The compact filter unit consists of a fan module, a prefilter module and a fine filter module, the LTG UpflowDrum Filter® type UDF. It is particularly suitable for fibrous dust. Contrary to traditional drum filters, the dust-polluted air passes the UDF vertically through the filter drums.
This allows keeping the floor space re-quired for the unit very small. The dusty air passes through the filter drums from the inside, dust particles are collected on the inside where they are continuously removed. The discharged air is clean, i.e. the filter may be operated directly on the production floor. The outside of the filter and any drive and control components are located on the clean air side and, thus, are protected against any dirt. Continuous cleaning allows to recycle of nearly 100 % of the collected material.
Continuous regeneration also provides a steady pressure drop within the system. Dust concen-trations inside the filter are minimized with a positive effect on the zone division in explosion hazard areas contrary to traditional systems. The air flow is generated by an integrated radial fan. The pre-separation of coarse particles is done mechanical through a separator with continuous cleaning. The coarse particles themselves are continuously removed. This kind of coarse filtration without rotating parts and without filter media is wearless and low-maintenance. One fine filter module comprises of filter drums continuously cleaned by rotating nozzles.
