Abstract

The invention concerns an apparatus and. a method for the removal of gasses from electrolysis cells (21) by suction, the apparatus comprising a branch duct (3) for each electrolysis cell, a main duct (4) connecting the branch ducts to a gas treatment centre (5) and a central suction fan (6) providing for at least part of the suction, wherein one or more of the branch ducts are provided with supplementary suction means (8) and wherein control means (9) to control the supplementary suction means and pressure monitor means (11) are provided, wherein the control means are adapted to control the supplementary suction means in dependence from changes in the monitored pressure with respect to a reference pressure.
