With an ever increasing environmental aware- 6 ness and the common global goal to reduce 2 emissions and pollutions, Vianen has a respon- 1 sibility of contributing through the filtration of cooking fumes arising from commercial kitchen applications. In order to effectively filter all the grease, gaseous and other particles, proper filtration of the extracted fumes from these commercial cooking appliances is required.
