ABSTRACT OF THE DISCLOSURE A small, inexpensive apparatus for receiving and purifying the smoke generated at a welding station comprises four serially arranged chambers and a gas flow conduit, with a vacuum means for drawing the smoke through the conduit. The conduit is equipped with fixed vanes to induce circulatory motion of the gas therein, and a circumferential aperture so that heavy particles forced to the outside of the conduit by the centrifugal force induced by the vanes exit through the circumferential aperture. The gas and particles thus removed pass into a water bath, in which the particles are absorbed, the purified gas passing through the water and recombining with gas in the conduit, through an inlet aperture disposed in the second chamber. The purified gas proceeds out of the conduit in a third chamber, where it impinges upon a surface bearing adhesive coating to remove the fine suspended particles from the gas, and leave substantially clean air to issue from the apparatus.
