A slide-rail extraction is used when the welding work require precise but linear flexible extraction. The slide-rail extraction consists of an aluminum channel with inlaid rubber lips, a sliding carriage with mounted fitting, exhaust arm and extraction hood. The channel is connected to a fan.

The sliding carriage is guided vertically or horizontally across the aluminum extraction channel. The connector is mounted between the rubber lips of the channel. By the resulting vacuum during suction the fitted in the suction rubber lips pull together. The channel is closed thereby. The connector pushes apart the rubber lips and creates a gap, thereby the polluted air is sucked through the exhaust arm into the rail channel.

The polluted air is passed through the channel and via a pipe system into a filter. The combination of linear movable carriage and a flexible exhaust arm guarantees an efficient, precise extraction along a straight line.
