Innovation is one of TNO’s core tasks. In recent years we have developed many pioneering new tool concepts, a lot of which have resulted in prototypes of products with minimising dust emissions as one of their core features.

We work with commercial partners to produce effective solutions for the marketplace. This combination of our technical knowledge and their business know-how has proven a successful approach. We possess a wide variety of design tools and excelling testing facilities, which we are happy to share with you.


Our current innovation projects include...


  • Development of wet scrubbers for saw benches.
  • Development of multicyclonic filtration systems for vacuum dust extractors.
  • Development of multicyclonic filtration systems for industrial dust extraction units.
  • Development of on-tool extraction for welding torches.


For the above projects, TNO is looking for partners to help develop new dust-free products. If you are interested or would like more information, please e-mail or call +31 88 866 3324.

Successful TNO innovations

On these pages you will find examples of successful TNO innovations which are now widely used in the construction industry.


The angle grinder is the biggest polluter on any building site. It can emit huge amounts of carcinogenic respirable crystalline silica (RCS) into the employee inhalation zone and the rest of the workplace. These concentrations often exceed the statutory occupational exposure limit by a factor of up 100. In response, TNO has developed a dust hood so effective that it can reduce that to an acceptable level, within the legal limit. Several versions have been produced: one for 230 mm grinders, one for 125 mm grinders and one specifically for stonemasonry use.

A second innovation is an on-tool extraction system for chipping hammers and breakers, as shown below. That allows for two hours of continuous use per eight-hour working day.
