Industrial filtration

The filters Ultra-Filter DF are intended for the processing of compressed air or other gases in different areas of applications. A bayonet fixing between filter head and filter bowl allows for the element to be removed together with filter bowl. Little installation height for the filter element exchange is required. Besides energy cost savings by the filter design, the use of the Economizer offers further saving achievements through timely replacement of the used filter elements. The most cost effective replacement time for the filter element is calculated and LEDs signal the necessity for a “filter exchange”. With 9 sizes the Ultra-Filter covers the performance range from 35 to 1100 m³/h flow rate and hence conventional compressor capacities between 2 and 120 KW.

Three versions are available:

• Standard (with Econometer and float drain)
• Plus (with Economizer and float drain)
• Superplus (Economizer with level-controlled condensate drain UFM-D)

The innovative three-stage filter DF-T(hree) is used for the purification of compressed air and gases in smallest places. The unique filter element combines 3 purification stages in one filter housing– a coalescence filter, an activated carbon adsorber and a high performance particle filter. It achieves quality class 1 acc. to ISO 8573-1:2010. The DF-T is ideally suitable as terminal filter, where the highest quality of compressed air is necessary and only small place for installation is available.

The DFX filters are intended for the processing of compressed air and gases in different industrial applications. The special design of the filter housing and filter element as well as the materials used allow an operation under extreme conditions. Applications under high and low operating temperatures and conditions with mechanical stress such as vibrations or shocks can be covered by the filter series.
The filter elements are available in 7 sizes that cover a performance range of a flow rate up to 600Nm3/h (for compressed air) at an operating pressure of 25 bar. The housing connections range from 3/8″ to 2″.Validated performance data acc. to ISO 12500-1 for reliable achievement of compressed air quality suitable due to the application acc. to ISO 8573-1.More on:

A cyclone separator has to remove the abrasive contamination, like solid and liquid particles and aerosols from the flow of air pressure. The emphasis is set here on the removal of water, which due to a condensation in the aftercooler at this point increasingly show as droplets or splashing water. Because of its low differential pressure and simultaneously lowered requirement of energy the cyclone separator offers substantial cost savings. In addition the higher filtration efficiency takes a positive effect on the subsequent compressed air adsorption and refrigeration dryers as well as on the filters. The DF-C cyclone separators are available in seven sizes, which match the current compressor capacities and the connection sizes of the Donaldson compressed air filters as well as the refrigeration and adsorption dryer product range. In addition, they are integrated in the current compressed air filter housing generation as the “Standard” (equipped with time-controlled condensate drains) or “Superplus”-Version (equipped with Ultramat UFM-D level-controlled condensate drain).

The adsorption filter r Ultrac A consists of 2 flter stages. At the adsorption stage oil vapour, hydrocarbons and odours are removed by activated carbon adsorption. Particles are removed at the depth flter stage, consisting of microfbre fleece. in addition, support fleece and an outer stainless steel support sleeve ensure proper fixation of the adsorption and filter stage. The flow direction through the fillter is from inside to outside. At appropriate prepurification a residual oil content of < 0,003 mg/m³ is achieved.
