  • the water and air are brought into intimate contact with each other owing, partly to the fact that the air is caused to pass repeatedly through spray, and partly that it is caused to come into contact with surfaces damped by spray.
  • the output of the apparatus is thus in creased without a great deal of excess water.
  • the air is pushed through the exhaust drum 18 into the room. At this point it is caused to pass through the slot 19 where large water drops, which may have been carried out, are separated by the said drop catcher 21.

  • the shoulder may of course be formed by applying a special plate or by bending in a part of the wall of the nozzle or the like.
  • the apparatus may freeze up. Should this occur in the upper portion of the apparatus, the rotatable parts may be damaged. This risk is avoided by a device, by means of which the water supply is automatically shut oil when freezing takes place. This is accomplished by passing the pipe conduit 11 through the lower portion of the apparatus, where it is surrounded by the air sucked in. The freezing will take place in the lower portion of the pipe, whereby the water supply to the upper part is automatically stopped.
