3nine guarantees clean air for employees at Expander System Sweden AB

By equipping their machine tools with 3nine Industries oil mist separators, Expander Systems was able to take control of the air quality in their workshop.

As part of keeping the air free from oil mist, Expander System has since 2014 chosen to invest in 3nine Industries oil mist separators in the Swedish production facility. In addition to minimizing the Nord-Lock Group’s overall climate footprint, the Group continuously strives to ensure a healthy working environment for its employees.

To help customers gain control over the air quality in their shop, 3nine Industries has recently launched a concept called “Clean Air Initiative”. The concept includes three parts; strategic planning, advanced technology and superior service. A 3nine Industries service technician will take air quality measurements in selected areas of a customer production facility where contamination is suspected. The data is prepared in a report and presented to the customer. If air pollution sources would be identified, a strategic action plan is formed in order to secure a healthy working environment with the customer. 


Oljedimavskilare AnnaIn addition to our most recent purchase from 3nine, an oil mist eliminator Anna, we also chose the Clean air initiative service provided by 3nine and have had measurement issued in our premises. We did not immediately suspect that we had problems with the air quality but felt that we did not want to take any risks since it concerns the health of our staff. Therefore, it was a relief to know that the air quality in the workshop is good and that we now know for sure that Expander Systems offer a healthy work environment for our employees.
