The ultra-clean filter tank ensures that less than 5 mg/nm3 of material dust is released into the environment. The air which flows through the vent lines of the material handling system goes through this filter package. The filter tank can handle high air flow and volume of material loading of fine particles. The dedicated filter cartridges are easy to change and incorporate integrated pneumatic pulse cleaning. The filter tank collects the dust particles during conveyance operations. After the filter tank is completely full, it is pressurised and the material can be conveyed to another destination. This de-dusting unit is remarkably quick, easy and clean compared to traditional filter bags or de-dusting units.
