LTG Fine Filters

Product catalog summary
Overview: The document provides technical specifications and operational details for LTG Fine Filters, specifically the CompactDrum Filter (CDF) and UpflowDrum Filter (UDF) models, designed by LTG Aktiengesellschaft. These filters are engineered for optimal filtration capacity, operational safety, energy efficiency, and space utilization.
Specifications: The CDF and UDF filters are available in various configurations, including horizontal (CDF) and vertical (UDF) flow designs. They are suitable for a wide range of temperatures and solid concentrations, making them versatile for both machine exhaust and room air applications. The filters are equipped with regenerative cleaning systems, either continuous or intermittent, depending on the setup.
Design and Operation: The filters consist of multiple drums (2, 4, or 8) and can be configured for blow-through or pull-through systems. Cleaning is achieved through rotating suction nozzles driven by gear motors. The CDF model offers modular arrangements, allowing multiple units to be installed side by side or stacked, depending on air volume requirements.
Advantages: Key benefits include high performance density, no pressure fluctuations, long filter media life, easy media replacement, and low maintenance costs due to the placement of drive elements on the clean air side. The filters are also available in special designs for high temperatures, anti-static applications, and explosion protection.
Technical Data: The document provides detailed technical specifications, including filter area, drive power, dimensions, and achievable filter classes. For instance, the CDF-2 model has a filter area of 5 m² and dimensions of 2650 x 800 x 1672 mm.
Accessories and System Solutions: The document describes additional components such as prefilters (TVM/TVN and VFD types) and complete compact filter units (CFU-CDF and CFU-UDF). These systems offer enhanced filtration by separating and compacting coarse and fine particles.
Applications: The filters are part of a broader range of air technology solutions offered by LTG, including air conditioning systems, air diffusers, and process air technology. The company also provides engineering services in fluid dynamics, thermodynamics, acoustics, and customer-specific solutions.

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 several units). By choosing from a variety of filter media, both highest filtration outputs and filter surface loads are...

LTG UpflowDrum FILTERR type UDF, Accessories Prefilter (Flow Classifier) type VFD Version with prefilter, Dimensions 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...
