1 DF dsorption Filter MIN FETURES & BENEFITS: ctivated carbon filter with integrated particle filter for the retention of oil vapours, hydrocarbons and odours as well as particles from compressed air or gases in industrial applications Innovative filtration technology; high adsorption capacity and retention rate with low differential pressure Validated performance data acc. to ISO 12500; reliable achievement of compressed air quality acc. to ISO Flow-optimised design, minimum pressure loss for economic compressed air purification (saving of energy costs) dsorption filter INDUSTRIES Chemical and pharmaceutical industry PCB assembly and CD manufacturing Surface finishing Machine building industry and plant engineering / construction Energy and power generation Donaldson Filtration Deutschland GmbH Büssingstr. 1 D Haan Tel.: +49 (0) Fax: +49 (0) CP-de@donaldson.com Web: Technical alterations reserved (6/2018) F119068_06_2018_ENG

2 PRODUCT DESCRIPTION The adsorption fi lter Ultrac consists of 2 fi lter stages. t the adsorption stage oil vapour, hydrocarbons and odours are removed by activated carbon adsorption. Particles are removed at the depth fi lter stage, consisting of microfi bre fl eece. In addition, support fl eece and an outer stainless steel support sleeve ensure proper fi xation of the adsorption and fi lter stage. The fl ow direction through the fi lter is from inside to outside. t appropriate prepurifi cation (see Recommended prepurifi cation ) a residual oil content of < 0,003 mg/m³ is achieved. The specifi ed performance data for the achievement of the compressed air quality classes according to ISO were validated according to ISO Cross section of the depth filter The filter element is designed and developed for the following applications: Downstream applications: Final fi ltration for control and process air, processing of technical oil-free compressed air Breathing air applications: Removal of oil vapours, miscellaneous hydrocarbons as well as particles in breathing air applications utomotive industry: Purifi cation of paint and lacqering fi nishing air 2 / 5
