Air duct cleaning in Amsterdam

What do 206,195 establishments say about duct maintenance?

A large number of establishments does not tell you directly how many metres of duct there are. It does say something about the type of work: many small units, many different owners and many shared buildings. With a population density of 4,950 inhabitants per km² and urbanisation class 1 (extremely urban), you often work in cramped plant rooms and above lowered ceilings.

What stands out is the spread: no single sector dominates, except business services. Anyone cleaning ducts in Amsterdam therefore needs a kit that can handle a 400 mm office duct as well as a 100 mm bathroom extract.

Duct cleaning Amsterdam offices: where does the dust collect?

In an office, dust builds up mainly in extract ducts, behind grilles and in horizontal sections just after a bend. The Working Conditions Decree (Arbobesluit, article 6.2) requires sufficient uncontaminated air at the workplace and a ventilation installation that is always in good working order. A clogged duct does not achieve that.

For the question of how clean is clean enough, EN 15780 is the guideline. The 2025 version replaces the one from 2011. According to trade publications, medium risk buildings such as offices, hotels and schools have a dust limit below 3.0 g/m², with 4.5 g/m² for secondary ducts. Those values come from a trade article, not from the text of the standard itself, so check them with your client.

In practice: start with a visual inspection at a few representative points, record what you see and only then decide on the method. More about these buildings is covered under office ventilation duct cleaning.

Hotels and public spaces: small diameters with many bends

With 31,130 establishments in culture, recreation and other services (15.1%), Amsterdam has relatively many buildings with rooms, changing areas and washrooms. Those are ducts with small cross sections and short distances between the valves. A heavy machine is often overkill there.

• For short, narrow sections, Danduct PD4 for cleaning contractors works well: the PD4 runs on a cordless or mains power drill, with a shaft of 2.5 to 7.5 metres.
• Where a brush will not fit, for example from 30 mm or through tight 90 degree bends, choose air nozzle duct cleaning for cleaning contractors. The built in camera with LED shows what you are cleaning.
• Work per room or per shaft, so the rest of the building stays in use.

How to organise that in a hotel is worked out on the page about ventilation of hotel rooms.

Which machine suits which type of building in the capital?

No machine does everything. This selection table helps you make a first choice. Lamers advises on the final choice.

The Airnozzle needs a compressor delivering 700 litres per minute or more at about 10 bar. In a city centre building without its own compressed air network you will have to bring one along. A full overview of machines, shafts and brushes is available under duct cleaning equipment for businesses.

Fictional example: office floors above a restaurant kitchen

Take a fictional building: four office floors with a shared extract system and, on the ground floor, a restaurant with its own kitchen extraction. Those are two different jobs.

1. Office ducts: dry method with a rotating brush and negative pressure. According to Eurovent, dry methods are usually sufficient for supply and general extract.
2. Kitchen duct: grease calls for a wet method. There is no statutory cleaning frequency for hospitality, but KHN (Royal Dutch Hospitality Association) mentions at least once a year as common practice, and fire insurers require regular maintenance.
3. Evidence: for the kitchen duct, the insurer wants a report with photos. For the offices, a short inspection report per floor is useful.

How to work dust free in a busy city centre

In an occupied building, the biggest complaint is not the dirty duct but the dust that escapes during the work. Two measures prevent that.

First, you keep every section being cleaned under constant negative pressure with an extraction unit. If that unit exhausts inside the building, a HEPA filter with 99.97% at 0.3 µm is mandatory. Second, you close off the work zone: duct balloons seal a section of duct and foam caps cover valves and diffusers. Everything about this is explained under negative pressure HEPA extraction for cleaning contractors.

In offices, preferably plan the work outside working hours, and in public spaces put up a short notice. That prevents questions from users who hear a machine running above their desk.

How often should ventilation duct cleaning Amsterdam buildings take place?

There is no fixed statutory term for offices or hotels. Guidelines do give something to hold on to:

• According to a trade article on EN 15780, you carry out a risk assessment every 2 years, and every year in high risk buildings such as hospitals and labs.
• Under VDI 6022, a hygiene inspection follows every 2 years for installations with humidification and every 3 years without.
• For kitchen extraction, Rabobank advises professional cleaning at least once a year, twice with intensive use.

You clean on the basis of the inspection, not the calendar. The full story on intervals is explained under duct cleaning frequency for cleaning contractors.
