Welcome!
AKPF web-site will continue with emphasis on needs of officials in charge of air pollution abatement.
In view of social and legal developments the former informal task force or working group called AKPF had to be transformed into a legal person, which is now called VERT-Association or VERT-Verein; this association is registered as a non profit organisation in Switzerland (Trade Registry: Kanton Aargau, No.: CH-400.6.03438-9). For more information on VERT Association see www.vert-dpf.eu and www.vert-certification.eu.
The accomplishments of AKPF are numerous, as outlined in the about AKPF page (update is forthcoming).
| Watch a movie about particulate pollution and particulate filter technology: | Search the unique AKPF database of diesel particulate filter retrofit installations on construction vehicles and machinery in Switzerland. |
| Four SAE Fellows, experts of distinguished accomplishments, are now contributing to this web site. | |
| ETH Conference Papers on Health Topic, compiled by the VERT Association (also available on CD, contact us to order). | Soot Sling FTF—A movie showing soot release from an FTF. For more information, read Flow Through Filter (FTF) versus Diesel Particulate Filter (DPF). |
What’s New
18 August 2010: Emissions Control Concepts, a conference by IQPC, will be held in Wiesbaden, Germany on 29th November - 1st December 2010.
7 June 2010: Seven key messages regarding Diesel Particle Filters (DPF).
19 May 2010: AKPF and its successor VERT-Association have consistently urged to consider black carbon for global warming. Now, the control of black carbon emissions receives another voice of support—the Hartwell Paper authored by an international group of academics. The report calls for a new approach to restrain climate change, with less focus on CO2 and more attention to the control of other emissions, including black carbon.
6 May 2010: Updated version of the AKPF particulate filter database.
5 April 2010: LEZs in Europe, a press release by Sadler Consultants.
