Using a central dust exhaust system with a widespread pipe system and many sockets, the dust spilled on the floor can be sucked in from every spot. A flexible suction hose is plugged in the socket of the suction pipe if required. The dust is aspirated by suction pressure that is generated by a vacuum pump and then guided to the filter unit. A big part of the dust lands in the filter‘s hopper. The fine dust fraction is separated on the filter media and dropped into the hopper by an efficient and full automatically cleaning with pressurized air. The dust disposal is usually made by rotary valves, whereas the dust can be collected centrally and returned to the production process.

Project for potash
Potash was generated several hundred million years ago, but not discovered until 1856. It proved very fast to be a powerful fertiliser. The second largest volume worldwide is located in the Russian region Perm. There, the Russian group EuroChem exploits with a greenfield project an extensive deposit and production site. The expoitation and processing facility will be commissioned end of 2017.

Part of the capital expenditure are nine pocket filters of the series Infa-Jet AJN. The filter units, reinforced for suction pressure down to 0.5 bar, are designed for a dust load < 20 g/m³ and a volume flow of 3,000 m³/h each. Delivery is carried out by Infastaub RUS.

Project for a steel works
Kazakhstan has a fabulous wealth of natural resources and is also worldwide well up mining. A concentration of resources is in the region Aktobe. The most important company for mining of chrome ore including processing is the company Kaschrom, a subsidiary of the Kazakh Company ERG for natural resources. The first ton of ferrous alloy was produced there in 1943.

Three pocket filters of series Infa-Jet AJN are the heart of a new central exhaust system. The order was also delivered by Infastaub RUS. The filter units are designated for exterior installation with temperature ranges from -40 to +40 °C. The cleaning unit of the filter is therefore built in a heated and thermally insulated protective housing. This way a flawless operating is also guaranteed during winter time.
