1 Technical Documentation LTG Fine Filters Type CDF / UDF

2 LTG Fine Filters Type CDF and Typ UDF Only precise adaptation of the filter parameters to the air volume to be filtered will ensure the optimum of - filtration capacity - operational safety - use of energy - utilization of construction space. The LTG fine filters type CDF and type UDF perfectly meet these requirements. Completely assembled units are used for a filter system. The cleaning is performed continuously (single unit) or, saving energy, intermittently (combination of severalunits). By choosing from a variety of filter media,both highestfiltration outputs and filter surface loads are achieved. Suitable for use in a wide range of temperatures and solids concentrations, the LTG fine filters type CDF and type UDF can be used for machine exhaust air as well as room air. Mode of Operation The inside loaded filters consist of 2, 4 or 8 individual drums. They can be used for blow through or pull through systems. Drum cleaning is realized by rotating suction nozzles performing an overriding longitudinal movement. Advantages Regenerative filter unit due to continuous cleaning (with several filters intermittent cleaning is used in controlled intervals). High performance density, high surface loading No pressure fluctuations High filter capacity and performance due to selected filter media Long filter media life time Easy filter media replacement Low maintenance costs since all drive elements are located on the clean air side Compact sturdy design due to frame construction High operational safety The movements are generated by separate gear motors using round drive belts. All drive elements are located on the clean air side.

9 LTG UpflowDrum FILTER R type UDF, Accessories Prefilter (Flow Classifier) type VFD The prefilter type VFD operates purely hydraulically. During classifying, the solid particles are separated by gravity and inertia forces from the airflow. The particles impact at flow velocity on the baffle plate of the classifier and are extracted isokinetically or with a low excess speed. Extraction itself is performed energy-efficiently using an eddy sink. This continues to ensure an optimum and uniform distribution over the extraction width. The pressure loss from the classifying stage itself corresponds to the pressure loss of a comparable filter fabric.
