Characteristics: • Bags made with a porous matter to allow the water and drying air passage, and prevent in the same time from the clogging of the retained solids. • Made of AISI 304 stainless steel. • Filter bags made via drying and fixing process. • Motorized valve with security lock and subsidiary valve. • Level probe connected to an instrumentation board. • The filtration process is automatic and its filling is made by gravity. • Low maintenance and power costs. • High efficiency, allows to obtain dry matter between 10 and 20% after a few hours, and dry matter between 40 and 80% after outdoor storage.
