Double protected dust filter systems to assure the lowest emission of dust, suits to the most sharp enviromental protecting directions.

To reduce enviromental dust incidence, wich caused by the feeding of cement silos at mixing plants, there are many types of filter-sytems in use. Vibration-cleaning dust filters can be added to the top of the silos individually, or central dust-filtering system can be added apart from vibration filters, with a high-output suction-fan unit.
Filter cartridges are made from special polyester. Besides vibration cleaning, cartrigdes can be cleaned with air or warm water cleaning, yearly.
Central filter system can be placed on the top of a silo, instead of traditional dust filters. Filter can be placed above the mixer too. All the silos are connected to the central filtering unit. Suction pan unit assures relative vacuum, during the feeding of the silos. Vacuum protects the filter unit, and the silos from damage cause during the feeding procedure.
Feeding tubes of the silos are transformed at the plantation. A switch assures the controlling to detect the feeding tube of the truck, wich starts the cycle of the filter. System automaticly controlls the running of the vibrators, and the working of the sucktion-fan unit, during feeding procedure.
Duct of the fan connets to a security filtering-signal bag, wich stops dust emission, in the case of the mechanical damage of the filter cartridge.
