Suction system for vapours and gases

摘要

Suction for removal of unwanted vapours and gases takes place through a suction cap (5) or suction pipe with a suction nozzle (4). The pipe and nozzle are movable in a slotted suction channel (1) with lip sealing (3) and a runner (2). The complete slotted suction channel system is constructed as a coordinate axis system so that suction can be carried out in any position in it. Both longitudinal axes (X1, X2) in any length form a suction channel (10) in which moves a transverse slotted suction channel (Y axis) which forms a gate (12).
