FIELD: electrolytic metallurgy. SUBSTANCE: method provides for partial or full screening of tanks table surfaces both in loaded with tools and members state or not loaded state of tanks correspondingly and adjustment of gasses, sprays and vapor removed amount from table surface of tanks in their wall sucking pumps. Processes of adjustment of gasses, sprays and vapor amount removed from table surface of tank in its wall sucking pumps and of full screening (descreening) of tank table surface are exercised in synchronism and interdependently. In the case, processes of full screening (descreening) of tank table surface are exercised in horizontal plane in respect to tank table surface, and processes of partial screening (descreening) - in vertical plane in respect to tank table surface. Method provides realization of full and partial screening (descreening). EFFECT: increased reliability and efficiency of screening and removing of harmful gasses, sprays and vapor from electrochemical plating processes and hot cleansing tanks. 3 cl, 2 dwg
