Air duct cleaning in Helmond

Helmond in figures: one in five businesses makes or processes something

Helmond has 95,874 inhabitants and ranks 33rd among Dutch municipalities (CBS 2024). The breakdown of establishments shows where the maintenance work lies:

Percentages calculated on the total per municipality. Where the neighbouring city is mainly offices, Helmond leans more towards manufacturing. That means more local exhaust ventilation, more production dust and more often a combination of factory hall, canteen and office under one roof.

Process extraction and EN 15780: which yardstick applies instead?

EN 15780 provides cleanliness classes, an assessment of the need for cleaning and frequencies for ventilation systems in buildings. The standard is explicitly not intended for industrial process installations. For the extraction at a welding or grinding station you therefore need to look elsewhere for guidance:

• Workplace limit values: Volandis gives 10 mg/m³ for inert inhalable dust and 5 mg/m³ for respirable dust, as an 8 hour time weighted average.
• Local exhaust ventilation: according to Volandis, a flexible extraction system close to the work is the basis.
• Testing local exhaust ventilation: the British Health and Safety Executive (HSE) requires local exhaust ventilation to be thoroughly examined and tested at least every 14 months, with the report kept for 5 years. That is British regulation, but a useful benchmark for your own maintenance plan.

For the office and canteen sections of the same building, EN 15780 remains the framework. How the standards fit together is explained under VDI 6022 ventilation hygiene for cleaning contractors.

What the Arbobesluit requires of extract and supply

Article 4.5 of the Arbobesluit deals with hazardous substances. It states that when contaminated air is extracted, sufficient clean air must be supplied at the same time. Well functioning extraction is therefore only half of the story: the supply air to the hall must also be in order.

In addition, Article 6.2 requires sufficient uncontaminated air at the workplace, an installation that is always ready for use and a monitoring system that signals faults where health requires it. Dirty ducts and filters work against this, because they reduce the airflow.

Combustible dust adds another layer. Fine wood dust creates an explosion hazard; the Dutch trade journal Brandveilig names extraction installations, spark detection and ATEX as points of attention. If you work in such an environment, always agree the cleaning method with the person responsible for explosion safety.

Duct cleaning Helmond: a maintenance plan for the facilities team

A manufacturer with its own maintenance department can plan most of the duct work itself. This sequence keeps it manageable:

1. Make a list of all extraction points and the ducts behind them, kept separate from the building ventilation.
2. Record for each extraction point which dust is released: metal, wood, fumes or oil mist.
3. Schedule a fixed test of the local exhaust ventilation, for example within the 14 month interval the HSE mentions.
4. Inspect the ducts with a camera where dust settles: horizontal sections, bends and just before the fan.
5. Clean under negative pressure, so the dust does not end up back in the hall.
6. Keep measurements and photos, so you can spot trends and show what was done during an inspection.

More about the approach in production environments can be found under industrial air duct cleaning.

Which equipment suits workshop ducts?

Workshop ducts are often robust, round or rectangular, and contain coarser or stickier dirt than office ducts. That asks more of the brush.

For wider ducts, ask Lamers what is possible. The DC4 duct cleaning machine in practice is the basis for most workshop ducts. All machines side by side are shown under duct cleaning kit in practice, and the means of creating negative pressure under vent caps for duct cleaning for businesses.

Fictional example: a metalworking firm with a canteen and an office

A metalworking company has a hall with four welding stations, a canteen with a small kitchen and an office above the workshop. That is three systems with three regimes:

• Welding extraction: a fixed test of the local exhaust ventilation, inspection of the ducts for deposits of welding fumes, cleaning with a more aggressive brush under negative pressure.
• Canteen kitchen: cleaning the grease filters regularly, inspecting the extract duct for grease.
• Office: inspection at the intervals from EN 15780, cleaning when there is excessive dust.

The mistake that is often made: putting everything on one interval. The welding extraction then gets too little attention and the office too much.

A simple way to avoid this is to give each system its own line in the maintenance plan, with its own trigger: a test date for the welding extraction, a grease check for the canteen and an inspection interval for the office.

Ventilation duct cleaning Helmond and in neighbouring Brabant municipalities

Anyone working from Helmond also ends up in the neighbouring municipalities. For air duct cleaning in Eindhoven the picture is more office oriented, with 28.2% business services. In Meierijstad, just as in Helmond, 20.6% of establishments are in manufacturing and energy (CBS 2024), so a kit for workshops is also well suited to ductwork cleaning for Meierijstad businesses.

All municipalities are listed under ductwork cleaning per municipality for businesses. Ask Lamers for advice on a kit that matches your mix of hall, kitchen and office.
