Air duct cleaning in Doetinchem

Doetinchem as a working town in the Achterhoek: the figures

Doetinchem has 59,623 inhabitants and 26,822 households, and ranks 74th of the 342 municipalities (CBS 2024). Its urbanisation level is 3, moderately urban, with 754 inhabitants per km².

Industry, agriculture and trade and hospitality together account for almost 38% of the establishments. For comparison: in Arnhem the share of industry and energy is 9.4%. To see the larger cities in Gelderland, look at air duct cleaning in Arnhem and ductwork cleaning for Nijmegen businesses.

Ventilation duct or process extraction: why the difference matters

A common mistake is to treat every air pipe the same way. EN 15780 sets out cleanliness classes, assessment, method and frequency for ventilation systems, but is explicitly not intended for industrial process installations. The revised version from 2025 applies to ventilation systems except industrial, medical and laboratory facilities.

For process extraction you therefore look at other frameworks. The British HSE requires local exhaust ventilation to be thoroughly examined and tested at least every 14 months, and the record to be kept for 5 years. For metalworking, Volandis gives limits for inert dust of 10 mg/m³ inhalable and 5 mg/m³ respirable (8 hour TWA), and a flexible extraction system close to the work. For factories in general, go to industrial extraction duct cleaning.

Wood, flour and chips: dust that can ignite

In the woodworking industry, fine wood dust is a known explosion risk, with attention to extraction installations, spark detection and ATEX. For flour, meal and sugar, TNO states that an explosion is only possible above 60 g/m³ of fine dust in the air, but deposits in ducts can create exactly such a cloud when disturbed.

• Do not let deposits build up in extraction ducts; plan inspections at fixed moments.
• In EX zones an industrial, ATEX 114 certified vacuum cleaner is essential (TNO).
• Do not use compressed air to blow work areas clean; that puts dust into the air.
• Record who is responsible for the extraction and how often it is checked.

Bakeries and food companies in the region

For bakeries the Health Council of the Netherlands recommends a health based value of 0.2 mg/m³ of inhalable wheat flour dust over 8 hours; that is advice and not a statutory limit. In Belgium a limit of 0.5 mg/m³ applies. Alimento and TNO are clear about the method: no compressed air, hand brushes or brooms for cleaning, but an industrial vacuum cleaner, for which an M class filter is sufficient.

For food companies, the NVWA (Netherlands Food and Consumer Product Safety Authority) requires that air does not flow from contaminated to clean areas and that filters and parts needing regular cleaning are easily accessible. More about flour dust can be read under extraction in the bakery.

Duct cleaning Doetinchem: which equipment suits industry and SMEs?

For most ventilation ducts in Doetinchem businesses, the Electric DC4 brushing machine in practice is the starting point, supplemented with ventilation duct brush for cleaning contractors of the right stiffness. LIFA AIR is a different manufacturer and not a Lamers product; the comparison shows where the range of the DC4 ends. The complete range is under duct cleaning kit explained.

Fictional example: a manufacturer with a canteen and a workshop

A manufacturer has an office with a canteen at the front and a workshop with local exhaust at the back. The facilities team cleans the ventilation ducts of the office and canteen itself, under negative pressure and with the valves sealed. The process extraction in the workshop falls under its own inspection regime with fixed check moments and a logbook. The kitchen extraction of the canteen gets its own rhythm for grease filters. That way each system has its own framework instead of one general schedule. This example is fictional.

Putting the three regimes in one shared maintenance calendar, each with its own colour, makes the split visible to everyone in the company and stops the workshop extraction from quietly falling under the office routine.
