It is a specific solution for aspiration of grain and feed mixtures transport routes by means of local - point filters. The filter units in horizontal design are used for dust removal of chain conveyors - redlers. Vertical filters are used for dust removal from elevators. All the filters used were of the G&G Local JET type placed directly on the aspirated conveyors.

The G&G Local JET filter unit is a filter unit equipped with automatic regeneration of the non-woven filter media by means of a counter-current of pressurized air. The filter media has a service life of more than 10,000 operating hours, without the need for any manual refinishing. The filter medium is a flat, smooth, non-woven sleeve with a weight of 550 g/m2. The filter medium does not contain any folds in which dust can settle and is very mechanically resistant to tearing or puncture. The residual drift of dust particles at the exhaust is in the range of 1 - 3 mg/m3. The exhaust fan may be equipped with a circular silencer at the outlet to reduce the noise load from the filtering device. The dust discharge is directed back into the material path.

A total of 13 G&G Local JET filtration units were used for aspiration. Of these, 7 horizontal filters were used to dedust the redlers and 6 vertical filters were used to dedust the elevators.
