municipality: what the figures mean
Land van Cuijk has 91,722 inhabitants and ranks 39th of the 342 municipalities. The density is 269 inhabitants per km² and CBS gives the municipality urbanisation class 4, hardly urban. For comparison: its land area is 6.5 times that of neighbouring Nijmegen.
| Sector | Establishments | Share | Duct maintenance |
|---|---|---|---|
| Business services | 2,540 | 21.0% | Smaller offices and business units |
| Trade and hospitality | 2,245 | 18.6% | Shops, places to eat, kitchen extraction |
| Government, education and care | 1,950 | 16.2% | Schools and care locations in each village |
| Manufacturing and energy | 1,815 | 15.0% | Workshops and production |
| Agriculture, forestry and fishing | 1,085 | 9.0% | Farm buildings on the yard |
| Culture, recreation and other services | 1,175 | 9.7% | Sport, recreation and club buildings |
The share of agriculture is 0.3% in Nijmegen and 9.0% here. Trade and hospitality, at 18.6%, also weighs more heavily than in many cities. Schools, shops and hospitality businesses are spread across the villages, each with its own ventilation system.
Working on the move between villages: which DC4 package?
If you visit three or four locations in one day, you want a machine that goes in and out of the van quickly. Danduct supplies the DC4 in packages:
| Package | Contents according to the manufacturer | Suits |
|---|---|---|
| Medium | Machine, shafts of 10 and 20 m, brush set of 7 pieces for 100 to 600 mm | Offices, schools and shops with short to medium runs |
| Large | Shafts of 10, 20 and 30 m, trolley, brush set plus aggressive brush set of 7 pieces, shaft holder | Varied work, including longer ducts and stubborn dirt |
With a trolley and shaft holder, moving between locations becomes a lot lighter. Both packages run on standard 230 volts, so you do not need a separate power connection. DC4 duct cleaning machine in practice cleans round and square ducts, vertically and through 90 degree bends. Which package suits your customer base is something you discuss with Lamers when you request a quote.
Agricultural businesses: do not forget the office and canteen ducts
With 1,085 establishments in agriculture, forestry and fishing, Land van Cuijk has many businesses in the countryside. The ventilation of livestock buildings and greenhouses is outside the scope of this page; separate rules apply to those. But many farmyards also have an office, a canteen or a processing room with ordinary mechanical ventilation.
Those very ducts are often forgotten. What you do know about them:
- The Working Conditions Decree (Arbobesluit, art. 6.2) requires sufficient uncontaminated air at the workplace and an installation that is always in working order. That also applies to an office on the farmyard.
- According to Milieu Centraal (Dutch public information centre), contaminated filters can blow moulds and bacteria along.
- In a laboratory study, an MVHR unit with heavily contaminated filters delivered 37% less supply air. Power consumption dropped slightly, so the problem was mainly too little ventilation.
If you process food on the farm itself, hygiene requirements for air flows and accessible filters come on top of this.
Ductwork cleaning Land van Cuijk in workshops and production
Manufacturing and energy accounts for 1,815 establishments. In workshops and small production companies, a local exhaust system often runs alongside the office ventilation. Volandis advises a flexible extraction system close to the work. That only works if the extract ducts do not silt up.
- Determine per duct whether it is general ventilation or process extraction. EN 15780 does not apply to industrial process installations.
- Look at which dust is inside. Fine wood dust and flour dust are combustible and require extra precautions.
- Choose the brush on material and contamination: soft, standard or the more aggressive Tynex brush.
- Work under negative pressure with extraction, so that the dust does not end up in the workshop.
More about heavy contamination in production is covered under industrial air duct cleaning. How to select the brush is explained under duct brush for cleaning contractors.
How often do you schedule maintenance for scattered locations?
With clients spread across the villages, a fixed schedule pays off. Use the known guide values as a basis:
| System | Guide value | Source |
|---|---|---|
| Extract ducts of mechanical ventilation | clean at least once every 8 years | Milieu Centraal |
| Filters of balanced ventilation | replace twice a year | Milieu Centraal, Brink |
| Hospitality extract duct | at least once a year, twice with frying | Rabobank |
| Air handling with humidification | hygiene inspection every 2 years | VDI 6022 |
| Local exhaust ventilation in a workshop | thorough test every 14 months | HSE (United Kingdom) |
Combine filter changes with a visual check of the ducts, and plan larger cleaning jobs per village in one round. More on intervals per building type can be found under ductwork cleaning schedule for cleaning contractors.
A simple route plan per village
- List every client per village with system type and last cleaning date.
- Combine filter visits and duct checks on the same day.
- Keep a fixed kit in the van, so that no second trip is needed.
- Record findings per building, so that the next round can start from the notes.

Frequently asked questions: air duct cleaning Land van Cuijk
Which DC4 package suits an installer who works all over Land van Cuijk?
For varied work at many locations the Large package is often practical: shafts of 10, 20 and 30 metres, a trolley, a shaft holder and an aggressive brush set next to the standard one. If you mainly work in smaller offices and schools, the Medium package with shafts of 10 and 20 metres may be enough.
How many agricultural businesses does Land van Cuijk have?
In 2024 CBS counted 1,085 establishments in agriculture, forestry and fishing, 9.0% of the 12,070 establishments. In neighbouring Nijmegen that share is 0.3%. Many of these businesses have an office or canteen with ordinary ventilation next to their livestock buildings or greenhouses.
Do duct standards also apply to an office on a farmyard in Land van Cuijk?
For the workplace, yes. Article 6.2 of the Working Conditions Decree requires sufficient uncontaminated air and an installation that is always in working order, also in an office or canteen on the farmyard. For the cleanliness of the ducts, EN 15780 is the usual standard for ordinary ventilation systems.
Do I need a special power connection for the DC4 in Land van Cuijk?
No. The DC4 runs on standard 230 volts, so an ordinary socket is enough. That makes the machine suitable for smaller premises in the villages, where there is no three phase power near the duct. Do pay attention to a safe cable route when you work in a workshop or canteen.
What happens when the filters of an MVHR unit in Land van Cuijk become contaminated?
In a laboratory study, an MVHR unit with heavily contaminated filters delivered 37% less supply air. Power consumption dropped slightly from 71 to 66 watts, because less air was moved. The main result is underventilation. Milieu Centraal and Brink advise replacing filters at least twice a year.
How large is Land van Cuijk compared with Nijmegen?
Land van Cuijk has about 341 km² of land, Nijmegen about 53 km². That is 6.5 times as large, while Nijmegen has more than twice as many inhabitants. For maintenance work this means more travel time between locations in Land van Cuijk, so a complete kit in the van saves time.
May I use EN 15780 for the extraction in a workshop in Land van Cuijk?
Not for the process extraction. EN 15780 does not apply to industrial process installations. For the general ventilation of the office and canteen in the same workshop it does. For local exhaust ventilation, look at occupational hygiene and dust limits, such as 10 mg/m³ inhalable and 5 mg/m³ respirable inert dust according to Volandis.
How often should a restaurant in one of the Land van Cuijk villages clean its extract duct?
There is no statutory frequency, but fire insurers require regular maintenance. Rabobank advises professional cleaning at least once a year and twice a year for a restaurant that fries. According to KHN, you clean more often with intensive use of a grill, fryer or wok.
Which brush do I choose for caked on dust in a Land van Cuijk workshop?
Danduct supplies soft, standard and more aggressive Tynex brushes for ducts from 100 to 600 mm. For stubborn dirt on sheet steel, Tynex is an option. For duct board or fragile material, use a soft brush instead. Test on a short section first before you do the whole duct.
Does Lamers have a branch in Land van Cuijk?
No. Lamers Reinigingstechniek is based in Zelhem and supplies Danduct Clean machines to businesses throughout the Netherlands. You can request a quote, ask for a callback or send a question. The cleaning itself is done by your own staff or by a specialised cleaning contractor.
