Top filter for dedusting of exhaust air of silos and containers, e. g. during pneumatic filling.

The INFA-JETRON AJB is a fully automatic silo filter for dust separating of exhaust air from silos or containers filled by pneumatic pressure. The easy handling during assembly and maintenance, the durability and reliability as well as the low price have satisfied our clients since launch of this filter. A special design for low temperatures down to -40 °C is available as well as a version for food, where all components in contact with the product are approved according to regulation EU 1935/2004 and EU 10/2011.

The version as top filter (INFA-JETRON AJP ..2) is venting filter, to carry out loading processes without dust emissions. It is built very sturdily to install it directly above the loading system at the silo. The filter cartridges are arranged in parallel. This reduces depth of the filter housing and makes their access easier in case of maintenance. With 15 m² and 20 m² filter surface the INFA-JETRON AJP ..2 is generously equipped for this job. The filter cartridges are changed in normal operating height via a big access door to the raw gas side. A fan flanged at the clean gas chamber takes care for the necessary suction pressure in the loading system.

The INFA-JETRON AJP ..4 silo filter uses the advantages of the AJB and matches them with identical flange size of the shaker filter AM 204, which has been installed on silos for many years. The connecting flanges on the silos don‘t have to be changed if a mechanically cleaned AM 204 is exchanged by a jet-pulse filter. These costs are saved if investing in a new filter. The filter can be applied for de-dusting of pneumatic or mechanical conveying processes as well as of processing machines, e.g. dosing plants, sieves, mills, mixers, air locks, sack tipping units etc.

Top filter of series INFA-MAT type AM204 are sturdy filter units. They are cleaned mechanically. Cleaning of filter media with the shaking system ensures an effective removal of dust deposits on the filter pocket. Depending on the application, design of the filter is with or without fan. During cleaning, the fan is turned off automatically. Easy access to the filter media is possible because of a maintenance-friendly door. The filter pockets are fastened in a removable filter frame that can be entirely moved in case of filter change.
